CNC lathe processing is a kind of high precision and high efficiency automatic machine tool, which uses digital information to control the displacement of parts and tools. So what do you need to pay attention to when processing CNC lathe? Let’s have a simple understanding:

1. Pay attention to the choice of cutting parameters

The cutting speed, feed rate and cutting depth of CNC Lathe will directly lead to tool damage. With the increase of cutting speed, the tool tip temperature will rise, which will cause mechanical, chemical and physical related wear. When the cutting speed is increased by 20%, the tool life will be reduced by 1 / 2. The influence of feed rate on tool wear is smaller than that of cutting speed, but when the feed rate is large and the cutting temperature rises, the tool wear will be greater. Although the influence of cutting depth on the tool is not as great as the cutting speed and feed rate, when the cutting depth is small, the hard layer of the material to be cut will also affect the tool life.

1. Focus on tool selection

1) In rough turning, the tool with high strength and good durability should be selected to meet the requirements of large back cutting and large feed rate. CNC programming UG communication Q group: 304214709, want to learn NC programming, get no taste of learning raw materials plus this group Oh

2) When finishing turning, the tool with high precision and good durability should be selected to ensure the machining accuracy.

3) In order to reduce the time of tool change and simple tool setting, machine clamping tool and machine clamping blade should be selected.

CNC machining

1. Pay attention to the selection of fixture

1) Although the general fixture is used to clamp the workpiece, the special fixture is prevented;

2) Parts positioning datum coincide to reduce positioning deviation.

1. Pay attention to the affirmation of processing route

Machining route refers to the moving track and target of tool relative to parts in the process of NC lathe machining.

1) The machining accuracy and surface roughness requirements shall be guaranteed;

2) The processing route should be reduced to reduce the tool idle travel time.

In the process of NC lathe processing, we should pay attention to the above four concerns. Only by choosing the most appropriate NC lathe processing method can we improve the processing efficiency and accuracy of NC lathe processing.

The above is CNC lathe processing need to pay attention to, hope to help you.

The precision of hardware parts almost determines the quality of the product. The more precise the hardware parts are, the higher the precision requirements will be. So what are the factors leading to the machining accuracy of hardware parts? Let’s have a brief understanding:

One factor is the poor machining accuracy of the parts themselves. Generally speaking, if the dynamic deviation between shafts is not adjusted well during installation, it may also be because the shaft drive chain changes due to wear, which will affect the accuracy of the parts. Generally speaking, it is advisable to adjust the compensation amount from the beginning in order to check the accuracy caused by the deviation of this variety. If the deviation is too large and even if an alarm occurs, it is necessary to check the servo motor to see if its speed is too high.

The two factors are that the overshoot during the operation of the machine tool will also affect the processing accuracy. It is possible that the acceleration and deceleration time is too short, and the appropriate lengthening of the transition time. Of course, it is also very likely that the link between the lead screw and the servo motor is loose.

The three factors are the roundness out of tolerance caused by the linkage of the two shafts, the axial deformation of the circle caused by the mechanical failure, the compensation error of the screw clearance of the shaft, or the deviation of the shaft positioning, which may affect the precision of the detailed parts.

These are the factors that lead to the accuracy of hardware parts processing, I hope to help you.

Careful hardware processing is to process raw materials (stainless steel, copper, aluminum, iron, etc.) into a variety of high-density parts by lathes, milling machines, drilling machines, polishing machines, etc. according to the customer’s drawings or samples, such as: screws, motor shafts, mold car parts, fishing gear accessories, dog bones. What are the factors affecting the repeated positioning error? Here we are simple Explain it

1. The installation deviation of workpieces in the flow between different machine tools: when turning from ordinary machine tools to numerical control machine tools in the process of careful hardware processing, it is necessary to install them from the beginning, so that the repeated positioning deviation of workpieces cannot be prevented. If EDM is also required, the repeated positioning deviation will be increased.

CNC machining

1. Workpiece repeatedly clamping deviation on the same machine tool: when using ordinary machine tool to process metal parts carefully, if several surfaces need to be processed, several clamping and installation are required. Such repeated positioning deviation will be the sum of repeated installation deviation.

