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

Instruct and appraise the quality of auto repair and auto parts

 

Quality technical experts conduct evaluations, follow-up services, and accept complaints on the quality of auto repair and auto parts in accordance with national and industry standards. This is the best in the auto repair industry in Jiangsu Province. After China and the United States signed the “Accession to the World” agreement, Jiangsu Zhongda responded quickly to set up a quality appraisal center, issued a “Quality Commitment Letter” to users, and set up quality tracking points. They believe that China’s accession to the WTO is just around the corner, which is both an opportunity and a challenge for Chinese companies.

We must prepare early to be invincible in the future global market competition. Strive for Toyota to get permission to build cars in China, Xiali is about to be reborn. The National Development Planning Commission has approved two development projects recently. One is to invest 100 million yuan to establish Tianjin Toyota Motor Co., Ltd. as a joint venture with Toyota Motor Co., Ltd., and the production will be produced by Tianjin Motor Xiali Co., Ltd. The second is a medium-sized car in the global strategic small car series jointly developed by Japan Toyota Motor Corporation and adopts a common platform. The second is to invest 100 million yuan, based on the one and one in the world strategic small car series newly developed by Toyota Motor Corporation of Japan. , Implemented the Xiali car model replacement project.

At this year's fair, Zhongda's fully automatic computerized car washing machine became the new favorite of the old year. At the International High-tech Achievement Fair held in Shenzhen, the Zhongda gantry-type fully automatic computerized car washing machine attracted much attention. It has become a new favorite for its fast and convenient cleaning, clean and bright, powerful function, wide application range, fast investment recovery and other advantages. The Organizing Committee of the High-tech Fair took the lead in ordering this car washing machine and using it as a long-term car washing machine in the exhibition hall.
