CNC processing route follows the following principles

CNC Lathe Feed processing route refers to the path through which the turning tool starts to move from the tool setting point (or the fixed origin of the machine tool), computer gong processing, Dongguan computer gong processing, high-speed CNC machining, mechanical parts processing, CNC processing, and then returns to the point and ends the processing program, including the path of cutting processing and the path of non cutting empty stroke such as tool cutting in and cutting out.

The feed path of finish machining is basically carried out along the contour sequence of the parts. Therefore, the key to determine the feed path is to determine the feed path of rough machining and idle stroke.

In CNC lathe processing, the determination of processing route generally follows the following principles.

① The accuracy and surface roughness of the workpiece to be processed shall be guaranteed.

② It can shorten the processing route, reduce the idle travel time and improve the processing efficiency.

③ Simplify the workload of numerical calculation and simplify the processing program.

④ For some reusable programs, subroutines should be used.

Advantages and disadvantages CNC machining has the following advantages:

① A large number of tooling is reduced, and complex tooling is not needed to process parts with complex shapes. If you want to change the shape and size of parts, you only need to modify the part processing program, which is suitable for the development and modification of new products.

② The machining quality is stable, the machining precision is high, and the repetition precision is high, which can meet the processing requirements of aircraft.

③ In the case of multi variety and small batch production, the production efficiency is higher, the time of production preparation, machine tool adjustment and process inspection can be reduced, and the cutting time is reduced due to the use of the best cutting amount.

④ It can machine complex surface which is difficult to process by conventional method, and even can process some parts which cannot be observed. The disadvantage of machining is the high cost of machine tools.

How to guarantee the stability of machining quality in CNC machining

Firstly, the number of tooling is greatly reduced, and complex tooling is not needed to process parts with complex shape. If you want to change the shape and size of parts, you only need to modify the part processing program, which is suitable for the development and modification of new products.

② The machining quality is stable, the machining precision is high, and the repetition precision is high, which can meet the processing requirements of aircraft.

④ It can machine complex surface which is difficult to process by conventional method, and even can process some parts which cannot be observed.

The disadvantage of NC machining is the high cost of machine tools, which requires maintenance personnel to have a high level. Computer gong processing Dongguan computer gong processing high speed CNC machining CNC machining CNC machining CNC machining or CNC machine tool is actually a kind of name in Hong Kong. Later, it was introduced into the Pearl River Delta of mainland China. It is a kind of mechanical processing technology called “CNC machining center” in Guangzhou, Jiangsu, Zhejiang and Shanghai. It is a new type of processing technology. The main work is to compile processing programs, that is to say, the original From manual work to computer programming. Of course, manual processing experience is required.

brief introduction

In fact, it is CNC milling machine tool. In Guangzhou, Jiangsu, Zhejiang and Shanghai, there is a person called “CNC machining center”, which is an automatic machine tool equipped with program control system. CNC machine tool is the abbreviation of computer numerical control. It is an automatic machine tool controlled by program. The control system can logically process the program with control code or other symbol instructions, and decode it by computer, so that the machine tool can move and process parts. The blank is processed into semi-finished products by cutting tool.

CNC machining (CNC machining) refers to the processing with CNC machining tools. CNC machining CNC index controlled machine tool is programmed and controlled by NC machining language, usually G code. NC machining G code language tells CNC machine tool which Cartesian position coordinates, and controls the tool feed speed and spindle speed, as well as tool converter, coolant and other functions. Compared with manual machining, CNC machining has great advantages, such as the parts produced by CNC machining are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be completed by manual processing. CNC machining technology has been widely promoted, most of the machining workshops have the ability of NC machining. The most common NC machining methods in typical machining workshops are CNC milling, CNC lathe and CNC EDM wire cutting (WEDM). The tool for NC milling is called CNC milling machine or CNC machining center. Computer gong processing, Dongguan computer gong processing, high-speed computer gong processing, mechanical parts processing, computer gong processing, CNC turning lathe is called CNC lathe center. NC machining G code can be manually programmed, but usually the machining workshop uses CAM software to automatically read CAD file and generate G code program to control NC machine tool.

