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

Pay attention to antifreeze and tires in car maintenance in autumn and winter

It has become cold in a blink of an eye today. People are more likely to catch colds and get sick during the season. The same is true for cars. If you don’t take care of them well, you are also prone to problems of this or that kind. Do you know how to maintain your car during the season?
The face of a car, the face of a person, and the maintenance of a car is very important. However, during the interview, the reporter found that many car owners would hand over all their cars to the 4S shop for maintenance, and other drivers would only perform some simple inspections on the car. As for the temperature drop, what should the car do? Everyone can think of replacing the antifreeze, but it's just two words—I don't understand.
Antifreeze is a coolant with antifreeze function, which can prevent the coolant from freezing during winter parking, expanding the radiator and freezing the engine block. Wang Shiguo reminded that two colors of antifreeze cannot be mixed, let alone use water instead of antifreeze. Moreover, the service life of antifreeze is generally two years, and it must be replaced when it expires, otherwise it will cause corrosion to the vehicle’s engine and water tank. In addition, as the temperature drops, the rubber of the tires tends to become hard and brittle, and there may be air leaks or even tire punctures, so you should always check the tires of your car.
Antifreeze and tires are all ready, can you drive on the road, don't worry, don't forget to warm up the car before leaving the car.
At this time, the vehicle has not reached the optimal state, so the speed should be kept below 50 kilometers per hour. When the water temperature gauge reaches about 90 degrees normally and the engine speed is between 500 and 800 rpm, we can drive normally.
