CNC manufacturers talk about the matters needing attention in CNC aluminum processing

Some customers often ask what problems should be paid attention to when processing CNC aluminum parts, which is very familiar to Shenzhen shengyuanda Hardware Products Co., Ltd., which has rich experience. What is the specific content?

As we all know, aluminum alloy beam, frame aluminum profile and frame aluminum profile of general equipment need deep processing before they can be put into use. This process needs to go through sawing, drilling, tapping, milling and so on. Customers can choose machines according to the precision of aluminum parts and aluminum alloys.

Let’s learn about CNC machining

1. The speed of white steel knife should not be too fast. When the workpiece is too high, it should be sliced with different length of knife.

2. When taking wcut, if you can take finish, don’t take rough. When the shape of the light knife, first roughing, then polishing, when the workpiece is too high, first smooth the edge, then light the bottom.

3. After roughening with a big knife, use a small knife to remove the remaining material to ensure that the allowance is consistent. The plane should be processed with flat bottom cutter and less ball cutter, so as to reduce the processing time.

CNC aluminum parts processing

4. Set tolerance reasonably to balance machining accuracy and computer calculation time. The tolerance is set to 1 / 5 of the allowance for roughening and 0.01 for smooth knife.

5. The four corners of the calibration plane should be smooth. Try to take simple knife path, such as shape, groove, single side, less walking around the height. Do more procedures to reduce the time of empty knife. Think more and reduce the chance of making mistakes. Make more auxiliary lines and auxiliary surfaces to improve the processing condition.

6. Where the slope is an integer, use a slope cutter to process, such as pipe position. In order to avoid making a clear cutting tool in the previous or after machining.

7. Establish a sense of responsibility and check each parameter carefully to avoid rework. Diligent in learning, good at thinking, and continuous progress. When milling non flat surface, use ball cutter more, use less end knife, do not be afraid to connect knife; small knife angle cleaning, big knife finishing; don’t be afraid of patching, proper patching can improve the processing speed and beautify the processing effect.

The above seven items are the matters needing attention in the process of CNC aluminum parts processing summarized by Shenzhen shengyuanda Hardware Products Co., Ltd. We hope customers will pay more attention to avoid accidents and affect the normal operation of the equipment when they are put into use.

How to arrange CNC machining sequence of high precision aluminum parts

The production of hardware products is inseparable from CNC processing technology. The novices who are not familiar with the industry or are just beginning to know little about CNC processing technology. Shenzhen shengyuanda Hardware Products Co., Ltd. is committed to CNC processing of high-precision aluminum parts, which has strict requirements for processing procedures. How to reasonably arrange CNC processing sequence of high-precision aluminum parts in the operation of the author in this industry for many years What about it?

In the CNC processing workshop of aluminum parts, everyone has different working positions, but we must be familiar with and keep in mind the processing principles, such as the principle of first priority and then the secondary principle. What is the specific meaning?

Operators should first process the main working surface and assembly base surface of the parts, so as to find out the possible modern defects on the main surface of the blank as soon as possible. The secondary surface can be interleaved after the main machined surface is machined to a certain extent and before Zui final finishing.

Of course, there are certain rules in the processing of different aluminum parts, which need to follow the principle of surface first and then hole. The plane outline size of box and bracket parts is large, and the plane is generally processed first, and then the hole and other dimensions are processed. This arrangement of processing sequence, on the one hand, it is stable and reliable to use the processed plane for positioning; on the other hand, it is easy to process holes on the processed plane, and can improve the machining accuracy of holes, especially when drilling holes, the axis of holes is not easy to deviate.

Of course, the CNC machining process of high-precision aluminum parts should follow the principles of first coarse and then fine, first near and then far, and the principle of base surface first is not introduced here. In a word, after selecting CNC processing methods and dividing working procedures, the main content of the process route is to reasonably arrange these processing methods and the sequence of processing procedures. Only orderly processing can improve the processing quality and production efficiency of parts.

What clamping methods are used in CNC machining of aluminum frame

As an important link in CNC machining of aluminum frame, some novices only know a little about CNC machining. What Xiaobian wants to say is that the basic principle of clamping is horizontal length and vertical short. Next, senior operators will explain to you what are the lower clamping methods?

Splint clamping is specifically used to code the splint on the CNC processing table, and the workpiece is locked on the splint with screws. It is suitable for clamping with insufficient height, and can also be applied to workpieces with large processing force or general medium and large workpieces, and the effect will be good.

The clamping of cutting tools refers to that the diameter is more than 10 mm, and the clamping length is not less than 30 mm; when the diameter is less than 10 mm, the clamping length should not be less than 20 mm. The clamping of the tool should be firm to prevent the phenomenon of hitting the tool or directly inserting into the workpiece.

CNC machining of aluminum frame

The clamping height of vise should not be less than 10 mm. It is necessary to specify the clamping height and processing height when processing workpieces. The processing height should be about 5mm higher than the vise plane to ensure the firmness, so as not to damage the vice. The clamping height is related to the size of the workpiece. When the workpiece is large, the clamping height increases accordingly.

