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

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

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.
