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

Elimination of Gear Backlash in CNC Machining Feed System

Elimination of Gear Backlash in CNC Machining Feed System   The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on th

Approximate dry machining benefits from minimal lubrication

With the continuous development and technological progress in the field of metal processing, the concept of green processing has become more and more popular. The traditional lubrication cooling method using cutting fluid is gradually replaced by dry cutting technology. Because dry cutting also has defects for machining, it makes the machining quality drop and the cutting tool wears faster. Micro-lubrication technology emerged at the historic moment. The application of micro-lubrication technology improves the quality of machined parts and reduces tool wear. To a large extent, it solves the impact of dry cutting and will gradually become a technology that is compatible with dry cutting. The application of micro-lubrication technology will gradually replace the cooling and lubricating effects of cutting fluid.


The application of oil mist micro-lubrication technology can solve the lack of dry cutting without lubrication, improve the surface quality of processed workpieces under dry cutting conditions, reduce the wear of cutting tools, and extend the service life.


During metal processing, cooling and lubrication is an important aspect related to product accuracy and quality. While the same product quality can be achieved, the overall processing cost should be reduced as much as possible, and the production efficiency should be improved. For the processing of small-sized parts, the parts themselves have good heat dissipation, and the spraying method using a large amount of cutting fluid is undoubtedly a waste of energy. The application of micro-lubrication technology is to provide the amount of lubrication as needed, avoiding the waste of over-lubrication, and achieving controllable and reduced costs.


However, with the increase in environmental protection requirements of industrial enterprises, the impact of the lubrication method of pouring cutting oil on the environment and human health has been paid more and more attention. At the same time, the cost of using cutting oil and the treatment of waste liquid are not small for enterprises. Expenditures also virtually affect the competitiveness of enterprises.


Doppelt adapts to the trend of green development in the machinery industry, and continuously introduces micro-lubrication products that meet the needs of various machining processes. The application of micro-lubrication technology in metal processing will bring more benefits to enterprises. We are willing to welcome the green with you. Revolution of manufacturing.
