SPECIFICATIONS
Work spindle rotating and table reciprocating are ganged/linked to achieve spiral movement.Work table travels along V-and-flat guide ay (i.e. one guide way is V-located on the opposite end of wheelstock rotary drum).The internal grinding wheel spindle adopts a high-speed (E-spindle) grinding wheel dressing by a diamond disc.
CNC system is SIEMENS 828D
These axes are all driven by SIEMENS servo motors Bearings of table ball screw and wheelstock feedings ball screw are from world-famous brands.
