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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

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

Talking about the construction of auto parts supply network

 

To establish a corresponding supply network, first of all, we must choose a good business partner, mainly based on the other party’s economic strength, supply capacity, parts source channels and creditworthiness. As the saying goes: “Shop around and don’t lose money.” Through long-term observation and business exchanges, introducing a competitive mechanism, and the survival of the fittest, we have identified several business units as fixed supply outlets. For accessories that are not ordered directly from the manufacturer, they are all supplied by these outlets. Secondly, these outlets are required to achieve high-quality, competitive prices, and be responsible for quality issues to the end. Third, these outlets can implement high-quality services, agency transportation or door-to-door delivery, which saves the trouble of lack of manpower and can request goods at any time. Fourth, regular settlements are adopted for these outlets, usually one to two months. This makes full use of inventory and reduces capital occupation.

Starting from the national conditions and factory conditions, boldly explore new ways to do a good job in the localization of imported parts. Our company's K256 Clas car is an old-fashioned truck produced in the former Soviet Union. This type of vehicle has always been a special vehicle for our company's Sanguiqiao Dolomite Mine. The purchase of the necessary parts requires a large amount of foreign exchange if imported from the Soviet Union, and the cycle is very long, which is very uneconomical. We have also made some attempts. We have imported a batch of original Claas parts from the factory contacted by the Ministry of Metallurgy and some units at the Heihe Port. The price is surprisingly high. According to the actual situation, starting from the factory and national conditions, it is completely possible to replace imported ones with domestic ones. In the process of localization, we established business contacts with the designated localization unit of the Ministry of Metallurgy. Now we need more than 97 Klass accessories are domestically produced, which basically meets the company’s production needs and saves foreign exchange.

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.
