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
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

In the world, improving the five-axis processing technology level of product development is an important symbol of the fully automated manufacturing technology level of a developed enterprise producing numerical control equipment. Due to its special technical status, it is an important strategic influence on my country’s aviation, aerospace, and military modern industries, as well as the huge complexity of production technology. Western modern industrial developed countries have always regarded five-axis series CNC control system products as strategic important materials. , And implemented the import and export production license management system.
For decades, people have generally believed that the five-axis processing transmission technology for new products is an important technical means for continuous product processing. However, the CNC five-axis motor-linked material CNC technology is the most difficult to research and develop in the current CNC technology. It integrates CNC computer automatic control, high-performance CNC servo motor drive and precision material processing.
In order to continuously improve the efficiency of verification machining, it is urgently required to completely eliminate the use of traditional “trial cutting method” mechanical verification processing methods. In the five-axis machining of machine tool product development, the workpiece verification and maintenance work of the nc operating program has also become more important, because the mechanical workpieces that usually need to be processed by five-axis Cnc Machine tools are expensive and the tool collision problem is five-axis. Common collision problems in the processing of CNC machine tools: mechanical tools directly cut into other workpieces; mechanical tools are connected to other workpieces through collisions at extremely high moving speeds; mechanical tools and CNC machine tools, fixtures and other machinery within the scope of the five-axis machining process The equipment collides with each other; the mobile tool on the CNC machine tool collides with the fixed parts of the machine tool or other workpieces.
Compared with the new CNC product processing system with three-axis five-machine linkage, from the perspective of production process and workpiece programming, the use of CNC product development five-axis processing machine for complex precision surface products has the following advantages and can be effective Improving the quality of product processing technology and production efficiency can be used to expand the application range of production technology, and it may be used to meet the innovation direction of the development of my country’s composite chemical industry.
