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

Classification, main functions and performance of lubricating oil for heavy-duty vehicles

Classification, main functions and performance of lubricating oil for heavy-duty vehicles At present, lubricating oils for heavy-duty vehicles can be divided into diesel engine lubricating oil according to their purpose (heavy vehicles are mostly diesel engine vehicles, and only diesel engine lubricating oil is introduced here), gear oil and grease Three categories. The main function and performance of diesel engine lubricating oil. The main function of diesel engine lubricating oil, anti-friction effect Diesel engine lubricating oil must be able to reduce the friction of all parts of the engine, prevent excessive wear between the contact points of metal parts, and ensure the normal operation of the engine. Purifying and dispersing effect. Due to the high sulfur content and soot content of diesel fuel during combustion, there are more insoluble components in the engine oil. When the deposits formed by these substances block the engine piston ring, it will affect the normal operation of the engine, so the diesel engine The lubricating oil must have a good dispersing and cleaning effect to prevent the insoluble matter in the oil from forming attached sludge. Sealing function Diesel engine lubricating oil must have a sealing effect on the engine to prevent the leakage of exhaust gas generated by the fuel in the engine’s combustion chamber and affect the normal operation of the engine.

Cooling The engine will generate a lot of heat during the working process, and the generated heat must be taken away in time to prevent the engine from overheating and affecting the normal operation, so the engine lubricating oil must have a cooling effect on the engine. Corrosion will occur to the parts of the engine, which requires that the engine lubricating oil must have an excellent anti-corrosion effect to prevent combustion products such as acid and water from corroding all parts of the engine. In addition to the above main functions, diesel engine lubricating oil also has the functions of auxiliary power transmission and vibration reduction. The main performance of diesel engine lubricating oil Diesel engine lubricating oil must prevent the corrosion and wear of engine parts, maintain the quality of each part, and ensure the smooth operation of the engine. At the same time, it must also meet the requirements of economical application. Therefore, diesel engine lubricating oil must have performance. Having a higher viscosity index Viscosity index is an expression method of the relationship between the viscosity of lubricating oil and temperature. The greater the viscosity index, the less the viscosity of lubricating oil is affected by temperature.
