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

Introduction of KOVAR parts

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,

The heat treatment process of auto parts consumes a lot of energy

 

The heat treatment process of auto parts consumes a lot of energy, so it is necessary to work to reduce the energy consumption in each treatment stage, which includes furnace improvement, carburizing process control, quenching medium, cooling rate, etc. However, the operation of these processes is directly related to the properties and hardenability of the processed steel with different compositions. In order to meet the requirements of advanced heat treatment technology, various types of steel have been studied from smelting. The improvement of these steels and related technology has greatly improved the performance and processing productivity of auto parts.

The chemical composition and hardenability of steel are the key factors to obtain the best heat treatment effect for auto parts. In order to obtain high-quality small-modulus gears in automotive products, it is necessary to carefully control the surface and core hardness of the gears. The development of direct heat treatment of steel, as well as the development of oxygen steelmaking furnace technology, continuous casting and rolling technology and other steelmaking technologies, have improved the selection of key points for precise control of chemical items. Microstructure control, reliability, application, size, reduce carburizing time. Hardenability, carbon potential, high performance of mixed heat treatment of quenching medium, composite heat treatment, furnace design can be economical and effective, heat source and load basin, insulation materials for the production of a variety of products, gas generated in the furnace body, furnace body size, linear mechanism Atmosphere control carburizing time is reduced, furnace body, carbon irrigation, maximum residual stress, carbon potential, carbon in steel, basic atmosphere carbon gradient, best quenching nitrogen, vacuum, plasma quenching technology, small deformation, quenching orange, fixture Structure, maximum residual stress, effective quenching cooling rate of quenching medium and carbon gradient fixture, use of temperature and quenching rate mixing technology heat energy, thermochemical reaction anti-rust surface film formation.
