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

EUPEC BSM50GD120DN2 is one kind of IGBT Module whose maximum continuous collector can reach 72A. In addition , BSM50GD120DN2 is the IGBT module with scre mounting and 17ECONOPACK 2A package.
 
IGBT module is with MOSFET structure. The IGBT gate is electrode electrically isolated by an oxide film. Since the Oxide film is thin, the common electric pressure should be range from 20 to 30V. We can draw a conclusion that the static electricity is the main cause of IGBT invalidation. The following are some attentions we need know in IGBT usage.
 
When using IGBT module, do not touch the terminal portion of driver. When necessary, discharge the static electricity of body or cloth by resistance and then touch.
 
When connecting the BSM50GD120DN2 driver terminal portion with conductive material, pay attention, not to have IGBT module connected before the wire is well connected.
 
When doing BSM50GD120DN2 module installation or change, you need attach special attention to the state of contact surface.
 
To reduce the thermal contact resistance,it is better to smear thermal grease between radiator and BSM50GD120DN2 IGBT module. Commonly there is cooling fan under the bottom of heat sink. The damage of cooling fan will cause IGBT module temperature increase. Therefore, regularly check the cooling fan. There will be a temperature sensor beside the IGBT module. When the temperature is too high, it will alarm and have IGBT module working stopped.
