What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

How to solve the three major welding difficulties in laser cutting processing

Because laser technology has the characteristics of low welding heat input, small effect of welding heat area and resistance to deformation, it has received special attention in the field of aluminum alloy welding. But on the other hand, due to its own defects, there are three major welding difficulties in laser cutting of aluminum alloy. So how to solve it cleverly?

Welding difficulty one: the laser absorption rate of the material is low;

solution:

1. Take proper surface pretreatment process. For example, pretreatment measures such as sandpaper polishing, surface chemical etching, and surface plating. Increase the absorption rate of the material to the laser.

2. Reduce the spot size and increase the laser power density.

3. Change the welding structure so that the laser beam forms multiple reflections in the gap. Facilitate aluminum alloy die casting china

How to solve the three major welding difficulties in laser cutting processing

Welding difficulty 2: easy to produce pores and hot cracks

solution:

1. After many welding experiments and researches, it is found that adjusting the laser power waveform during the welding process can reduce the unstable collapse of pores. Changing the angle of laser beam irradiation and applying a magnetic field during welding can all reduce the pores generated during welding.

2. When using YAG lasers, the pulse waveform can be adjusted to control the heat input to reduce crystal cracks.

Welding difficulty 3: During the welding process, the medical machining of the welded joints decrease;

solution:

Due to the unstable pores produced by aluminum alloy welding, the mechanical properties of the welded joints are caused. Aluminum alloys mainly include three elements: Zn, Mg, and Lv. During welding, the boiling point of aluminum is higher than the boiling points of the other two elements. Therefore, some low-boiling alloy elements can be added when welding aluminum alloy elements, which is beneficial to the formation of small holes and the firmness of welding.

to sum up:

The high efficiency of  laser cutting china of aluminum alloy makes people look forward to its development prospects. Therefore, some researchers continue to develop new technologies such as laser-arc coincidence technology and dual focus technology to improve the stability of the welding process and improve the quality of the weld.
