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

Classification, main functions and performance of lubricating oil for heavy-duty vehicles

Classification, main functions and performance of lubricating oil for heavy-duty vehicles At present, lubricating oils for heavy-duty vehicles can be divided into diesel engine lubricating oil according to their purpose (heavy vehicles are mostly diesel engine vehicles, and only diesel engine lubricating oil is introduced here), gear oil and grease Three categories. The main function and performance of diesel engine lubricating oil. The main function of diesel engine lubricating oil, anti-friction effect Diesel engine lubricating oil must be able to reduce the friction of all parts of the engine, prevent excessive wear between the contact points of metal parts, and ensure the normal operation of the engine. Purifying and dispersing effect. Due to the high sulfur content and soot content of diesel fuel during combustion, there are more insoluble components in the engine oil. When the deposits formed by these substances block the engine piston ring, it will affect the normal operation of the engine, so the diesel engine The lubricating oil must have a good dispersing and cleaning effect to prevent the insoluble matter in the oil from forming attached sludge. Sealing function Diesel engine lubricating oil must have a sealing effect on the engine to prevent the leakage of exhaust gas generated by the fuel in the engine’s combustion chamber and affect the normal operation of the engine.

Cooling The engine will generate a lot of heat during the working process, and the generated heat must be taken away in time to prevent the engine from overheating and affecting the normal operation, so the engine lubricating oil must have a cooling effect on the engine. Corrosion will occur to the parts of the engine, which requires that the engine lubricating oil must have an excellent anti-corrosion effect to prevent combustion products such as acid and water from corroding all parts of the engine. In addition to the above main functions, diesel engine lubricating oil also has the functions of auxiliary power transmission and vibration reduction. The main performance of diesel engine lubricating oil Diesel engine lubricating oil must prevent the corrosion and wear of engine parts, maintain the quality of each part, and ensure the smooth operation of the engine. At the same time, it must also meet the requirements of economical application. Therefore, diesel engine lubricating oil must have performance. Having a higher viscosity index Viscosity index is an expression method of the relationship between the viscosity of lubricating oil and temperature. The greater the viscosity index, the less the viscosity of lubricating oil is affected by temperature.
