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 bett...

What are the rules for metal stamping die scrap tube?

by
The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th...

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 stre...

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.
