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,

Auto parts company system reform

For the auto parts company system, it is a prerequisite for the organization of commodity circulation. The National Auto Parts Company's “Eighth Five-Year Plan” work key recommendations suggest that supplementing its own funds and strengthening its strength are an important task in several major work plans. According to statistics, the current self-owned funds of the whole system are around 400 million yuan. The bank loan amounted to 1 billion yuan, and interest payment has become an important burden. In the future, with rising prices, the content of its commodities will continue to decline, which is bound to seriously affect economic efficiency and corporate strength. In the current situation of a small reform and opening up to push companies to the market, failure to do a good job of supplementing corporate funds will greatly weaken their competitiveness. How to replenish funds, state-owned large and medium-sized enterprises can take advantage of the preferential policies given by the state under the current favorable situation of reform and opening up, but this alone cannot meet their needs.

In response to the development trend of the automotive industry product market during the “Eighth Five-Year Plan” period, production and sales have accelerated. Every year, production and sales are growing at a rate of more than double digits. If a company only uses a single channel to increase its own funds, it is far from being able to meet the needs of market development. At present, the country's fiscal revenue is still difficult. Investments are mainly placed on major national capital construction projects. The interest burden on bank loans is heavy and risky, so it is necessary to find another way. On the basis of summarizing the management of the “Fangqiang”, we have carried out several joint-stock system pilot projects that are open to the public. “This is actually to open up a new channel for enterprises to replenish funding sources within the scope of national policy permits. Through the reform and opening up in the past 10 years, the living standards of urban and rural residents have been greatly improved, and the living standards of urban and rural residents have changed from subsistence to well-off. Rural residents. The deposit amount is as high as 900 billion yuan, and the people have about 120 billion yuan in cash on hand. If such a large amount of consumption funds can be converted into production funds, it can not only absorb the large amount of cash in the hands of the people, but also diversify the risks borne by the banks. A solid material foundation for the implementation of the shareholding system. For 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.
