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

Improve the technical level of China’s automobile emissions

The civilian investment project of China North Benz heavy-duty vehicle technology transformation project passed the national inspection and acceptance, forming an annual production capacity of 6,000 vehicles. It marks that China has built its third heavy-duty vehicle production base in Baotou, following the Sinotruk Group and Dongfeng Motor Corporation. Yuejin Automobile Group Corporation and Italian Fiat Group Iveco Company registered Nanjing Iveco Co., Ltd. The Ministry of Machinery issued the “Ninth Five-Year Plan” for the Control of Emissions from Automobile Products. The implementation of this plan will greatly improve the technical level of China’s automobile emissions.

The eighteenth meeting of the Eighth NPC Standing Committee appointed Bao Xuding, the former deputy minister of the Ministry of Machinery Industry, as the Minister of the Ministry of Machinery Industry. The technical appraisal expert group and the localization verification group composed of the Automobile Industry Department of the Ministry of Machinery Industry and the Tariff Department of the General Administration of Customs have verified that the localization rate of Changan Alto cars has exceeded 60%, which has reached the second-level differential tax rate requirement of preferential tariffs stipulated by the state.

With the approval of the China Securities Regulatory Commission, 36.8 million new shares of Shenyang Songliao Automobile Co., Ltd. were issued online at a fixed price on the Shanghai Stock Exchange. The shares of “Songliao Automobile” issued this time are called “Military stocks.” The Sino-US joint venture, Dongfeng Cummins Engine Co., Ltd., with a joint investment of US$78 million, was established in Nangfan. The opening ceremony of the joint venture Qingqi Suzuki Motorcycle Co., Ltd. was grandly held in Jinan High-tech Development Zone 1.

At the Shanghai International Automobile Exhibition, Shenlong Automobile Co., Ltd. officially launched Fukang’s new models of AL (luxury) and AG (basic) 1.6-liter EFI cars. The National Bureau of Technical Supervision approved the conditions for the opening of the gas vehicle maintenance industry “GB/T16739” began to be implemented. The “conditions” put forward higher levels of investment in testing equipment and technology for auto maintenance companies. The safety inspection line of Beverly Cars has passed the national requirements, and the owners of auto maintenance are guided to pay more attention to the acceptance. From now on, Beverly Cars will enjoy the protection of the environment for new cars.
