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

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

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

Causes of Chaos in Taiyuan Auto Parts Market

 

The current car ownership in Shanxi Province has reached 760,000, Taiyuan has 160,000, Taiyuan has 1,853 spare parts stores, and more than 90 repair shops have customer recognition and brand trust. The result is extremely low. Stable market share and weak market development capabilities force merchants to only make profit to ensure the market.

A single auto parts company cannot conduct scientific research on service standards. It is precisely because of the huge market capacity that cannot be scientifically and rationally deployed, the macro-scale advantage cannot be fully utilized, which eventually causes huge operating risks and economic losses. It can be seen that it is very necessary to introduce a kind that can make full use of the advantages of the same industry’s scale, and can ensure the intensive use of resources in management, and conduct a comprehensive clean-up of the local market. It is very necessary to rectify. In the past few years, the industry management in Taiyuan has regulated the auto parts market and developed the motorcycle parts market. However, from the perspective of the sellers, the general downturn in the auto parts market has caused fierce price wars and the high operating costs have made it unprofitable. They urgently need a new business model and lower-cost business premises.

And Blue Ocean Auto Parts World is just such an adaptive market. They understand that if they want to develop, they must unite, so that the tenants can get the fastest and the latest information transmission. Under the coordination and guidance of the administrative office, the Blue Ocean Auto Parts City is directly linked to the national auto parts manufacturers, and actively plays a role to seek greater development. . Industry management has a long way to go. As a form of “big market”, the auto parts block has emerged and has the conditions for large-scale operation. However, a considerable number of auto parts city operators do not have this kind of management quality, and think that adding the so-called “one-stop” service is quite good, and for the merchants, they simply move from here to there and change their business premises.
