High-speed cutting technology for automotive stamping dies is of great benefit to save production time and improve production efficiency, but generally high-speed cutting requires milling speed greater than 40,000 revolutions per minute. All parts of the high speed lathe must be matched to make the machine work properly. What are the specific requirements for automobile stamping die production?

Because the high-speed cutting lathe is controlled by microcomputer program, it is necessary to have a central processing unit (CPU) and large-capacity storage equipment which can process large amounts of data quickly; have a faster data transmission capacity and network transmission capacity; have error compensation functions, including measurement error compensation, quadrant error compensation, thermal error compensation.

The drive system requires a large feed speed and acceleration, generally 20-30 meters per minute and 20-40 meters per second square.

Main shaft of high-speed airport. Because the stamping die in high-speed cutting to milling speed is very fast, so the speed of the spindle should also keep up with the general need to adjust between 10,000 to 100,000 per minute, with rapid speed-up and rapid precision stop performance. Therefore, the bearing structure of lathe generally adopts hydrostatic pressure, aerostatic and suspension magnetic levitation.

The machining of automobile stamping dies is carried out by milling cutters. Milling with tens of thousands of rotations tests the hardness and wear resistance of the cutters. Therefore, for cutting tool materials, cemented carbide and polycrystalline diamond must be used. At the same time, tool positioning must be precise and error controlled within 0.001mm.
