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

The benefits of micro-lubrication of engraving machine

During the milling and working process of the engraving machine, a large number of small debris will be generated. These debris can be seen everywhere in the work site. The traditional lubrication method will cause the debris to adhere to the surface of the workpiece, which will seriously affect the quality of engraving. At the same time, most traditional engraving machines are used A large number of emulsion spraying methods achieve lubrication and cooling. The disadvantage of this method is that processing any light cutting parts also requires a large amount of emulsion circulating spraying. On the one hand, it causes a waste of emulsion; on the other hand, it accelerates the aging of the equipment structure. After aging, the amount of emulsion leaking to the ground increases. When cutting tools rotate at high speeds, the emulsion will also be sprayed to the surrounding area. Over time, environmental pollution is serious. Workers’ skin and respiratory system are affected by the emulsion in such an environment, and their health is also affected. There will be potential injuries, which is also an important factor in the loss of operating technicians. The application of micro-lubrication technology has significantly improved the environment. After the product is processed, it saves a lot of cleaning work and reduces labor costs and energy consumption.

 

The engraving machine adopts the Doppel micro-lubrication system to achieve quasi-dry cutting. The system can perform lubrication and cooling of the processing tools and workpieces and remove debris according to the actual needs of the work during the milling process of the engraving machine. Any emulsion leakage, there is no excessive oil on the surface of the workpiece, thus reducing the subsequent cleaning work, saving manpower and material resources, quasi-dry cutting avoids the harm of workers’ skin damage, reduces the staff turnover rate, reduces training costs, and improves efficient. At the same time, there is no oil leakage, the equipment and ground environment are clean, and zero pollution is achieved.
