Working principle of slow wire processing

by
 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

by
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

Introduction of KOVAR parts

by
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR  machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stress,

Distributed motor vehicle safety performance detection system can be extended to make it have remote connection capability

cncmachining January 06, 2022

Features of electric vehicle safety automatic detection line:

  • (L) It integrates automobile inspection, vehicle management, and financial management.
  • (2) Parallel station setting is adopted to make the system operation more stable and reliable.
  • (3) Integrate the IC card into the system, that is, create an IC card intelligent recording system and an IC card instant query system. The former uses an IC card to replace manual login on the inspection line, which greatly improves the speed and accuracy of the inspection report. The latter only The IC card needs to be inserted into the reader, and the detection data of the car can be displayed quickly, which overcomes the shortcomings of manual query misoperation and slow query speed.
  • (4) It is equipped with advanced electronic voice technology to provide an automatic guidance system with both voice and text for on-site inspection, making the interaction ability stronger and more vivid

The distributed motor vehicle safety performance detection system can be expanded to enable it to have remote networking capabilities. For example, on the basis of the current network, only a multi-protocol router needs to be installed and through the dial-up telephone network, access to related data can be realized in a wide area, and information exchange and resource sharing can be achieved. The system has passed the acceptance of the Ministry of Public Security and the State Bureau of Technical Supervision, and is currently operating in good condition.

The automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry. Our automotive precision shop and experts deliver confidence. We have perfected the art of producing large component volumes with complete JIT reliability, backed by the quality and long-term reliability our customers expect.
