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

Doppy oil and gas micro lubrication has obvious advantages

Oil-air lubrication is different from other traditional lubrication methods, and Doppel’s micro-air-air lubrication technology has obvious advantages.

Modular structure design, the number of lubrication points increases or decreases according to the actual situation.The amount of oil and gas can be supplied regularly and quantitatively, realizing on-demand supply and avoiding resource waste;

Oil-air lubrication can maintain the bearing position and friction position with continuous fresh lubricating oil input and reduce the temperature rise of the bearing. Tests have proved that at the same speed, the use of oil-air lubrication for spindle bearings of the same model and working conditions can reduce the temperature rise of the outer ring by 9℃~16℃ compared with oil mist lubrication. If the temperature rise of the bearing outer ring is kept the same, the oil-air lubrication is used Can increase bearing speed factor by more than 25%;

Oil-air lubrication has no or very little pollution to the environment.The compressed air is basically discharged through the bearing, which does not contain oil or contains very little oil, which is beneficial to the health of the operator;

Due to the continuous supply of fresh lubricating oil and the outflow of fresh air inside the bearing, it is difficult for foreign impurities to enter, and internal dirt is also easy to discharge, which can increase the service life of the bearing.

Oil-air lubrication is the continuous and accurate delivery of a small amount of lubricating oil to the electric spindle bearing, which has the advantages of energy saving and environmental protection, and extremely high reliability.

It can be seen that Peifeng Doppel Micro-Oil-air Lubrication not only has unique and professional technical advantages, but also conforms to the spirit of resource-saving, environment-friendly, reasonable lubrication, and high-efficiency that China is currently advocating, and has broad development prospects.
