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

Good extreme pressure resistance

 

The performance of gear oils for heavy-duty vehicles. Good anti-corrosion and cleaning performance. Because the working environment of heavy-duty vehicles is generally poor, the dust and sewage in the environment are easily brought into the lubricating oil, and the temperature of the lubricating oil is high during the operation of the vehicle, which may cause complex problems. The chemical reaction produces acidic substances. In order to prevent the gear from being affected by the acidic substances in the oil and the sludge generated by the deposition of insoluble substances, the gear lubricant must have a good anti-corrosion and cleaning effect. Good extreme pressure resistance The extreme pressure performance of lubricants refers to the maximum load that the lubricant can withstand when it does not cause scratches or seizures during the pressure bearing process. Under normal operating conditions, the gear is in the state of elastic hydrodynamic lubrication of lubricating oil, but when the car is started under heavy load, climbing or encounters an impact load, a considerable part of the gear surface contact area will be in a state of boundary lubrication , The better the extreme pressure resistance of the lubricating oil, the higher the tooth surface load and impact load it can withstand. Good thermal oxidation stability The working temperature of the gear oil is high during the operation of heavy-duty vehicles. If the thermal oxidation stability of the gear oil is not good, the viscosity of the lubricating oil will increase, and the formation of sludge will affect the fluidity of the oil and produce acidity. Corrosive substances accelerate the corrosion of metals, and the polar deposits produced will also adsorb polar additives, causing the additives to precipitate out of the oil along with the deposits. These deposits will age and harden the rubber seals, and will also cover the surface of the parts. It affects heat dissipation, so gear oils for heavy-duty vehicles must have good thermal oxidation stability.

The main role of heavy-duty vehicle greases. Heavy-duty vehicle greases are mainly used to smoothly lubricate the chassis parts, universal joints and wheel bearings of vehicles, protect these parts from corrosion and wear, and at the same time, it can also play a role to a certain extent. The role of heat dissipation and vibration reduction. The performance of grease for heavy-duty vehicles The grease used for the chassis of heavy-duty vehicles requires good pressure resistance, water resistance and strong adhesion, while the grease used for hub bearings and other parts requires excellent mechanical properties. Stability, thermal oxidation stability, extreme pressure resistance and corrosion resistance.
