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

Elimination of Gear Backlash in CNC Machining Feed System

Elimination of Gear Backlash in CNC Machining Feed System   The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on th

What is the difference between metal processing and sheet metal processing?


  • 1. Hardware actually refers to five metal materials: gold, silver, copper, iron, and tin. Hardware is the mother of industry and the foundation of national defense. From the perspective of the nature and use of hardware processing, it should be divided into eight categories: steel materials, non-ferrous metal materials, mechanical parts, transmission equipment, auxiliary supplies, work supplies, construction hardware, and household hardware. Each type of hardware has different uses and functions. , Can be selected according to specific needs.
  • 2. Sheet metal in sheet metal processing refers to the ability to perform data analysis and processing on even-thick plates. Sheet metal processing and hardware processing have important and substantial differences, mainly in production management processes such as shearing, folding, welding, and bonding. The natural resources of hardware include sheet metal and various sheet metal parts.

 What is sheet metal processing?

After understanding hardware processing, what is sheet metal processing? It refers to the key technology mastered by sheet metal technicians, and it is also an important process of sheet metal product forming. Sheet metal processing includes traditional cutting, blanking, bending and other methods and process parameters, including the structure and process parameters of various cold stamping dies, the working principles and operating methods of various equipment, and new stamping processes and new technologies. Parts metal plate processing is called sheet metal processing.

  • 1. Separate procedures are to separate the stamping parts and the blanks along a certain contour line during the stamping process. At the same time, the quality management of the separate sections of the stamping parts must be satisfied with certain requirements. These requirements analysis are all through the previous customers Selected by demand.
  • 2. Sheet metal processing is the same as hardware processing. In the forming process, the stamping blank is formed into the required product shape without damage, and meets the standard requirements.
