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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

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

Six points of experience in precision metal parts processing

In the precision  machining of metal parts, hardware processing accounts for a large part. This time I will share with you what are the technological properties of hardware, I hope it will be helpful to everyone!

Casting performance: refers to some process properties of whether a metal or alloy is suitable for casting, including flow properties, ability to fill the mold; shrinkage, the ability to shrink the volume when the investment casting solidifies; segregation refers to the unevenness of chemical composition.

Welding performance: refers to the characteristics of metal materials that can meet the purpose of use by welding two or more metal materials together by heating or heating and pressure welding.



Top gas section performance: refers to the performance that laser cutting materials can bear upsetting without breaking.

Cold bending performance: refers to the performance of metal materials that can withstand bending without breaking at room temperature. The degree of bending is generally expressed by the ratio of the bending angle α (external angle) or the bending center diameter d to the material thickness a. The larger a or the smaller d/a, the better the cold bendability of the material.

Stamping performance: the ability of metal materials to withstand stamping deformation without breaking. Stamping at room temperature is called cold stamping. The inspection method is tested by cupping test.

Forging performance: the ability of metal materials to withstand plastic mold deformation without breaking during forging.

Processing is divided into the following four stages:

1.Face before hole

For parts such as box body, bracket and connecting rod, the plane should be processed first and then the hole should be processed. In this way, the holes can be positioned on the plane to ensure the accuracy of the plane and the position of the hole, and the processing of the holes on the plane is convenient.

2. Process the datum surface first

During the processing of the part, the surface as the positioning reference should be processed first in order to provide a precise reference for the subsequent processing as soon as possible. Called "benchmark first."

3. Finishing

The finishing cnc machining  china of the main surface (such as grinding, honing, fine grinding/rolling processing, etc.) should be carried out at the latter stage of the process route. The surface finish after processing is above Ra0.9um. A slight collision will damage the surface. In Japan , Germany and other countries, after the finishing process, they must be protected with flannel. Never touch the workpiece directly with your hands or other objects, so as to avoid the finishing surface from being damaged due to the transfer and installation between processes.

4, divide the processing stage

Surfaces with high processing quality requirements are divided into processing stages, which can generally be divided into three stages: rough processing, semi-finishing and finishing. The main purpose is to ensure the processing quality; facilitate the rational use of equipment; facilitate the arrangement of the heat treatment process; and facilitate the discovery of blank defects.
