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

Improve auto parts sales economy

The auto parts market is generally affected by the big market, and demand has been flat after the second half of last year. However, the auto parts market is growing in demand with the increase in car ownership, which is everyone’s consensus. The national auto parts industry target has been set, measures are gradually introduced, supporting policies are gradually implemented, and the auto parts distribution system is further deepening reforms, and the agency system is in the ascendant, which provides a good economic environment for the development of the auto parts market. According to low standards, the total national demand for repair parts is 50 billion yuan, the six provinces and one city in East China are 14 billion yuan, the provinces and cities where the 10 provinces and cities are located are 19 billion yuan, and the user demand in Shanghai is 1.5 billion yuan. Based on the above analysis of the situation, the seminar believes that the first half of 1996 was a turning point for the start of the market, and the sales of automobiles and accessories in the first quarter became more difficult. We cannot sit back and watch the loosening of the macro economy, let alone miss the opportunities that appeared in the business activities at the beginning of the year. We should be full of confidence, muster the courage, face the reality, make the best use of the situation, grasp the business as soon as possible, and seize the fleeting signs of rebound in sales. , Put up the sales of cars and accessories.

In terms of vehicle sales, it is necessary to maintain and develop the original resource channels, consolidate and straighten out the integration of industry and trade, special dealership and agency business; and organize the resources of marketable vehicles and agricultural vehicles according to market demand, and make advances based on the needs of the market. , Strengthen research and after-sales technology, maintenance, and supply services. Adopt various preferential and flexible methods to expand sales, and at the same time open up the old car sales market, take the operation of old cars as a new economic growth point, and prevent assembled cars, eliminated cars, and inferior cars from entering the market. For high-quality products, implement unified distribution, share agency, increase batches, and increase grades, strive for the largest discounts from the factory, and strive for economies of scale. Be flexible and adaptable in terms of methods. Whether wholesale or retail, we must strive for market share with brand-name varieties, high quality, preferential prices, and high-quality services. 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. 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.
