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

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 deep hole

Deep hole machining is the machining of holes with a ratio of hole depth to diameter greater than 10. In the machining industry, more holes are processed, but it is difficult to guarantee the tool life and the quality of the processed parts in the processing of deep holes. Solving the problems encountered in deep hole machining in machining and improving processing efficiency are the main research directions of deep hole machining. On the one hand, deep hole machining needs to choose suitable cutting tools to improve processing parameters. On the other hand, it is also necessary to choose a suitable and ideal lubrication system, because choosing a suitable and ideal lubrication method can improve the life of cutting tools and the quality of processed parts. . At the same time, it can also reduce the pollution of oil pollution to the environment and the harm to the human body. <br /> In deep hole drilling, traditional lubrication technology uses a large amount of cutting fluid pouring to achieve lubrication and cooling. Although this traditional lubrication method can also play a role in lubrication and cooling, it needs to consume a large amount of cutting fluid. In addition, the cutting fluid will be sprayed on the equipment and work site, which will have an adverse impact on the environment and the human body. In addition, the recovery and treatment cost of the waste fluid is also very high. The use of Doppeld deep hole drilling micro-lubrication system can easily solve the above problems, and at the same time, the processing quality and processing efficiency will be greatly improved, and the service life of the drill will be prolonged. The data shows that the operating cost of the system is reduced by more than 50%. <br /> The Doppeld deep hole drilling micro-lubrication system is mostly used in the processing of auto parts: crankshaft oil hole processing, engine box, etc. There are more deep holes in these processing, and the number of holes is relatively concentrated. To make the micro-lubrication play a better role, it is necessary to choose a drill bit with an internal cooling channel when selecting a drill bit, so that the micron-level oil mist can smoothly reach the cutting area. In addition, when choosing a lubricant, it is necessary to choose an environmentally friendly lubricant and fully consider the viscosity of the lubricant. Because the viscosity of the oil directly determines the atomization effect and the size of the oil mist particles after atomization. The pressure of a suitable gas source is also very important, because the size of the gas source pressure is an important factor that affects the formation of oil mist. In specific applications, if you use coated alloy drills to obtain higher processing efficiency, micro-lubrication can also play a better role. <br />
