Valve Seat-Ring grinding machines are suitable for 4” - 70” inches seat dimensions. Grinding is performed with cup wheel tools.

Spindle motor power range goes from 5.5 – 7.5 kW and rotation speed from 0 – 10000 rpm. RGM range  machines have three axes, all of which are servo driven. Extra equipment includes refrigeration unit for spindle and coolant, automatic tool changer and a complete liquid filtering system.

  • RGM machines have been designed to high quality grinding requirements – including coated rings. Spindle positioning axes are equipped with accurate electronic linear scales. High quality finished parts can be achieved due to the minimized run-out of the clamping chuck.
  • Coolant for the tool through the spindle.
  • Machine bed is designed so that the dust and grinding waste is flushed away from the machine. Then, grinding waste is separated by filtering.
  • Ring may be clamped by manual or hydraulic chuck.
  • Friendly HMI makes the use of the machines easy.
