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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

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

What is five-axis radiator machining?

That day, a university friend who specializes in machinery talked about their skills, because there are still a few in the same class, so all kinds of terms are basically not understood, until the very high-frequency term radiator five-axis machining appears. I just listened with interest. When you see these words, are you thinking, I know the radiator, but what do these seven words mean? If everyone wants to understand such an industry, just keep reading.

The radiator five-axis machining center is also called a five-axis linkage machining center. I think it is unwise to “talk about accuracy out of actual demand”. Suppose you just want to divide a large aluminum block into several smaller pieces and make spare blanks. You have to control the dimensional accuracy within a few wires (1 wire = 10 microns). , Can only be said to be a waste of money. It is inaccurate to “talk about accuracy without the actual machine tool”. Therefore, to say that “the accuracy of a five-axis Cnc Machine tool is higher than that of a three-axis CNC machine tool” is in fact a matter of fact. Let’s take a look at the common classifications of five-axis machining centers.

Several linkage methods have their own characteristics. It is impossible to categorize which is better. You can only say which processing procedure the product you want to produce is suitable for which five-axis machining center to choose.

(1) Five-axis linkage double swing head machine tool

The driving power of the swing coordinate of the double swing head machine tool is small, the workpiece is easy to load and unload, and the coordinate conversion relationship is simple

(2) Five-axis linkage double turntable machine tool

  • (A) The rotating coordinate has enough travel range and good process performance.
  • (B) Due to the limitation of the structure, the rigidity of the swing coordinate is low, which becomes the weak link of the rigidity of the whole machine tool. On the double-turntable machine tool, the rigidity of the turntable is much higher than that of the swing head, which improves the overall rigidity of the machine tool.
  • (C) It is easy to develop into a processing center. Only need to install independent tool magazine and tool change manipulator, but double turntable machine tool turntable coordinate drive power is larger, coordinate conversion relationship is more complicated;

(3) Five-axis linkage, one swing head and one turntable machine tool

The performance of a swing head and a rotary table machine is between the above two.

It is such a technology with a sense of science and technology invented by the human brain, which has been applied on a large scale in our lives. We often see products, but technology may not be so easy to access, but after reading this article, even if we don't touch it, we still have a general understanding of our current new technology.
