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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

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

Quasi-dry machining and micro lubrication

With the continuous development of metal processing technology and technological progress, green processing has become more and more popular. The traditional way of using cutting fluid for lubrication and cooling is gradually being replaced by dry cutting technology. Because dry cutting also has many defects for machining, the quality of the processed parts is reduced, the cutting edge wear is accelerated, and the dust affects the environment. The micro-lubrication technology conforms to the market demand. The results of the application of micro-lubrication technology show that the quality of the processed parts is improved, the tool wear is reduced, and many problems caused by dry cutting have been solved. It will also become a definite process technology that matches with dry cutting. The application of micro-lubrication technology will gradually replace the cooling and lubricating effects of cutting fluid.


The application of oil mist lubrication technology solves the lack of dry cutting without lubrication. The surface quality of the processed workpiece under dry cutting conditions is improved, and the lack of rapid wear of cutting tools is improved, and the service life is prolonged.


During metal processing, cooling and lubrication is an important aspect related to product accuracy and quality. Under the condition of achieving the same product quality, it is also necessary to consider the control of processing costs, to reduce the overall cost of processing to a greater extent, and to improve production efficiency. For the processing of small parts with good heat dissipation, the cooling method using a large amount of cutting fluid is undoubtedly a waste of energy. The application of micro-lubrication technology is to provide the amount of lubrication as needed, avoiding the waste of resources of over-lubrication and reducing production costs.


With the increase of the government’s environmental protection requirements for industrial enterprises, the impact of the lubrication method of pouring cutting oil on the environment and human health has been paid more and more attention. At the same time, the cost of using cutting oil and the treatment of waste liquid are not small for enterprises. Expenses also affect the competitiveness of enterprises.


Doppelt conforms to the trend of green manufacturing in the machinery industry, and continuously introduces trace lubrication products that meet the needs of various machining processes. The application of trace lubrication technology in metal processing will bring more benefits to enterprises. We are willing to welcome the green with you. The era of manufacturing has arrived.
