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,

The development status of domestic electronic products

cncmachining December 08, 2021

Several companies are convinced that the Detroit auto plant will start selling models equipped with real-time traffic reporting devices at the end of 2001. General Motors and other automakers said that problems with the provision of traffic information have forced them to postpone the launch of the product. The era of calculating the distance in the car has arrived. Alerts and location information will be automatically sent to.

But it is certain that the realization of all this will not be a distant dream. actually. Technologies related to this project have been partially integrated into the automotive industry, such as navigation systems and collision avoidance systems. Looking at the major achievements in automotive technology in recent decades, almost without exception are the results of the application of electronic technology, and since the 1980s. Great progress in the automotive industry. It is also realized by electronic technology (especially computer and integrated circuit technology). The use of electronic technology is the best solution to many technical problems faced by automobiles.

Therefore, the level of a country’s electronics industry and its application in the automotive industry determine whether it can take the initiative in the future competition in the world automotive industry. China will accelerate the development of intelligent transportation technology. At present, most of the application of electronic technology in domestic automobiles is still in its infancy. There are only a few manufacturers. The electronic devices that are mainly used in some Sino-foreign joint venture cars mainly include engine fuel injection, electronic ignition control, airbags, ABS and other fields in terms of automobile safety. And most of them are assembled directly from foreign products.

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.
