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

The expansion trend of precision computer numerical control machining

you High speed and high precision

Relating to accuracy cnc machining organization, high speed machining and accuracy are the everlasting goals of machine instrument development. With all the rapid progress science 

and technology, the renewal of mechanical and electrical items has more rapid, and the requirements for accuracy and surface area quality of parts control have become up and up.

2 Large reliability

The reliability of CNC equipment tools is actually a key indication of the item quality of CNC equipment tools. If the CNC equipment tool may play the high performance, finely-detailed and very efficient, and obtain great benefits, the 

important thing depends on it is reliability.

a few CNC lathe design CAD, structural style modularization

Accuracy CNC china  turning  business said that with all the popularization of computer applications and the advancement software technology, CAD technology has been thoroughly developed. CAD can 

not just replace the manual completing tedious pulling work, yet more importantly, it may carry out design and style plan assortment and stationary and powerful characteristics evaluation, calculation, conjecture and marketing design of 

considerable whole equipment, and can perform dynamic ruse and ruse of all operating parts of the entire machine.

four Functional amalgamated

The purpose of practical compounding is always to further enhance the production effectiveness of the equipment tool and minimize time used for non-processing assistance. Throughout the combination of features, the use selection of the 

machine device can be extended, the performance can be increased, and the multi purpose and multi-function of the model can be recognized. That is, a CNC lathe can understand both turning functions and milling digesting; or when it comes 


to milling. Milling can also be accomplished on the equipment tool.

five Intelligent, network, flexible and integrated

Based on the precision computer numerical control machining firm, the computer numerical control equipment from the 21st century would have been a certain smart system. The information 

of cleverness includes almost all aspects inside the numerical control system: to be able to pursue the intelligence of processing productivity and control quality, including adaptive power over the digesting process, course of action 

parameters will be automatically overal