The above are the factors that affect the repeated positioning error. I hope it can help you.

Details? I believe many people are very surprised, because we generally only say what matters to pay attention to? Details are generally less noticed. Many users are like this, but Xiaobian here to remind you that the quality of a product, the success or failure is often determined by some small details, I believe you have heard this sentence, so when doing things, pay more attention to some small details is certainly not wrong, so let’s understand what details should be paid attention to when machining?

(1) The designed process specification shall ensure the processing quality of machine parts (or the assembly quality of the machine) and meet the technical requirements specified in the design drawing.

(2) It is necessary to make the technological process have higher productivity and put the products on the market as soon as possible.

(3) Try to reduce manufacturing costs

(4) Pay attention to reduce the labor intensity of workers to ensure the safety of production.

The above points are the matters needing attention in machining. For more information, please visit our website

In the current industrial industry, hardware processing is widely used, so the utilization rate is still relatively large, but we all know that these molds will wear after a long time of use, which will lead to some failure problems in the later work and use process. At this time, our maintenance work can play a very good role, so let’s learn how to maintain the hardware processing mold?

1. After using the hardware mold for a long time, we will find that it is necessary to grind the edge. After grinding, the edge surface needs to be demagnetized again. It can not be magnetic, otherwise it is easy to block.
2. Check the fastening parts of the hardware mold and check whether the fastening parts are loose or damaged. If there are such cases, the method should be taken to replace the parts with the same specification; check whether the screws and fixed pins are loose, and whether they will jump out to burst the mold. If there is any looseness, lock them with a wrench.
3. In the process of using the die, the punch is easy to break, bend and gnaw. The punching sleeve is generally gnawed. The damage of punch and punch sleeve also needs to be replaced with parts of the same specification.
4. Check the tightness of the guide device, add lubricating oil to prevent the mold from overheating and scuffing; conduct anti rust treatment for the non production hardware mold.
5. During the maintenance of pressing parts and unloading parts, attention should be paid to check whether the accessories of each part are damaged, and repair and update the damaged parts.

The above points are the maintenance methods of hardware processing molds. Good maintenance of molds can well extend our service life, which has many advantages, so we need to do a good job of maintenance. Today we will talk about it.

During the working period, we certainly want to improve our work efficiency. Of course, these are based on the premise of ensuring the product quality. Then, if we want to improve the work efficiency, we should think about the method in the process of work. The modern processing is to be able to improve the production. If the processing table can not meet the requirements of use, in the production process It will be affected to some extent.

In the process of mechanical processing, due to the increasing speed of modern high-speed cutting, in order to adapt to the processing method, then only to reduce the radius of the tool, improve the moving speed of the main bearing of the machine tool. Meet the use requirements in the process of processing, improve the quality of use.

For the mold in the production process, need to achieve high precision, high stability and high speed processing requirements. Only in this way can we improve the cutting ability of the machine tool in the process of cutting and ensure the effect of machining. The above is to improve the machining skills, want to learn more information, welcome to visit our website for detailed understanding.

In the process of production, there will be a lot of faults, but some of them are unavoidable, so we should prepare some methods to deal with them when we are working. So, under casting of die castings is also a common problem. What are the causes of under casting of die castings?

1. The filling condition is poor, and there is irregular condensed metal in the under cast part;

When the pressure is insufficient, the metal in the active front solidifies too early, resulting in under casting at the corner, deep concave, thin wall (even thinner than the average wall thickness) and cylindrical hole wall. The results show that the mold temperature is too low, the alloy pouring temperature is too low, and the location of the inner gate is not good, resulting in large moving resistance.

1. It is difficult to set up the part of overflow system because of gas obstruction and lubrication on the surface of under cast part, which makes it difficult to set up an overflow system. When molten metal moves, turbulent flow is violent and gas entrapment occurs.
2. There is residue in the cavity of plastic mold

The amount of coating or spraying method is improper, resulting in local coating deposition.

When filling, the metal will run into the metal when filling. After the casting is pulled out, it can not be brought out completely and the flake is clamped on the gap. When the sheet metal (the thickness of the metal sheet is the size of the gap) is more convex on the surrounding mold surface, the height of the projection will be changed into the wall thickness of the casting under the condition of closing the mold, so that the future casting will have a groove penetrating (for the wall thickness). This penetrating groove is a special form of under casting. This kind of under cast phenomenon often occurs in the case of deep cavity composed of mosaic.

