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

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

Analysis on the Technology of Distributed Motor Vehicle Safety Performance Inspection System

The distributed motor vehicle safety performance detection system technology is a server-workstation (Server-CI: ent) structure. The physical network topology is a hub-based (HUB) star structure, but the logical network topology is a bus type and the network transmission medium is non- Shielded twisted pair (UTP, unshieldedtwistedpair). Taking into account the rapid development of Internet technology and the need for remote data exchange in the future, the system provides a remote access router, which is convenient for users to query through the public telecommunication network by remote dialing at any place.

Detection process: Under the command of the LED dot matrix display and electronic voice system, the driver will drive the vehicle from the population into the detection line. First, record the basic data such as the license plate number, vehicle type and detection items on the registration machine, and the registration machine will The information is written into the database, and each station machine asks for the inspection items of the vehicle being inspected from the database. The driver passes through the detection of each station area in turn according to the prompts of each station machine display screen and electronic voice system, and each station machine will check The results are written into the database, and then the log-in management machine will collect and analyze the results, and automatically print out the inspection report. The average online time of each vehicle sent for inspection is 3 to 4 minutes, which allows four vehicles to be inspected online at the same time.
