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

Minimal lubrication for metal cutting

At present, with the global economic development slowing down and China’s manufacturing industry is facing great challenges, it is necessary for companies to get out of the predicament. In the fierce market competition, all members of Doppsey firmly believe that based on high-quality products and services, helping users reduce manufacturing costs and improve production efficiency is the foundation of enterprise development. Technological progress, solving customer needs and market demands are the driving force behind the research and development of new products, and the application of innovative technologies and new processes has found a breakthrough in the bottleneck period of enterprise development.


Today, most machinery manufacturing companies still use cutting fluid cooling and lubrication. With the application of new materials and coating technologies, dry machining has emerged. Although dry machining eliminates the need for lubrication systems, the quality of workpiece processing and the use of cutting fluid lubrication exist Some gaps, while the dust during dry processing will affect the environment.


Doppel focuses on the research of lubrication in the machining process, and has introduced a micro-lubrication system through the research of cutting fluid lubrication processing, dry cutting processing, and quasi-dry processing. The realization of quasi-dry cutting makes up for the defects of low cutting fluid lubrication efficiency, high energy consumption, easy oil leakage and environmental pollution; it also avoids the impact of poor chip removal, poor surface quality and dust on the environment caused by dry cutting The problem.

Minimal lubrication, through the built-in channel and external specially designed nozzle, the generated micron-level oil mist particles are accurately sprayed on the contact surface of the cutting edge and the workpiece. The friction of the moving contact point is reduced, and the processing debris is purged and discharged by the jet of high-pressure airflow, which avoids the fibroids of the debris on the processing surface. Due to the use of very little lubricating oil, there will be no residual oil on the workpiece surface, which reduces the subsequent cleaning of the workpiece.


With the improvement of environmental protection requirements and people’s recognition of micro-lubrication technology, micro-lubrication technology will be widely used. Doppelsey is willing to work with you to better explore and make progress in the process of practice.
