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

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

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

Basic safety requirements for mechanical equipment in cnc machining

The basic safety requirements of mechanical equipment in cnc machining are mainly that the layout of mechanical equipment is reasonable, which is convenient for operators to load and unload workpieces, observe processing, and remove debris. At the same time, Yaoyao is convenient for maintenance personnel to inspect and repair. The strength and rigidity of the parts and components of the mechanical equipment in cnc processing must meet the safety requirements, and the installation must be firm and not malfunction.

According to relevant safety requirements, the mechanical equipment in cnc machinined must be equipped with reasonable, reliable safety devices that do not affect the operation. E.g:

1. For the rotating parts and components in cnc processing, safety protection devices such as protective covers, protective baffles, and protective railings should be installed to avoid the occurrence of twisting.

2. For parts and components that can cause dangerous accidents such as overpressure, overload, overtemperature, overtime and overtravel in cnc processing, safety devices should be installed. Whenever a dangerous situation occurs, the safety device acts to eliminate the danger and prevent it. The accident happened.

3. When some actions in cnc processing need to warn or remind people, signal devices or warning signs should be installed.

4. For some parts and components that cannot be reversed in the cnc processing, interlocking devices should be installed. That is, a certain action must be performed after the previous action is completed, otherwise it will not be possible to perform the action. This will ensure that accidents will not occur due to the wrong sequence of actions.
