Design of High Speed NC Crankshaft Grinding Machine

摘要

Siemens AG SINUMERIK820 is used for high-speed numerical control (NC) grinder, which integers CNC and PLC and is safe and reliable. The mechanism of high speed spindle is that the motor and spindle are combined as one body; rapid feedrate is realized by steep-lead ball screw and increasing feed servo motor rotation speed; the wear particles of wheel are mainly of cubic Boron Nitride and diamonds; and the machine is more stable and reliable.