Operation rules of CNC machining center

1. Before machining in each program, it is necessary to strictly confirm whether the tool is consistent with the program;

2. When installing the tool, it is necessary to confirm whether the length of the tool and the selected tool holder are suitable;

3. It is forbidden to open the door when the machine tool is running, so as to avoid flying knife or workpiece;

4. In case of tool collision during processing, the operator must stop the machine immediately, such as pressing the “emergency stop” button or “reset key” button or setting the “feed rate” to zero;

5. In the same workpiece, each tool setting should be kept in the same area to ensure the accuracy of cutting tool when connecting. CNC machining center operation rules;

6. If too much machining allowance is found in the process of processing, computer gong processing, Dongguan computer gong processing, high-speed computer gong processing, mechanical parts processing, computer gong processing shop must use “single section” or “pause” to clear x, y, Z values, and then manually mill them off, and then swing back to “zero” to let them run on their own;

7. During self operation, the operator shall not leave the machine tool or regularly check the operation status of the machine tool. If it is necessary to leave midway, relevant personnel must be designated for inspection;

8. The aluminum slag in the machine tool should be cleaned before the smooth knife oil injection to prevent the aluminum slag from absorbing oil;

9. Air blowing should be used in the roughening procedure and oil injection should be applied in the light knife program;

10. After the workpiece is off the machine, the burr must be removed in time;

11. When off duty, operators must make timely and accurate handover to ensure normal follow-up processing;

12. Before shutdown, ensure that the tool magazine is in the original position and the XYZ axis is in the middle position. Turn off the power supply and the general power supply on the machine tool operation panel in turn;

13. In case of thunderstorm, the power supply must be cut off immediately.

In addition to the above points, there are many things that we need to pay attention to from time to time. The system should pay attention to, and the machine should also pay attention to maintenance. In fact, most of the time, the machine will break down, to a large extent, and the user’s operation is improper. We do not pay attention to check the machine and do not warm up before starting up. Some companies have to process computer gongs in Dongguan due to the bad environment Processing | high speed computer gong processing | mechanical parts processing | computer gong processing shop | the machine has been in the dark and humid for a long time, with dust all over the sky, oil and other chemical liquid corrosion, as well as the production personnel moving the machine without authorization, it is easy to cause machine problems. In fact, if we deal with these problems in a timely manner, then our machine service life will definitely be much longer The machining accuracy and performance will be as good as new for a long time, the loss will be greatly reduced, the replacement frequency of parts will be reduced, and a lot of time and cost will be saved.

