Now the tungsten steel milling cutter cutting liquid cooling, air cooling, oil mist cooling, much of their influence on the coating such as carbonization tungsten steel milling cutter, aluminum coating black for cutting coolant, now much gas cooling of the tool life and processing effect, the titanium coated bronze selenium suitable for gas cooling, now with cutting fluid cooling, service life of the tool (and probably do under normal use contrast) much impact and processing effect (the key to solve the problem)
There are many kinds, we have a client of our own developed a device called atomization, can improve carbide tool life of more than 20%
The use of spray cooling, can greatly improve the tool life and surface roughness of the workpiece, Shenzhen sea will have to sell.
1. the selection of cutting parameters and the selection of cutting speed mainly depend on the material of the workpiece being processed. The choice of feed speed mainly depends on the material of the workpiece being machined and the diameter of the end mill.Tool samples of some foreign manufacturers of cutting tools have the selection table of cutting parameters, which can be referred to. But the selection of cutting parameters is also affected by the machine tool, cutting tool system and machined workpieceThe cutting speed and feed speed should be adjusted according to the actual situation, because of the influence of the shape and the clamping mode. When the tool life is taken as a priority, it is appropriateReduce the cutting speed and feed speed; when the cutting edge is not in good condition, it can increase the cutting speed.2. cutting method is adopted in milling, which is helpful to prevent blade damage and improve tool life. But there are two points need to pay attention to: (1) if the general machine tool processing, should try to eliminate the feedGap of the mechanism; when the surface of the workpiece is left with oxide film or other hardened layer formed by casting and forging process, reverse milling should be adopted.3. the use of carbide end mills, high-speed steel end mills use and use of relatively wide range of requirements, even if the choice of cutting conditions slightly inappropriate, but also does not appear too big problem. andAlthough the carbide end mill has good wear resistance in high-speed cutting, its range of application is not as high as that of high speed steel end mills, and the cutting conditions must be in strict accordance with the toolUse requirements.
