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 bett...

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 o...

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.
