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

The use of trace oil and gas lubrication can increase the service life of the saw blade

Compared with the traditional cutting fluid lubrication method, the sawing oil-air lubrication device has great advantages:

● The sawing machine no longer needs to add filtering facilities, which saves the initial investment.

There is no need to process the materials after oil-air lubrication, and you can directly enter the following types of work.

● The oil consumption of oil-air lubrication is very low, and the cost of lubricating oil is greatly reduced.

It will make the processing process clean and environmentally friendly, which is more conducive to the maintenance of the machine tool.

The surface of the workpiece is dry and can prevent rust without subsequent cleaning.

To increase the life of the saw blade, it is necessary to choose a more suitable lubrication method. The oil-air lubrication device has an undoubted effect in improving the lubrication effect and life of the saw blade. According to statistics, the oil-air lubrication greatly reduces the frequency of saw blade replacement in the use of sawing. The use of sawing oil-air lubrication saves maintenance costs, and the benefits it brings are far superior to the use of emulsion lubrication and cooling. Therefore, the use of sawing oil-air lubrication is undoubtedly an economical and reliable lubrication solution.

The sawing oil-air lubrication device is a consumable oil-air lubrication. In the lubrication method, the oil-air injection method is used to automatically apply a small amount of fine oil mixed with oil and gas to the saw blade. Because the amount of lubricant is small and it is directly sprayed on the edge of the saw blade, It can well lubricate the saw blade and is an economical and reliable lubrication method. The supply of lubricating oil is also usually intermittently supplied by the saw blade during the cutting process. There are two ways to adjust the amount of oil. One is to adjust the oil supply frequency and the pneumatic pulse generator to adjust the time interval. The second is to adjust the amount of oil supplied by a miniature lubrication pump.
