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

Introduction of KOVAR parts

KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR  machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stress,

Function analysis of diaphragm clutch

Lingfeng’s automobile clutches not only made a splash in the domestic market, but also began to enter the international market, breaking the situation that domestic automobile clutches only exported a single driven disc assembly. When the heat treatment production line introduced by Lingfeng Company had not yet been put into production, foreign businessmen had already proposed an annual supply of 300,000 diaphragm springs. The export business is still under negotiation. Chongqing Lingfeng Company has taken a gratifying step in the field of diaphragm elastic clutch production. The company is working with the friction material industry at home and abroad to develop high-quality child-free friction materials, and plans to cooperate with the Japanese automotive clutch professional manufacturer Daikin (DK) to jointly develop and produce more types of diaphragm spring clutches and A new generation of Yuhe device that has been used in developed countries? Hydraulic torque converter.

Faced with the rapid development of China's automobile industry and the upcoming historical challenge of "return to customs", Lingfeng Company, based on the current annual output of 150,000 sets of clutches, puts forward the goal of the second phase of technological transformation, and strives for the "Ninth Five-Year Plan". “At the end of the year, the goal of achieving an annual output of 450,000 sets will be achieved. At that time, the high-quality diaphragm elastic clutch produced continuously from the assembly line of Lingfeng Company will strongly support and meet the needs of the development of the domestic automobile industry. The management of motor vehicle repair parts in Shenyang does not count as military vehicles. In addition to the parts required for repairing vehicles, a total of 500 million yuan will be required for parts. It is sold to other places about 300 million yuan, with a total sales of nearly 1 billion yuan. The average gross profit margin of enterprises is above 15%, and it is profitable to exclude expenses and taxes. This is one of the reasons for the rapid development of the auto parts market in Shenyang. There are many large and medium-sized enterprises in Shenyang, and there are many fleets. In order to turn stock parts into working capital, auto parts stores are opened one after another.

The automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry.
