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

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

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.
