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

Micro-lubrication technology is used for the bearing bush of the deweighting and balancing machine

Balancing machines are widely used in modern machinery, and the choice of lubrication methods is also very important. Traditional lubrication methods generally use oil lubrication, but in the deweighting process, the chips are easy to fall and get stuck on the bearing bush, which affects the deweighting balance. Accuracy.
If the bearing bush of the balancer adopts micro-lubrication, it can effectively solve the problem that the chips are easy to fall and get stuck on the bearing bush and affect the accuracy of the balance of weight removal. It will also obtain many benefits: The use of micro-lubrication can reduce oil consumption and save energy. Environmentally friendly
The running cost of the micro-lubrication system is very low. Compressed air is the power source of the system, and the energy consumption is low; it can reduce the damage caused by chip jamming between the bearing bush and the journal when using oil lubrication;
It can provide good lubrication to the drill bit and prolong the service life of the cutting tool-the drill bit.Compared with traditional lubrication methods, there are many advantages of micro-lubrication. In order to ensure the effect of micro-lubrication, special attention should be paid to the following two points:
Dry and stable air source: The stability of the air source pressure is an important factor for the normal operation of the micro-lubrication device.The power source of the micro-lubrication device is compressed air, so the stability of the compressed air pressure is very important.The moisture in the compressed air will directly affect the atomization effect, and the lubrication effect will also be affected. Therefore, the stability of the air source pressure and the drying of the air source are very important.
2. The design of the oil mist output channel size of the bearing bush of the balancer is very important, and its rationality directly affects the lubrication effect of the bearing bush.For the design of the bearing bush, in practical applications, the design passage of the bearing bush does not need to be too large, and the corresponding calculation can generally be carried out according to the size of the journal.The micro-lubrication itself has a very small diameter at the lubrication terminal.If the passage is too large, the air supply will be insufficient and the oil mist output will be too large, resulting in an impact on the operating environment.Full attention should be paid to the design.
