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

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

Quasi-dry machining and micro lubrication

With the continuous development of metal processing technology and technological progress, green processing has become more and more popular. The traditional way of using cutting fluid for lubrication and cooling is gradually being replaced by dry cutting technology. Because dry cutting also has many defects for machining, the quality of the processed parts is reduced, the cutting edge wear is accelerated, and the dust affects the environment. The micro-lubrication technology conforms to the market demand. The results of the application of micro-lubrication technology show that the quality of the processed parts is improved, the tool wear is reduced, and many problems caused by dry cutting have been solved. It will also become a definite process technology that matches 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 lubrication technology solves the lack of dry cutting without lubrication. The surface quality of the processed workpiece under dry cutting conditions is improved, and the lack of rapid wear of cutting tools is improved, and the service life is prolonged.


During metal processing, cooling and lubrication is an important aspect related to product accuracy and quality. Under the condition of achieving the same product quality, it is also necessary to consider the control of processing costs, to reduce the overall cost of processing to a greater extent, and to improve production efficiency. For the processing of small parts with good heat dissipation, the cooling 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 resources of over-lubrication and reducing production costs.


With the increase of the government’s environmental protection requirements for 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. Expenses also affect the competitiveness of enterprises.


Doppelt conforms to the trend of green manufacturing in the machinery industry, and continuously introduces trace lubrication products that meet the needs of various machining processes. The application of trace lubrication technology in metal processing will bring more benefits to enterprises. We are willing to welcome the green with you. The era of manufacturing has arrived.