Code iron clamping is mainly used when the workpiece is large and the clamping height is not enough, and it is not allowed to lock the wire at the bottom. This kind of clamping needs to be clamped twice. First, the four corners should be coded, and then the other parts should be processed, and then the four sides should be coded to process the four corners. During the second clamping, do not let the workpiece loose, code first and then loosen. You can also code both sides and process the other side.

From the above several clamping methods, it is not difficult to find that the different processing methods are different. In the CNC machining process of aluminum frame, we need to select according to the specific workpiece.

Scheme of reducing surface damage of aluminum profile by CNC machining

Aluminum profile surface damage is a problem that many aluminum alloy CNC processing enterprises will encounter. How to prevent or reduce aluminum profile surface damage? As the surface damage of aluminum profiles will greatly reduce the production rate of aluminum profiles and increase the production costs of many enterprises, we find that this problem has become a hot topic for most enterprises.

In order to solve the problem of surface damage of aluminum profiles, we must find out the causes and find solutions. What causes the surface damage of aluminum profile during CNC machining? Let’s talk about the human factors and the reasons for the CNC processing equipment of aluminum alloy.

Human factors mainly refer to the damage caused by some unfamiliar operators dragging profiles on the pendulum bed. There is also in the process of transportation, the improper placement of aluminum profiles, making the profile friction or extrusion between the formation of damage.

If the damage is caused by processing equipment, it is not ruled out that the mold cavity or work with dust and debris, so that the hardness of the working belt is low, causing aluminum profile scratch in the extrusion process.

If there are aluminum chips in the CNC machining track or swing table, the aluminum profile surface may be scratched and the yield will be affected.

In short, there are many factors that affect the surface scratch of aluminum profile, so how should we deal with it?

For the damage caused by human factors, we should strengthen the management of personnel, aluminum profiles need to be handled with care to avoid random dragging phenomenon. For the problems in the processing process, the author suggests that we regularly check the CNC machining track and swing table of aluminum alloy, and remove the impurities and aluminum chips on them. When placing, there should be a gap in the middle and lay more felt. Prevent collision and friction

How much does computer gong process cost an hour?

What is computer gong processing? At first glance, many people will feel very confused, what is a computer gong? What is computer gong processing used for? The layman must know nothing about this. In fact, computer gongs are familiar with CNC milling machines. Computer gongs are just the name of Hong Kong. Later, they were introduced into the Pearl River Delta of the mainland and were known by people.

Computer gongs processing is the so-called machining center, also known as CNC or CNC machine tools, is an automatic machine tool with program control system. Through its own control system, the program with control code or other symbol instructions can be processed logically. In this process, decoding is carried out, and finally the machine tool can operate and process parts.

How much does computer gong process cost an hour?

If the price of the gongs is not very high, it will not be very expensive to process the parts in different areas.

For example, in Shenzhen, using vertical computer gongs to process Cr12MoV specifications, 220 × 190 × 86 two curved surface processing depth less than 1 mm, the material of the following parts is about 60-100 yuan / hour.

How to judge whether the aluminum profile processed by CNC for aluminum frame is qualified or not

As we all know, the quality of aluminum profiles sold in the aluminum profile market is uneven, resulting in many unqualified aluminum profiles in the market. Some bad merchants, in order to seek profits at all costs, led to the aluminum profile market sales chaos, consumers do not know how to judge whether the aluminum profile is qualified.

Formal and professional CNC processing manufacturers of aluminum frame will strictly select materials to ensure product quality, because only by improving the quality can they have good reputation. Naturally, there is no need to worry about marketing. So now the market situation, aluminum profile unqualified performance in what aspects?

In order to reduce the thickness of the aluminum oxide film, the thickness of the oxide film is not qualified, resulting in the reduction of the corrosion resistance of the aluminum film. The film thickness of aluminum profile processed by CNC should not be less than 10 μ M.

CNC machining of aluminum frame

Shortening the sealing time will result in poor sealing, which will affect the corrosion resistance and pollution resistance of aluminum profiles.

The reason for the disqualification of form and position tolerance is that the extrusion press is too old, or the CNC processing equipment of aluminum frame is relatively outdated, which will lead to the poor cooperation between aluminum profile and parts, and even worse, it can not be used.

The manufacturers familiar with CNC processing of aluminum frame all know that the thinner the wall thickness of aluminum profile, the lower the cost. The wall thickness of qualified profile needs to be measured with caliper, which can not exceed or be lower than the tolerance range, which is the so-called unqualified wall thickness.

If the products processed by CNC aluminum frame are unqualified, it will seriously affect the interests of the company. Don’t say that any unqualified products can be sold. From a long-term point of view, this is harmful to others and not beneficial to oneself. If aluminum frame CNC processing enterprises want to develop, they must guarantee the quality of products and do a good job in after-sales service.

What are the advantages and disadvantages of CNC machining

Many people have heard of CNC lathe and CNC technology, but they don’t know about CNC machining of aluminum alloy. What does CNC machining mean?

