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

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

Oil-air lubrication is beneficial to the performance of electric spindle

 The electric spindle runs at a high speed, and the good lubrication of the bearing is an important index to ensure its normal operation.Therefore, matching a suitable electric spindle lubrication system is very important.
The lubrication-related factor that affects the running accuracy of the electric spindle is the heating of the electric spindle.The internal heat source of the electric spindle comes from two aspects: 1. The heating of the spindle bearing; 2. The heating of the built-in motor of the electric spindle.
To solve the heating of the motor, the stator of the motor needs to be cooled, which can be achieved by circulating water cooling to take away the heat of the motor; to solve the problem of heating of the spindle bearing, it is necessary to remove the heat generated by the bearing operation in time.Traditional thin oil lubrication is to transport a large amount of lubricating oil to achieve intrusive lubrication. At the same time, the lubricating oil takes away the heat.This kind of lubrication method has disadvantages. First, it wastes a lot of lubricating oil. Second, the friction between lubricating oil molecules and the pipeline during the cycle of lubricating oil generates a lot of circulating heat, which causes the oil temperature to rise. At this time, the lubricating oil Not only can it not have a good cooling effect, but it will also cause the temperature of the bearing to rise, which is not conducive to the performance of the spindle bearing.Therefore, eliminating the generation of frictional heat between molecules in the liquid has become the key to solving the problem.practice shows that,Oil-air lubricationThis situation can be avoided fundamentally.First of all, oil-air lubrication provides a small amount of lubricating oil to meet the amount of lubricating oil required by the bearing.Secondly, oil-air lubrication will not produce heat due to friction of lubricating oil molecules, and at the same time, clean compressed air will take away the heat generated by the bearing and keep the spindle running at a stable temperature.This can effectively solve the problem of thermal deformation caused by temperature rise.
