Working principle of slow wire processing

by
 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

by
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

Introduction of KOVAR parts

by
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR  machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stress,

With the development of non-state-owned bearing factories, bearing production has expanded rapidly

cncmachining February 02, 2022

Promote the improvement of the overall level of bearing quality. With the development of non-state-owned bearing factories, bearing production has expanded rapidly, and market competition is very fierce, especially for low- and medium-grade ball bearings. The supply exceeds demand. In order to occupy the market, they have worked hard on quality and set precision indicators. The internal control standard is higher than the current national standard, and the precision reserve rate of middle and low-grade bearings is improved.

Develop high-quality precision bearings to replace imports and fill the domestic gap. Produce high-quality bearings to enter the international market. At present, the bearing market has turned into a stage of quality competition, and the result will inevitably promote the improvement of the overall quality level of the entire industry. Improve the ability to resist risks after China’s entry into the WTO, certain mechanical and electrical products will cancel import controls and tariff reductions, foreign products will soon enter the domestic market, and the bearing industry will be greatly affected.

However, with the development of non-state-owned bearing factories, especially the development of private bearing factories in recent years, the overall production capacity, technical level, management methods and sales channels of the industry have been greatly improved. In addition, the private bearing factories' New concepts and fast shifts. Once the conditions are ripe or needed, they will spontaneously or horizontally unite under the guidance of the government to form a large group to improve market competitiveness. All these can improve the ability to resist risks after joining the WTO.