In fact, CNC machining of aluminum alloy is a method to control the movement and processing process of machine tool by using digital information. The machine tool that uses numerical control technology to implement machining control, or machine tool equipped with numerical control system, is called numerical control (NC) machine tool.

With the continuous progress of science and technology, the development of modern CNC machining technology has tended to be high-speed, high-precision, high reliability, multi-function, composite, intelligent. This processing technology has been widely used in various fields. What are the advantages and disadvantages of CNC machining of aluminum alloy? The author takes you to analyze it together!

CNC machining of aluminum alloy

First to understand the shortcomings of this processing technology, in fact, the machine tool equipment is expensive, requiring maintenance personnel to have a high level.

Compared with the disadvantages of CNC machining of aluminum alloy, this processing method shows more advantages of its own, and also reflects its own value in major industries. Specific advantages:

① It can machine complex surface which is difficult to process by conventional method, and even can process some parts which cannot be observed.

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 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.

On the whole, the emergence of CNC processing of aluminum alloy brings great convenience to our life, and also improves the production efficiency of various industries.

Modernization process of CNC machining center with aluminum cavity

With the rapid development of modernization, CNC machining of aluminum cavity is paid more and more attention. People gradually begin to change the traditional ideas. People put forward various new requirements on the surface performance and appearance of aluminum cavity CNC machining. For example, when large area electroplating is used on the related products of aluminum cavity CNC processing, because people do not like the color of light, like another color, so they develop a new type of aluminum cavity CNC machining Aluminum cavity CNC processing products.

The modernization process of aluminum cavity CNC machining is tortuous and long. We all know how important the CNC machining of aluminum cavity is for industrial production. With the development of modern science and technology, the equipment industry is moving towards the extreme manufacturing direction: on the one hand, the equipment is becoming more and more tall, on the other hand, the products processed are more and more sophisticated, the processing technology is also more and more complex, and the integration of production technology is also higher and higher.

CNC machining of aluminum plate with aluminum cavity

In order to meet the demand of future products, many enterprises in the industry have begun to replace the traditional CNC machining center with aluminum cavity CNC machining center. Different from the traditional CNC machining center, the aluminum cavity CNC machining center is generally divided into grades according to the number of shafts. Those below the three axis CNC machining center are low-grade, the three to five axis CNC machining center are medium and high-grade, and those above five axis CNC machining center are high-grade.

After years of development and generations of hard work, China’s aluminum cavity CNC machining center industry has made a major breakthrough in the production of traditional CNC machining center. At present, it has become the third largest production country of aluminum cavity CNC machining center in the world. This is the result of a strong country, which is the credit of all the people working in the front line and the hard work of everyone. We are worthy of being powerful and have strong technology, which has changed the modernization process of CNC machining center for aluminum cavity in China.

With the rapid development of the modernization process of CNC machining center for aluminum cavity, more and more mechanical manufacturing equipment are constantly changing to high-speed, high-precision, high-efficiency and high-intelligence, and the demand for high-speed CNC machine tools in various industries is increasing day by day. In the design and manufacture of high-speed CNC machine tools, CNC machining of aluminum cavity is particularly critical.

In CNC machining of aluminum cavity, selecting reasonable cutting parameters is the most economical and effective machining method. The operator should select the cutting speed according to the material to be processed, hardness, cutting state, material type, feed rate, cutting depth, etc. The most suitable processing conditions are selected on the basis of these factors. Regular and stable wear is the ideal condition for service life.

How to determine CNC processing route

Operation technicians need to make preparations when using CNC aluminum plate machining center. Of course, each operator has his own set of skills. Here, the author would like to say that both novice and experienced personnel should be prepared for use. What are the specific contents?

CNC machining of aluminum plate

The tool used in the inspection should be consistent with the specification allowed by the machine tool. The maximum tool length, maximum tool weight and total tool weight of CNC machining center for aluminum plate are determined.

Check whether the tool used is worn or damaged, sometimes it should be replaced immediately. Check for obstructions around machinery and control systems.

Some moving parts are lubricated with grease. Before working, check whether the machine tool has reached the time specified on the lubrication indicator plate, and supplement it in time.

Safety awareness must have, check whether the control system is closed. Whether the control switches are in good condition. Whether someone is in the mechanical danger area.

How does the operator determine the CNC processing route when using the aluminum plate CNC machining center? I would like to share with you:

CNC machining of aluminum plate

First of all, we need to understand what CNC processing route means? It refers to the path that the turning tool moves from the tool setting point (or the fixed origin of the machine tool) until it returns to the point and ends the processing program. It includes the path of cutting and the path of non cutting empty stroke such as cutting in and cutting out. In order to determine the CNC processing route, the following principles must be followed:

1. Shorten the processing time and reduce the processing time.

2. Ensure the accuracy and surface roughness of the workpiece to be processed.

3. For some repeated programs, subroutines should be used to simplify the workload of numerical calculation and the processing program.

In a word, in order to ensure the aluminum plate finish machining, we must do the preparatory work, and ensure that the aluminum plate CNC machining center processing route is correct.
