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

Braking after the car speeds up

  The friction coefficient of the sand-sticking roller is similar to the real road surface, which can simulate the actual braking situation of the car, increase the speed of the car and then brake, detect the braking force of the left and right wheels on the same car, and evaluate the car through calculation The braking performance of the car, the braking efficiency and stability data of the car during braking are given. The reaction roller brake test bench puts the front and rear wheels of the tested car on two rollers respectively. The two rollers rotate in the same direction under the drive of a motor and drive the wheels to rotate. At this time, the rolling of the wheels can be measured. resistance. When the brake air pressure of the tested car is greater than one atmosphere, the motor drives the wheels to rotate at the equivalent speed, and the tested car will brake. At this time, the wheel gives the roller a force that is opposite to the driving direction of the roller, that is, the braking force. This force causes the entire brake device to rotate with the roller as the axis and is balanced by the balance device to be relatively stationary. The balance is suspended on the base of the test bench and The change amount of the stretching sensor at the free end of the drum gearbox is reflected, and the change amount is converted into an analog electric signal and transmitted to the secondary instrument panel controlled by the single-chip microcomputer. After the conversion, the braking force value is displayed on the instrument panel panel. The working time of each braking is seconds. Once the wheels are completely locked, raise the brake pedal, otherwise the wheels of the car may be excessively worn. In the fully automatic automobile detection system, while the secondary instrument panel outputs the braking force value, the single-chip microcomputer transmits the digital signal generated by the converter to the main control computer system. The main control microcomputer substitutes it into the international market together with the pre-measured vehicle front and rear axle weight values.
