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

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

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

Quality Inspection Center for Auto Repair Parts

The China National Automobile Industry Corporation or the China Automobile Trade Corporation establishes a national automobile repair parts quality inspection center to be responsible for the organization of the automobile repair parts product inspection in the auto parts sales system. This center selects several provinces (municipalities, districts) auto parts companies in the country with better conditions to establish sub-centers, deploy inspection personnel, inspection equipment and methods, and specifically engage in inspection work of repair parts products. According to the key automobile parts, safety parts and products that affect automobile technology, economy, power and other quality issues, a range of inspection varieties and a certain number of variable manufacturers are delineated, and each branch center carries out regular inspection work throughout the year according to the division of labor. , The test varieties are not duplicated, and the test samples are drawn from the goods purchased in batches by the distribution units in the system, and samples can also be provided by the distribution units in the system who have doubts about the quality of a certain product.

The testing center announces the quality status of the manufacturer once a year. With the approval of the superior, this testing center is the authoritative organization for the quality appraisal of auto repair parts. All dealers in the auto parts sales system must obey its decision on the quality of repair parts. Distributors in the auto parts sales system shall not distribute the products of manufacturers that have not been tested or failed to pass the test within the scope of the specified inspection side. For products with quality problems tested, the testing center has the right to notify all distribution units in the sales system to stop purchasing from the manufacturer. To enter or re-enter the parts sales system market for new products, products from manufacturers outside the catalog, and products from manufacturers outside the catalog, they must pass the quality inspection and obtain the quality certificate issued by the testing center before they can be sold in parts sales. The right to sell the system. Those who have obtained high-quality products from the state and ministry can enjoy inspection-free; provincial high-quality products are only inspected once. 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.
