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

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

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.
