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

Minute lubrication processing crankshaft oil hole

<strong>Minimum lubrication technology is</strong> a new lubrication technology that makes the machining process more effective, energy-saving and cleaner. It can greatly improve production efficiency and increase the life of cutting tools by 50% during the machining of crankshaft oil holes. Above and get a clean workshop environment. <strong>Minimum Lubrication</strong> technology is a lubrication method that uses compressed air as power to atomize trace lubricating oil into micron-level suspended oil particles and transport the suspended oil particles to the cutting area. It is completely different from the traditional spray lubrication method that uses a large amount of cutting fluid or cutting oil: only spray lubrication cooling is provided during the cutting process, then there is less lubricating oil left on the chips and the workpiece, and the residual lubrication of the spray method Compared to oil, it is very small. Production plants use <strong>micro lubrication technology</strong> to process crankshaft oil holes, which can achieve higher production efficiency and lead the development of micro lubrication technology to adapt to changes in market demand. <br /> <strong>Minimum lubrication</strong> technology can bring good economic and environmental benefits, because in crankshaft oil hole processing, only a small amount of lubricating oil is needed to achieve good lubrication effect. So that the factory can obtain considerable economic benefits after using the <strong>micro lubrication</strong> technology. The crankshaft machining center effectively transports the oil mist to the cutting area through the main shaft and the internal cold drill. The control system of the machine tool is connected with the <strong>minimal lubrication</strong> device, and the opening frequency of the ball valve and the inner hole of the drill are changed according to the requirements of the processing technology. The size of the channel automatically adjusts the delivery volume of the lubricating oil mist. <br /> &nbsp;&nbsp; <strong>Minimum lubrication</strong> technology applied to crankshaft oil hole processing has advantages as follows: <br /> (1) Oil mist can penetrate into the friction point to achieve a good lubrication effect ;<br /> (2) In deep hole machining, the compressed air flow rate can take away the cutting heat, and a large amount of cutting heat is taken away with the chips. <br /> (3) The fuel consumption is low, and the cutting friction points always maintain proper and reliable lubrication; <br /> (4) The product is small in size, the air source is low, and the operation is simple; <br /> (5) Reduce the machine tool Maintenance costs and operating costs. <br />
