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 bett...
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 o...

The current cutting fluid lubrication cooling method is widely used in turning processing. Such lubrication causes relatively large physical injury and environmental impact to the operator and the workshop environment. The processing cost of cutting fluid is also relatively high. Due to the emergence of these problems, the application of micro-lubrication technology in lathes has been promoted. <br /> The amount of back-grabbing, feed, and cutting speed are the main factors that directly affect the quality and efficiency of turning. In order to improve the impact of cutting fluid on the machining environment and on the maintenance requirements of the lathe, it is important to study the application of micro-lubrication technology in lathe cutting. The advantages of micro-lubrication for lathes are: <br />
1. The design cost of the machine tool is reduced, and there is no need to focus on sealing protection, which saves costs. <br />
2. The cutting fluid cooling system is removed to reduce the floor space. <br />
3. It can improve the surface processing quality of the workpiece. <br />
4. Improve processing efficiency. <br /> There are two types of micro-lubrication devices for lathe cutting: oil mist lubrication devices and oil-air lubrication devices. Micro-lubrication is a lubrication method in which vegetable-based trace oil is atomized into micron-sized particles and then delivered to the tip of the knife through an external nozzle or through the internal cooling channel of the knife handle. Oil-air lubrication is a lubrication method in which a very small amount of lubricating oil is accurately metered and then delivered to the nozzle by compressed air. The compressed air is torn into mist particles and sprayed to the cutting part. Because of the low oil consumption, these two lubrication methods can be applied to the micro-lubrication machining of lathe cutting. <br /> Regardless of the lubrication method, compressed air is used as the power, so the pressure and stability of the compressed air directly affect the reliable operation of the lathe cutting micro-lubrication device. The air source pressure of the lathe cutting micro-lubrication system is ideally at 8-10bar. This pressure range can ensure the lubricating oil atomization rate and delivery volume. The response speed from opening the micro device to spraying to the tip of the knife is fast, and it almost arrives with the air source. It has good permeability while being reliable in delivery, which has a good lubrication effect and the effect of suppressing temperature rise. <br />
