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

Comprehensive requirements for the performance of internal combustion engine oil, gear oil, and hydraulic oil

 

As the automobile manufacturing industry continues to improve the transmission device, the ATF standard is required to rise accordingly, and the life span of the transmission system is the same. The main performance requirements of ATF oil are relatively high. The functional requirement is to improve the transmission efficiency of the power; it acts as a hydraulic oil, is a heat transfer medium, prevents wear, rust and corrosion, and lubricates the sliding and rolling surfaces. The characteristic requirements are excellent low temperature performance, oxidation resistance, foam resistance and air inclusion, compatibility with air-sealing cushions, compatibility with other ATF oils, and must be compatible with various friction materials.

ATF oil is a kind of oil with comprehensive performance and excellent quality, which concentrates the comprehensive requirements on the performance of internal combustion engine oil, gear oil and hydraulic oil. ATF oil is a lubricant with *complex formula, *difficulty in preparation, and high technical requirements. Especially today and in the future, the performance requirements of ATF oil are extremely demanding, and there are special requirements for base oils. Hydroisomerized ò, ó type base oils have excellent oxidation stability, and their low temperature performance is far superior to solvent refined oils. Another advantage of hydroisomerized dewaxing base oil is that it can reduce the impact on the friction performance of ATF oil.

ATF oil prepared with isomeric dewaxing base oil also has a certain energy saving effect. Therefore, the isomeric dewaxing base oil is the best component for the preparation of ATF oil, especially suitable for the production of ATF oil. Daqing Lubricant No. 2 Plant has the ability to produce ATF oil, and is currently sending the oil to the Southwest Research Institute for various tests of Dexronó, and will further obtain Allison C-4 certification.
