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

Summary table of dual trust and dual excellence in Nanjing automobile maintenance industry Peng Conference was held

 

On the afternoon of May 20th, Nanjing automobile maintenance industry double-trust double-excellence summary commendation and the third second member meeting of the association was held in Nanjing. More than 6 people attended the meeting, including leaders from relevant departments and associations of Jiangsu Province and Nanjing Municipal Government, representatives of automobile maintenance companies, and reporters from provincial and municipal news agencies. At the meeting, the leaders of the relevant departments of the province and the city gave the 6 Jiangsu provincial-level agency auto repair shops the title of civilized unit of the Provincial Department of Communications and the Nanjing Suxing auto repair shop received the title of "Double Trust and Double Excellence" advanced unit of the year. The company was commended and awarded medals.

The leaders of Jiangsu Transportation Management Bureau, Nanjing Transportation Bureau and Nanjing Automobile Maintenance Industry Association respectively summarized the development of the industry's “Double Trust and Double Excellence” activities and the deployment of the “Double Trust and Double Excellence” activities in the next two years. Delivered an important speech, and pointed out that the implementation of the “Traffic Safety and Transportation Market Management Year Activity Implementation Plan” formulated by the Municipal Transportation Bureau should be combined with the “Automotive Maintenance Market Management Year Activity Implementation Plan” formulated by the City Maintenance Office, and be combined with the Nanjing City's “Three Letters” The three excellent “comprehensive integration, and the in-depth development of the “double trust and double excellent” activities, it is necessary to organically combine the evaluation activities with the civilized unit creation activities of the Ministry of Communications and the Provincial Transportation The automobile maintenance industry is fully pushed into the 21st century.