Basic process of CNC machining parts

1. High speed CNC processing product analysis, through product analysis, we should obtain certain composition information and some specific processing requirements. 2. Graphic design the graphic design should be based on the detailed analysis of the product. For example, for the processing of the seal, we should determine the font, text size, seal type by analyzing the processing requirements. Computer gong processing | Dongguan high-speed computer gong processing | Dongguan mold processing | Dongguan Mechanical parts processing | CNC processing 3. High speed CNC processing process planning through the analysis of the appearance and processing requirements of the workpiece products in the early stage, each processing step is reasonably established from the overall processing situation. 4. In fact, the process of path generation is to realize the process planning through software, and optimize the tool path by setting parameters. 5. After the path simulation path is generated, we generally have no intuitive sense of its final performance on the machine tool. Here we can check the possible problems through path simulation, thus reducing the actual processing scrap rate. The general inspection focuses on the effect of workpiece appearance, whether it is overcut or undercut, and whether the process planning of the path is reasonable. 6. High speed CNC machining path output path output is a necessary step of software design and programming on the machine tool. Through the path output, the relationship between the two can be established by the intermediate reference. The main components of high-speed CNC computer gongs mould show that 1. Synthetic resin of high-speed computer gongs is the main component of plastics, and its content in plastics is generally 40% – 100%. Because of its high content, and the nature of resin often determines the nature of plastic, so people often regard resin as a synonym for plastic. Computer gong processing | Dongguan high speed computer gong processing | Dongguan mold processing | Dongguan machine parts processing | CNC processing. For example, PVC resin and PVC plastic, phenolic resin and phenolic plastic are confused. In fact, resin and plastic are two different concepts. Resin is a kind of raw polymer, which is not only used in the manufacture of plastics, but also the raw material of coatings, adhesives and synthetic fibers. In addition to a small part of plastics containing 100% resin, most plastics, in addition to the main component resin, also need to add other. 2. The function of lubricant is to prevent the plastic from sticking to the metal mold during molding, and to make the surface of plastic smooth and beautiful. Commonly used lubricants are stearic acid and its calcium magnesium salt. In addition to the additives mentioned above, flame retardant, foaming agent and antistatic agent can also be added into the plastics. Substance. 3. High speed computer gongs mold filler also known as filler, it can improve the strength and heat resistance of plastics, and reduce the cost. Numerical control machine tool processing, such as adding wood powder into phenolic resin, can greatly reduce the cost, making phenolic plastics one of the cheapest plastics, while significantly improving mechanical strength. The fillers can be divided into organic fillers and inorganic fillers, the former such as wood flour, rags, paper and various fabric fibers, and the latter such as glass fiber, diatomite, asbestos, carbon black, etc. 4. Colorants colorants can make plastics have a variety of bright and beautiful colors. Organic dyes and inorganic pigments are commonly used as colorants in Dongguan high-speed computer gongs processing. 5. Plasticizers plasticizers can increase the plasticity and softness of plastics, reduce brittleness, and make plastics easy to process. Plasticizers are usually organic compounds with high boiling point, which are miscible with resin, nontoxic, odorless, light and heat stable, and phthalate esters are the most commonly used. For example, in the production of PVC plastic, computer gong processing, Dongguan high-speed computer gong processing, Dongguan mold processing, Dongguan Mechanical parts processing, CNC processing, if more plasticizer is added, soft PVC plastic can be obtained; if the plasticizer is not added or less (the dosage is less than 10%), the rigid PVC plastic is obtained. 6. In order to prevent the synthetic resin from being decomposed and damaged by light and heat in the process of processing and using, and prolong the service life, the stabilizer CNC should be added into the plastic

Advantages of CNC machine tools over ordinary machine tools

The advantages of CNC machine tools are as follows:

1. Processing efficiency, saving processing time.

2. Work intensity. After the workers have finished programming, they can go to drink tea after the first piece is qualified.

3. Reduce the number of waste products. As long as the first piece is qualified, the processed parts will generally be qualified.

4. High safety, the farther the workers are from the processing equipment, the lower the probability of accidents.

For effective metal cutting, machining materials, cutting tools and cutting conditions are the three main factors. These determine the processing time, tool life and machining quality. Cutting conditions must be selected reasonably for economical and efficient processing methods.

The three elements of cutting conditions: cutting speed, feed and cutting depth directly cause damage. With the increase of cutting speed, the point temperature will rise, resulting in mechanical, chemical and thermal wear. If the cutting speed is increased by 20%, the tool life will be reduced by 1 / 2.

Back feed conditions and tool wear are kept to a minimum. But feeding behind, cutting temperature rise, wear. It is less than the effect of cutting speed. Cutting depth has no effect on cutting speed and feed, small cutting depth, but cutting material in hardened layer will also affect tool life.

According to the user’s processing material, hardness, cutting conditions, material selection, feed and cutting depth, the cutting speed is used.

Based on the selection of the most suitable process conditions, these factors are selected. Regular life and stable wear are the most ideal conditions.

However, in practice, the selection of tool life and tool wear, through machining size, surface quality, noise reduction, heat and so on. Under certain processing conditions, it is necessary to study according to the actual situation. Difficult to machine materials such as stainless steel, heat-resistant alloy, can use coolant or choose a good rigid blade.

