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

The status quo of the development of auto parts circulation enterprises

Although in the current after-sales market, especially in the commercial vehicle after-sales market, some powerful and large-scale distribution companies have appeared, from the perspective of resources, the status of being restricted by the OEM cannot be changed. From the perspective of the market, commercial vehicle manufacturers seem to pay more attention to their special service stations in various places, and some high value-added products are even monopolized by service stations. This is beyond the reach of social dealers. With the integration of vehicle companies’ product resources for their supporting parts companies, the situation that social dealers directly purchase goods through parts companies may also be changed. What makes social dealers more incomprehensible is that.

The market share of    service stations is far less than that of social dealers, but they have always been favored by vehicle companies. How will the social dealership survive in the cracks develop in the future? Is the whole vehicle company only wanting to be independent of the after-sales market with a “service station” model, and what role the vehicle company expects social dealers to play in the after-sales market is plagued by a series of questions Social dealers. At the summit forum organized by the National Commercial Vehicle Parts Production and Marketing Federation, there were more than 1,300 exhibitors at the three major light vehicle OEMs in Futian, Dongfeng, and Jianghuai, and the 65th National Auto Parts Fair in Guangzhou. Among them, there are nearly 80 special exhibitors. , A gathering of well-known brands in the auto parts industry, and a good policy to promote the auto market to attract back in the “National Commercial Vehicle Parts Production and Marketing Federation” carefully organized.

With regard to the “service stations” and social dealers set up by vehicle companies, Tan Quanyu, manager of the spare parts company of Beiqi Foton Automobile Co., Ltd., said that vehicle companies do not favor “service stations”, nor do they neglect social parts dealers. The “service station” is more aware of and cooperating with the management, processes and requirements of the vehicle company, and also has a good understanding of the corporate culture of the vehicle company.
