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

There is no strict production standard for fake and inferior auto parts


For users, even if safety, environmental pollution and energy saving are not considered, counterfeit and inferior auto parts are very troublesome. Counterfeit and inferior parts do not have strict production standards and perfect inspection and testing methods. There are many hidden quality problems, short service life, and the frequency of failures during use is quite high. Failures occur every three days, and minor repairs occur in a few days. Overhaul not only causes certain economic losses to users, but also annoying.

The proliferation of counterfeit auto parts in the market is harmful to no benefit. It has caused huge economic losses and reputation losses to the national management departments, manufacturers, sellers and consumers, and seriously threatens the safety of people's lives and properties. In this case, counterfeit and inferior parts can make money by using other people’s brands and markets. With little input, high output, and small money, you can make a lot of money. The high profit makes some people stunned and unscrupulous to delve into how to produce fake and inferior auto parts. Some small businesses, handicraft workshops, and cottage industry workers do not work hard on the technology and quality of the products, but spend their money on opening up some relationships, finding some low-tech auto parts production, and then selling them under the brand of others. Under-brand companies with a little technical strength are targeting those imported auto parts or key parts with higher profits. Since the sales of fake and inferior auto parts are quite flexible, no matter how bad the quality is, there is no worries that there will be no sales. There is a huge distribution network of fake and shoddy cars all over the country, everywhere, everywhere, where there are cars, there are fake and shoddy auto parts.