Reasonable selection of cutting tools

1。 Rough rotation, should choose high strength, good durability knife, in order to meet the large car turning, feedback.

2。 The essence of automobile is to select high precision, durable and good cutting tools to ensure the machining accuracy.

3。 Reduce the conversion time and knife convenience, should try to use machine knife and machine clip blade.

Select fixture

1。 General fixture should be selected to clamp workpiece as much as possible, and special fixture should be avoided;

2。 Positioning error is reduced by coincidence.

Determine the processing route

Machining path is the part of tool path and direction relative to each other in the process of exponential control.

1。 It should be able to meet the requirements of machining accuracy and surface roughness;

2。 Shorten the processing route as far as possible and reduce the idle travel time of the tool.

Machining route and allowance

Introduction of CNC machining power input unit and power control part

There are two lights on the power supply of the computer gongs processing center unit. One is the power indicator light, which is green; the other is the power alarm light, which is red. The power supply unit here includes power input unit and power control part.

First of all, we should know that when the power supply of Dongguan mold machining center cannot be connected, if the power indicator (green) is not on. The fuses F1 and F2 of the power supply unit have been blown. This is due to high input voltage, or the components of the power supply unit itself have been damaged.

The input voltage is low. Please check the voltage entering the power supply unit. The allowable voltage value is ac200v + 10%, 50Hz ± 1Hz. The power supply unit is not good, there is element damage in it. The power indicator light is on, and the alarm light is also gone, but the power supply cannot be connected. Dongguan machine parts processing at this time because the power on (on) conditions are not satisfied. By the following switching circuit, the power supply conditions are as follows:

There are three conditions for the power supply of Dongguan large CNC machining center: first, the source on button is closed. Second, the power off button is closed. Third, the external alarm contact is opened.

The alarm light of power supply unit of Dongguan large CNC machining center is on: the fuse of 24 V output voltage is fused, and + 24 V voltage is used on 1.9 “display screen, as shown in the figure below. Check whether + 24 V is short circuited to the ground.

Mold processing technology

Mold processing refers to the processing of forming and blank making tools, in addition to shear mold and die-cutting mold. In general, the mold is composed of upper mold and lower mold. The steel plate is placed between the upper and lower dies to form the material under the action of the press. When the press is opened, the workpiece determined by the shape of the die can be obtained or the corresponding waste can be removed. Parts as small as electronic connectors and as large as automobile dashboard can be molded with molds. Progressive die is a set of mold which can automatically move the workpiece from one station to another, and get the molding parts in the last station.

Precision machining

Today, metal processing, or hardware processing, are special machinery and equipment, easy to work, and much more efficient than manual work, if there is no mechanical equipment, the number of manual work is not able to keep up with the development of today, today’s machinery and equipment can be said that all industries have been throughout, packing machine, packaging machine, folding machine, crane, computer gong Processing | Dongguan computer gongs processing | Shenzhen computer gongs processing | mechanical parts processing | Guangzhou computer gongs processing | forklift trucks and other equipment, in today’s can say that the use of such equipment |!!!

When stopping the precision machining, if the data selected are not awesome enough, it may cause the parts to be processed can not meet the needs of the mechanical equipment, because in this way, the condition of material request must be clearly known when stopping processing.

If is to the metal material stop processing, then, should see its hardness how kind, in many metal material, stainless steel is the hardest, and cast iron is slightly second, copper hardness under cast iron, and aluminum hardness is the lowest, so, workpiece to hardness request high should choose stainless steel, and request low should choose aluminum.

1. First of all, we should understand the hardness request. The higher the hardness request of some equipment used by the central government, the better. However, this kind of ordinary hardness request is only for the processing of the workpiece. If it is processing data, then, computer gong processing, Dongguan computer gong processing, Shenzhen computer Gong processing, mechanical parts processing, Guangzhou computer gong processing, the hardness should not be too hard, Otherwise, the data may be too hard and affect the normal operation of the machine.

