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

Environmental Analysis of Vehicle Electronic Control System


With the rapid development of electronic technology, especially the increasing maturity of automotive electronic technology, foreign lubricant supply vehicles are developing from mechanical to mechatronics. New lubricant supply vehicles on the market generally use computer control technology. In the past two years, computer control technology has been widely used in China’s new fueling truck projects, but the computer control of lubricating oil supply trucks is still a blank in China.

On-board electronic control system environment analysis When the lubricating oil supply vehicle is working, the electronic control system is in a very complex and harsh environment. For this reason, we first analyze the working environment of the lubricating oil supply vehicle.

The strong vibration environment of off-road operation. Vehicles, especially military vehicles, usually run on off-road roads. The electronic control system is in strong three-dimensional random vibration. Although the vehicle is generally in a stopped state when the electronic control system is working, the engine speed changes from low to low. High-speed changes, the electronic control system works in a variable frequency scanning vibration environment, and must undergo special anti-vibration treatment.

Main functions The new lubricating oil supply vehicle adopts electronic control technology, and its functions and various performance indicators have been greatly improved.

Fully automatic operation function for various tasks The main operation functions of the new lubricating oil supply truck have been expanded from 8 items to 13 items, all of which can be completed by the computer by clicking on the touch screen, such as left gun refueling, right gun refueling, double gun refueling, pipe refueling , Pipe-loaded oil, warehouse-loaded oil, mobile pumping station, circulating mixing, left gun withdrawing oil, right gun withdrawing oil, double gun withdrawing oil, pipe withdrawing oil, electric heating.
