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

The amount of wear between the mating parts is very small

In the process of highway construction, a large number of construction machinery and construction machinery combinations are required. Due to the gradual deterioration of their technical conditions during use, the engine power decreases, fuel consumption increases, exhaust gas exceeds the standard, transmission component gaps increase, and operating mechanisms do not work well. An error occurs in the working device. This is mainly due to the wear of the parts, the structure of the parts, the processing quality of the materials, the working conditions (climate and construction environment), the quality of the fuel and lubricating materials, the reasonable degree of use, the operation methods in the construction, the configuration of the machinery, and technical maintenance Caused by repair quality, etc., we will analyze separately below. Wear and damage of construction machinery parts During the use of the machinery, wear occurs due to the friction between the parts. Under normal circumstances, the wear process of parts is divided into D stages. **The stage is the running-in stage. The surface of the processed parts is rougher before running-in, so the wear is larger. Such as the running-in period of a newly purchased mechanical vehicle. During this period, with the increase of time, the working surface of the parts gradually wears out, so that the fitting clearance between the parts reaches the initial clearance clearance. The second stage is the normal working stage of the parts. After the mating parts are run-in, the surface of the parts is smooth and smooth, and the mating clearance reaches the design standard. During the use of the machine, the amount of wear between the matching parts is very small, and the matching gap grows slowly. The third stage is the accident damage stage. During the use of the machine, due to the increase in the fit gap, impact load is generated, the lubrication conditions of the parts become worse, and the sharp increase in wear may damage the parts and cause mechanical accidents. Mechanical wear Mechanical wear is caused by the friction between the surfaces of the parts. Although the surface of the parts is machined, it is still impossible to be absolutely smooth. When the surfaces of the parts are in contact with each other, they are uneven and easy to embed in each other. When the parts move, the raised metal particles are constantly falling off. When the fit gap increases to a certain extent, the parts will increase due to the impact load, and the lubrication conditions will be destroyed and wear will continue to increase.
