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

Causes of confusion in our city’s auto parts market

 

At the same time, some business departments have become a place for thieves to sell dirty, making criminals even bolder and causing harm to public order. What makes people feel righteous is that this situation has become a strange phenomenon in the auto parts industry that the viewers are not surprised, the others are not afraid, and the recipients are worthy of it. It also severely threatened the status of state-owned channels. At present, our country is still in the primary stage of socialism, privately owned vehicles are less than 10 of the total number of vehicles, and most of the vehicles are public vehicles.

Whether it is buying auto parts or repairs, it is public money, and the purchaser does not need to pay for it. Therefore, buying accessories is not like buying department stores and daily necessities. If private individuals can benefit from it, why not do it. Moreover, most of the leaders of car users are not familiar with auto parts, let alone product quality. There are not many vehicles in some units, and these vehicles are in an important position for accomplishing the tasks of the unit and as a tool for leadership. So as long as the vehicle is running, the requirements for other issues are not strict. This is also one of the reasons for the existence of strange phenomena.

At present, there are too many auto parts outlets in Chongqing, which greatly exceed social needs. We should no longer blindly develop social outlets. At the same time, we must clean up existing outlets, resolutely ban illegal operators, rectify unqualified ones, and strengthen industry management. , Implement macro control, rational layout, and strengthen the management of purchases, finances, and prices. The main channel should provide assistance, support and guidance to social outlets in business.
