How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

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

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.
