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

Mini Lubrication Application of Vertical Car

&nbsp;Minimum lubrication is used in 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 /> The 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 to this is to maintain the reliable flow of suspended particles. Therefore, the structure of the machine tool should be designed to ensure the transportation and transportation of suspended particles. The sealing of 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 />
