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 vertical lathe has a good effect of micro-lubrication

Micro-lubrication is applied to vertical lathe processing in two application forms: external spray type and internal cooling type. <br /> &nbsp;&nbsp;&nbsp; The external spray type micro-lubrication is easy to install, as long as it does not affect the processing and the movement of other parts, it can meet the requirements. <br /> Internal cooling type micro-lubrication is that the lubricant is sprayed to the cutting area in the form of suspended oil mist particles. The key is to maintain the reliable flow of suspended particles. Therefore, the structure design of the machine tool should ensure the effective transportation of suspended particles The sealing of the channel and the channel is reliable, and the optional fixture and cutting tool should be matched to ensure that the lubricating oil mist particles can reach the cutting area. <br /> &nbsp;&nbsp;&nbsp; Vertical lathes can be used with internal cooling type micro-lubrication and external cooling type micro-lubrication. The micro-lubrication system can be equipped according to the specific conditions of the machine tool. Most vertical lathes do not have internal cooling channels, so external nozzles are often used to deliver MQL oil mist to lubricate the cutting area of ​​the cutting tool. The following is a brief description of its characteristics: <br /> &nbsp;&nbsp;&nbsp; When the lubrication device receives the processing signal, the injection system enters the working state, the lubricating oil is supplied by the micro pneumatic lubrication pump at the set frequency, and the spray is formed at the nozzle The oil mist particles reach the surface of the workpiece. The compressed air at each lubrication point is kept in a constant supply state. When the processing is completed, the lubricating device is powered off and stops working at the same time. The oil supply frequency is adjusted according to the oil film formed in the injection area as the standard. <br /> &nbsp;&nbsp;&nbsp; The system low liquid level monitoring can give an alarm when the oil level is low, and remind the maintenance personnel of the lubrication system that the oil needs to be added. The low liquid level alarm signal can be linked with the machine tool alarm system. <br /> &nbsp;&nbsp;&nbsp; The external spray type lubrication adopts precise metering micro-lubrication technology, which saves oil consumption, and reliably sprays the lubricating oil on the surface of the workpiece and cutting tool in the form of tiny oil mist particles at the terminal. Lubricant film. <br /> 1. Jet-type lubrication can save a lot of oil consumption without causing waste. <br /> 2. Lubricating medium consumption is low, measured in ml/h units; <br /> 3. Oil quantity is accurately measured and supplied accurately; <br /> 4. The system has few moving parts, reliable operation and small maintenance ;<br /> 5. The oil and gas pipeline layout is simple, easy to install and maintain. <br />
