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

Talking about the formation of auto parts trading market


Due to the different administrative affiliations and the coexistence of multiple economic components, there has been a state of excessive, chaotic, and chaotic business outlets in the field of auto parts circulation, which is not conducive to the formation of a professional auto parts trading market, and it cannot adapt to the transportation industry. And the development of the automobile industry. There are too many outlets and competition is desperate. In the field of auto parts circulation where supply and demand are stable, hundreds of business units have soared in a short period of time, and they have been rushed in, eager for profit, lack of management and professional ethics, and abnormal fierce competition will inevitably appear. For example: use “rebates” and “profits” as bait to attract users and expand sales. Irregular competition has seriously damaged the business climate of the industry, and business behaviors such as selling fake products and increasing the rate of difference between purchases and sales without authorization have occurred from time to time.

Excessive business outlets, social inventory of goods is unpredictable. These huge amounts of funds are used for material turnover and inventory, which is not conducive to the development of the automobile industry and has caused a certain degree of blindness. Counterfeit famous brands are sold everywhere, and illegal operations cannot be managed. The phenomenon of counterfeiting of Shanghai’s famous brand products is becoming more and more serious. Violation of the price policy is another important aspect that causes chaos in the auto parts market. The main manifestations are: unauthorized increase in the rate of difference between purchases and sales, and reselling at increased prices. The normal operation of some outlets has been fostered, and the company’s main channel sales market share and market coverage have been increased. Promote the formation of a hierarchical network of auto repair parts market. Strengthen the regulation and management of the auto parts market. After the service company has obtained the administrative power granted by the government department, it adopts the method of management and service to go hand in hand. It not only relies on administrative means, but also sincerely guides the social network on the price and economically supports it. In the past two years, we have done a variety of work and have received certain social effects.
