As the product's aesthetic and functional requirements are getting higher and higher, the internal structure design of the product is becoming more and more complex, the shape design of the mold is becoming more and more complex, the proportion of free-form surfaces is increasing, and the corresponding mold structure is becoming more and more complex. These have put forward higher requirements on mold processing technology, and high-speed processing technology has been increasingly used in the processing and manufacturing of mold cavities.
Compared with traditional cutting, CNC high-speed cutting has greatly improved cutting speed and feed rate, and the cutting mechanism is also different. High-speed cutting has made a substantial leap in cutting. The metal removal rate per unit power has increased by 30%-40%, the cutting force has been reduced by 30%, the cutting life of the tool has been increased by 70%, and the cutting heat left in the workpiece is large. The amplitude is reduced, and the low-order cutting vibration almost disappears.
In the processing of high-hardened steel parts (HRC45~HRC65) of the mold, the use of high-speed cutting can replace part of the EDM electrical machining and grinding and polishing procedures, thereby avoiding the manufacture of electrodes and time-consuming electrical machining, and greatly reducing The amount of grinding and polishing of the fitter. For some thin-walled mold workpieces that are increasingly needed in the market, high-speed milling can also be successfully completed, and on the high-speed milling CNC machining center, the mold can be processed in multiple steps in one clamping.