These are the reasons for the under casting of die castings

How to improve the machining finish of CNC lathe? Let’s have a simple understanding:

1. If the position of large-scale CNC lathe is uneven, it will cause a sensation and affect the brightness of workpiece processing. Therefore, to ensure the stability of large-scale CNC lathe processing, we can better improve the brightness of large-scale CNC lathe processing.
2. Although the spindle is prevented from vibration at high speed, it will greatly affect the brightness of the workpiece.
3. Despite the choice of high quality coolant.
4. Although choose sharp and wear-resistant tools.
5. The chip removal groove should be opened well, even if the chip is not smooth, which may cause the workpiece scratch and affect the brightness of the workpiece.
6. Match the spindle speed and feed speed of the lathe.

The above is to improve the CNC lathe processing finish method, hope to help you

We all know that no matter what the equipment is, there are many matters needing attention in the operation. The purpose of this is to better ensure our work effect, reduce the occurrence of faults and ensure the quality of products. These matters needing attention are basically easy to ignore in our daily work, but sometimes they cause us some troubles. So the following with the small make-up to understand the hardware processing in the operation must pay attention to what matters?

1、 All employees should check whether their clothes meet the work requirements before entering the work. During operation, it is necessary to concentrate on the operation, and it is strictly prohibited to chat and cooperate with each other. The operator should not operate under the state of irritability and fatigue, so as to avoid accidents and ensure the safety of operation.

2、 Before the machine works, check whether the moving part is filled with lubricating oil, and then start and check whether the clutch and brake are normal, and run the machine tool at idle speed for 1-3 minutes. It is strictly forbidden to operate in case of mechanical failure.

3、 When replacing the mold, the power supply should be turned off first, and the moving Department of the punch should stop running before the mold can be installed and debugged. After installation and adjustment, manually move the flywheel for two times to check whether the upper and lower dies are symmetrical and reasonable, whether the screws are firm, and whether the blank holder ring is in a reasonable position.

4、 Only when all other personnel leave the mechanical working area and take away the sundries on the worktable, can the power supply be started to start the machine.

5、 After the machine is started, one person will transport materials and operate the machine. Other people are not allowed to press the electric building or step on the pedal switch board, nor can they put their hands into the mechanical working area or touch the moving parts of the machine with their hands.

6、 When off duty, the power supply should be turned off and the finished products, leftovers and sundries should be sorted out to ensure the clean and safe working environment.

The above six points are the hardware processing in the operation of the need to pay attention to the matter, although it is some very small matters, when we have achieved the effect is very good, so today’s small editor to talk about here, want to know more information, welcome to visit our website for detailed understanding.

Friends who have not contacted this line may not know. When we go to understand the market price, we find that the quotations of many businesses are different. If you don’t know your profession, you don’t know why, so you may have a big head when you make a choice. But as long as we know how to calculate the price of hardware parts processing, we will know how to choose.

1. First look at your drawings and technical requirements
2. There are differences in materials and labor in different places, and there is a big price difference in some places
3. General parts are calculated according to material cost + processing cost + profit. The processing cost depends on the process. The price of different processing equipment is of course different. Some are calculated according to working hours (turning time, grinding time, etc.), and some are calculated according to working procedures (such as how much is a folding plate for a knife, how much is a common drill hole, etc.)
4. There is also a problem of quantity. A large quantity is certainly cheap. If it is a single piece, even if it is a small piece and the materials are not retailed, you should calculate the price of the whole board! For example, if you say 0.3, the manufacturer does not use it frequently. If you only buy one or two pieces of materials, if you only buy one board at a time (such as 1220 * 2440), you will be wrongly spent on the material cost.
5. If the parts processing factory can solve the problems of the processing factory itself, of course, there is no problem. If the processing factory itself has some processes to be outsourced, the price will be correspondingly increased. If you are outsourcing, it means that you have been outsourced twice! So you should find the right one to find what they can do and what they are good at
