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,

Interpretation of bamboo fiber

Bamboo fiber is a cellulose fiber extracted from naturally grown bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has good air permeability, instant water absorption, strong abrasion resistance and good dyeability. It has natural antibacterial, antibacterial, anti-mites, deodorant and anti-ultraviolet functions.

Among all natural fibers, bamboo fiber ranks first in the five major fibers in terms of moisture absorption and release properties and air permeability, and its far-infrared emissivity is as high as 0.87, which is much better than traditional fiber fabrics, thus conforming to the characteristics of thermal comfort. At a temperature of 36°C and a relative humidity of 100%, the moisture regain of bamboo fiber exceeds 45%, and its air permeability is 3.5 times stronger than that of cotton. It is known as the “breathable fiber” and also called the “fiber queen”. “.

Bamboo fiber products have natural antibacterial, bacteriostatic, and bactericidal effects, because bamboo contains a unique substance, which is named “bamboo kun”, which has natural antibacterial, anti-mite, anti-odor, and anti-insect functions. Observed under a microscope, bacteria can multiply in cotton, wood and other fiber products, while the bacteria on bamboo fiber products not only cannot survive for a long time, but also disappear or reduce in a short time. The bacterial mortality rate reaches 99% within 24 hours. above. The new findings of the Japanese authority increased the added value of this product. The results were confirmed by the China Cotton Textile Product Quality Supervision and Inspection Center and the Shanghai Institute of Microbiology, Chinese Academy of Sciences. The result of bacteria multiplying thousands of times).