2. Then, to see the detailed role of processing parts, if it is used in some high-temperature industries, then the selected material must be high-temperature resistant material, and used in some other industries, then, according to the industry request to select the appropriate material line.

Matters needing attention in processing various aluminum plates

According to the different processing technology, it can be divided into cold rolling and hot rolling.

According to the different thickness, it can be divided into thin plate and medium plate. In GB / t3880-2006 standard, the thickness less than 0.2mm is called aluminum foil. More commonly used brands: pure aluminum plate, strip. Foil. Thick plate, stretch tube. Squeeze the tube. Type. Great. Cold working bar is mainly used in the situation where high corrosion resistance and formability are required, but the strength requirement is not high, such as chemical equipment, marine equipment, railway tank car, conductive material, instrument material, welding rod, etc.

3003: plate and strip. Foil. Plate. Stretch the tube. Squeeze the tube. Type. Great. wire rod. Cold working bar, cold working wire, rivet wire, forging, heat sink material. It is mainly used for processing parts that need good molding performance, high corrosion resistance, or good weldability, such as computer gongs processing, Dongguan computer gongs processing, Shenzhen computer gongs processing, mechanical parts processing, Guangzhou computer gongs processing, or workpieces requiring both these properties and higher than 1 * * alloy strength, such as tanks and tanks for liquid transportation, pressure tanks, storage devices, heat exchangers , chemical equipment, aircraft fuel tank, oil duct, reflector, kitchen equipment, washing machine cylinder, rivet, welding wire. Aluminum clad 3003 alloy: plate, thick plate, stretch tube. Extruded tube plate, 3004, extruded pipe plate, etc. As long as the extruded tube is used in all aluminum can body, the requirements are higher than 3003 alloy parts, chemical products production and storage device, sheet metal processing parts, building baffle, cable duct, sewer, various lamp parts.

Aluminum clad 3004 alloy: plate, thick plate is mainly used for building partition, baffle, sewer, industrial plant roof 5052: plate, thick plate, foil, tensile pipe, cold working bar, cold working wire rod, rivet wire rod. This alloy has good formability, corrosion resistance, weldability, fatigue strength and medium static strength. It is used for manufacturing aircraft fuel tank and oil pipe , as well as the sheet metal parts of traffic vehicles and ships, instruments, street lamp bracket and rivet wire. 6061: plate, thick material, stretch tube. Extruded tube, bar, profile, wire, conduit, rolled or extruded structural section, cold worked bar, cold worked wire, rivet wire, forging. All kinds of industrial structural parts with certain strength, corrosion resistance and high weldability are required, such as pipes, bars and profiles used for manufacturing trucks, tower buildings, ships, trams, railway vehicles, furniture, etc.

According to the different metal elements contained in aluminum plate, aluminum plate can be divided into nine categories, that is, nine series. The following is a brief introduction.

1、 The 1000 series represents 1050 1060 1070 series aluminum plate, also known as pure aluminum plate. In all series, 1000 series belongs to the series with the most aluminum content. The purity can reach 99.00%. Because it does not contain other technical elements, computer gong processing | Dongguan computer gong processing | Shenzhen computer gong processing | mechanical parts processing | Guangzhou computer gong processing | so the production process is relatively simple and the price is relatively cheap, which is the most commonly used series in conventional industries. At present, most of the 1050 and 1060 series are in circulation in the market. The minimum aluminum content of 1000 series aluminum plate is determined according to the last two Arabic numerals. For example, the last two Arabic numerals of 1050 series are 50. According to the international brand naming principle, the aluminum content must reach 99.5%, and the top is the qualified product. China’s aluminum alloy technical standard (GB / t3880-2006) also clearly stipulates that the aluminum content of 1050 is 99.5%. Similarly, the aluminum content of 1060 series aluminum plate must reach more than 99.6%.

