Working principle of slow wire processing

by
 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

by
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

by
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,

A large number of automobiles, agricultural machinery and other oil-using machines cannot be completely updated

cncmachining December 25, 2021

 

Enterprises lack a product development mechanism that integrates scientific research and application, lack systematic scientific research capabilities, and cannot conduct product application research in response to market needs. The central research institution is out of touch with the production enterprises, and the scientific research is not well integrated with the market orientation and user requirements. There is a big gap between the personnel system and incentive mechanism compared with foreign enterprises.

Foreign companies enter China in order to seize. First, recruit talents and realize the localization of talents. Domestic companies are facing severe situations such as brain drain and aging. The deep-seated problem of the existing gap is still a system and mechanism problem. In order to implement the resolution of the Fifth Plenary Session of the 15th Central Committee of the Party Central Committee, it is necessary to adhere to the market-oriented and enterprise-oriented spirit. The modern enterprise system with clear powers, separation of government and enterprise, and scientific management enables enterprises to truly become the main players in market competition with independent operation, self-financing, self-development, and self-discipline.

Only by truly solving the system and mechanism problems, can we effectively deal with the fiercer market competition after China’s entry into the WTO. Market Positioning According to China’s national conditions, the original large number of automobiles, agricultural machinery and other oil-using machinery cannot be completely updated in a short period of time. Therefore, the medium-range oil market has a large capacity.

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. Our automotive precision shop and experts deliver confidence. We have perfected the art of producing large component volumes with complete JIT reliability, backed by the quality and long-term reliability our customers expect.
