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 progress of automobile manufacturing technology and the stricter environmental protection indicators

The technicality, complexity and particularity of lubricating oil products fully reflect the necessity of lubricating oil technical service work, which is embodied in the following aspects: Lubricating oil is a product with high technical content, and its product development and application research involve petrochemicals and machinery. Professional and other multi-disciplinary fields, cross-professional, cross-industry proficiency in lubricant expertise is not easy; any mechanical design must carry out a reasonable lubrication design, and any application of any kind of oil has problems. However, the lubricating oil market is wide-ranging, with many types of user industries, and users are in a state of dissociation and dispersal. It is necessary to establish a large number of expert service teams; there are many varieties of lubricating oils, and the specifications and grades are complex.

China has formulated lubricating oil classification standards with reference to international standards. Lubricants are divided into 19 categories according to application occasions. Each category 1 oil product is divided into several varieties. For example, E category internal combustion engine oil includes gasoline engine oil, diesel engine oil, railway internal combustion engine oil, and marine cylinder oil. , Medium-speed cylindrical diesel engine oil, two-stroke gasoline engine oil, etc. In the internal combustion engine oil, there are single-grade oil, multi-grade oil, and general-purpose oil. There are about a hundred brands in such a combination. Without certain lubricant business knowledge, it is difficult to choose suitable lubricants; due to the advancement of automobile manufacturing technology And environmental protection indicators are becoming more and more stringent. Lubricants, especially internal combustion engine oil, have become the fastest replacement products in the petrochemical industry. Compared with developed countries, China’s oil grade is quite different. The demand for lubricants in developed countries has a very small span. Only two grades of lubricants coexist in the United States, and only three grades of lubricants coexist in Europe. Taking gasoline engine oil as an example, China has the highest grade SL grade gasoline engine oil. There are also SC and even SA and SB grade gasoline engine oils, with a difference of seven or eight grades. Due to the country's insufficient enforcement of oil quality grades and users do not understand the basic knowledge that upgraded products can replace original oil products, it is difficult to promote new upgraded products and cannot use oil and oil products as in industrialized developed countries.