2、 2000 series aluminum plate represents 2A16 (Ly16) 2A12 (LY12) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, among which copper element content is the highest, about 3-5%. The 2000 series aluminum plate belongs to aviation aluminum material, which is not often used in conventional industry. At present, there are few manufacturers of 2000 series aluminum plate in China. The quality cannot be compared with that of foreign countries. At present, the imported aluminum plate is mainly provided by Korean and German manufacturers. With the development of China’s aerospace industry, the production technology of 2000 series aluminum plate will be further improved.

3、 3000 series aluminum plate represents 3003 3003 3A21. It can also be called antirust aluminum plate. The production process of 3000 series aluminum plate in China is excellent. The 3000 series aluminum plate is mainly composed of manganese. The content is between 1.0-1.5. It is a series with good antirust function. Conventional application in air conditioning, refrigerator, car bottom and other humid environment, the price is higher than 1000 series, is a more commonly used alloy series.

4、 The 4000 series aluminum plate represents 4a01. The 4000 series aluminum plate belongs to the series with high silicon content. Generally, the silicon content ranges from 4.5% to 6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance. Product Description: it has the characteristics of heat resistance and wear resistance.

5、 The 5000 series represents the 5052.5005.5083.5a05 series. 5000 series aluminum plate belongs to the common alloy aluminum plate series, the main element is magnesium, the magnesium content is between 3-5%. It can also be called aluminum magnesium alloy. Its main characteristics are low density, high tensile strength and high elongation. In the same area, the weight of aluminum magnesium alloy is lower than other series. Therefore, it is often used in aviation, such as aircraft fuel tank. It is also widely used in conventional industry. The processing technology is continuous casting and rolling, belonging to the hot rolling aluminum plate series, so it can do oxidation deep processing. In China, 5000 series aluminum plate belongs to the more mature aluminum

6、 The 6000 series represents 6061, which mainly contains magnesium and silicon. Therefore, it concentrates the advantages of 4000 series and 5000 series. 6061 is a cold-treated aluminum forging product, which is suitable for applications requiring high corrosion resistance and oxidation resistance. Good usability, excellent interface characteristics, easy coating and good processability. It can be used in low-pressure weapons and aircraft joints. 6061 general characteristics: excellent interface features, easy coating, high strength, good usability, strong corrosion resistance, computer gong processing in Dongguan, computer gong processing in Shenzhen, mechanical parts processing in Guangzhou. Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, ship accessories and hardware, electronic accessories and joints, decorative or various hardware, hinge head, magnetic head, brake piston, hydraulic piston, electrical accessories, valves and valve parts.

7、 7000 series represents 7075, mainly containing zinc. 7075 aluminum plate is stress relieved, and will not deform and warp after processing. All super large and super thick 7075 aluminum plates are detected by ultrasonic wave, which can ensure no sand hole and impurity. The high thermal conductivity of 7075 aluminum plate can shorten the forming time and improve the working efficiency.

Its main feature is high hardness, high strength aluminum alloy, which is commonly used to manufacture aircraft structure and futures. It requires high strength, strong corrosion resistance of high stress structural parts, mold manufacturing. At present, China’s production technology needs to be improved. Computer gong processing | Dongguan computer gong processing | Shenzhen computer gong processing | mechanical parts processing | Guangzhou computer gong processing (our company once had a foreign enterprise put forward the problem of uneven annealing of domestic 7075 aluminum plate, resulting in inconsistent surface and internal hardness of aluminum plate).

8、 The more commonly used 8000 Series is 8011, which belongs to other series. In my memory, the aluminum plate mainly used for bottle cap is also used in radiator, most of which are aluminum foil. Not very often.

9、 9000 series belongs to spare series, and science and technology is so developed now. In order to cope with the emergence of aluminum plate containing other alloy elements, the international aluminum plate and strip Federation specially indicates that 9000 series is standby series, waiting for another new variety to appear to fill the gap of 9000 series.

