COMBINED THREAD GRINDING MACHINES

RER Series

The main characteristics are:

  • Different combination of OD/ID grinding heads for multiple operations or rough/finishing under mass production requirement.
  • B axis for taper grinding.
  • External and Internal thread grinding and involute gear grinding with tooth head and base correction, fully CNC controlled
  • Direct drive technology
  • DOIMAK Easy Software will guide user step by step through data entering for each of the machining operations to be implemented.
