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

Management of joint ventures and group companies

Several cards in the hands of today’s auto parts salespersons. Many auto parts salespersons like to play these cards: One is the matching cards, that is, most of them appear in the form of matching for a certain automobile manufacturer or a certain OEM. Speaking, there are those with supporting certificates and photos; the second is the joint venture brand, that is, they rely on a manufacturer with a little reputation in the market as a joint factory or branch of a certain factory, and the third is a member brand. That is, it appears as a member of a production group and a sales group, and the fourth is a supervisory brand, that is, it appears in the form of supervision of a certain auto parts company, some of which are supervised by a certain research institute, and some are supervised by a certain industrial university. Some of this kind of producer is unbelievable. For example, some people say that it is supervised by a certain county auto parts company, and people know the company’s situation very well, and they simply don’t have the ability to supervise a certain high-tech product. The user has only one principle, no matter what you are, as long as the quality is excellent and the price is reasonable, you will use it, otherwise you will not recognize those brands.

Strengthen the management of the joint enterprise: the quality of the joint brand. Many joint enterprises take a famous and high-quality product as their leader, and expand the production of famous and high-quality products through joint ventures. However, because some affiliated factories did not produce auto parts, or did not have the ability to produce such famous and high-quality products, as soon as the brand was listed, the products would be produced immediately, and the products produced in this way did not match the name of the famous and high-quality products. Nowadays, many users shook their heads when they mentioned the products of the joint ventures. They were a little bit dubious about the products of the factories that produced famous and high-quality products, and were afraid that they were the products of the joint ventures. The main joint factory should strengthen the management of the joint factory, provide technical training to the personnel of the joint factory, and strictly monitor the quality, so that unqualified products will not leave the factory, so that product quality can be reliably guaranteed, and users can be assured and trusted . Clarify product quality responsibility identification. The State Council promulgated the “Regulations on Quality Responsibility for Industrial Products” in 1986. Quality problems of manufacturers’ products should be resolved through consultation with users in accordance with the “Regulations.” 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.