NC machine tool processing method

CNC machining classifies robots according to the motion track of CNC lathe

(1) Point control CNC lathe processing robot. The CNC lathe robot of CNC equipment can only control the moving parts of the lathe from one position to another accurately, that is to say, only control the value of the end of the travel coordinate, without any reduction in the process of moving, Computer gong processing, Dongguan computer gong processing, Shenzhen computer gong processing, mechanical parts processing, Guangzhou computer gong processing, the moving speed and path between the two related points depend on productivity.

In order to locate accurately on the basis of as high productivity as possible, the movement between the two related points is first to move quickly to the new position, and then slow down the 1-3 stage, let it slowly locate the point, so as to ensure its positioning accuracy.

(2) Point line control CNC lathe processing robot. This kind of NC lathe robot processing, not only to control the position between the two related points, but also to control the movement speed and route between the two related points.

Its route usually consists of straight lines parallel to each axis. The difference between the control and the point of NC lathe robot is that when the moving parts of the machine tool move, it can be processed along an axis direction (generally it can be cut at 45 ° oblique line, but not any slope linear cutting). The auxiliary function is the position control of the CNC lathe robot, for example, Improve spindle speed control, computer gong processing, Dongguan computer gong processing, Shenzhen computer gong processing, mechanical parts processing, Guangzhou computer gong processing, feed processing cycle, tool selection, and other functions.

(3) Contour control CNC lathe processing robot. The control device of this kind of CNC lathe can control two or more coordinate axes continuously at the same time.

In the process of machining, we should not only control the starting point and the end point, but also control the speed and position of each point in the whole processing process, so that the CNC lathe robot can process complex shaped parts according to the drawing requirements. Its auxiliary functions are also relatively complete.

CNC machining is classified according to CNC device

(1) Hard wire CNC lathe robot processing (commonly known as ordinary CNC, namely NC). The input, interpolation and control functions of the system are realized by integrated circuits or discrete components.

Generally speaking, CNC lathe robot is different, its control circuit is also different, so the universality of the system is poor, because it is all composed of hardware, so the function and flexibility are poor. This system was widely used before the 1970s.

(2) Flexible wire CNC lathe robot processing (also known as computer numerical control or computer numerical control, namely CNC or MNC). This system uses medium, large-scale and super large-scale integrated circuits to form numerical control equipment, or uses microcomputer and special integrated chips, such as computer gong processing, Dongguan computer gong processing, Shenzhen computer gong processing, mechanical parts processing, Guangzhou computer gong processing. Its main CNC functions are almost completely realized by software. For different CNC lathe robots, only different software needs to be compiled, And hardware is almost universal.

So it has flexibility and adaptability, and it is easy to produce in batch. The quality and reliability of the system are improved by modularization of software and hardware. Therefore, the modern CNC lathe robot all uses the numerical control device.

CNC machining is classified according to the process use

(1) General CNC lathe robot processing. Compared with the traditional lathe processing, this kind of NC lathe robot processing has CNC turning, milling, boring, drilling, grinder and other mechanical processing methods. The possibility of this kind of CNC lathe robot processing technology is similar to that of ordinary machine tools, but it can process complex parts.

(2) CNC lathe robot processing. This kind of NC lathe robot processing is developed on the basis of ordinary NC lathe robot processing.

In general, CNC lathe robot is equipped with a tool library (can accommodate 10-100). The equipment composed of cutting tools and automatic tool equipment uses automatic tools to change CNC lathe robot (also known as multi-step or boring and milling machining center, CNC lathe robot is usually called machining center), Computer gongs processing, Dongguan computer gongs processing, Shenzhen computer gongs processing, mechanical parts processing, Guangzhou computer gongs processing CNC lathes, robot processing development direction further automation and efficiency.

(3) Multi coordinate CNC lathe robot processing. Some complex shape parts can not be processed by three-dimensional CNC lathe, such as propeller, aircraft surface parts processing, need more than three-dimensional comprehensive movement to process the required shape.

Then the multi coordinate CNC lathe robot is used to process the robot. Its characteristics are that the number of control axes of CNC equipment is more, and the structure of lathe is also more complex. The number of coordinate axes usually depends on the processing technology requirements of the parts to be processed.
