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 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.

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.
