Heller RSA surface grinder

The horizontal-spindle surface grinder, also called a flat grinder or surface grinding machine, leaves flat faces with very precise flatness and finish. It is the standard machine for moulds, dies, plates and tooling.

Surface grinder models

  • RSA 450: 450 x 150 mm table, magnetic chuck and Fagor digital readout (DRO).
  • RSA510 SZ, RSA600 SZ and RSA800SZ: automatic Z axis, ball screw on the Y axis and fine-pole electromagnetic chuck.
  • RSA510, RSA600, RSA800, RSA1000 and RSA1500 NC2: automatic Y and Z axes with servo motors and PLC, Siemens touchscreen and tables up to 1500 x 600 mm.

All include coolant equipment, diamond dresser holder, grinding wheel balancer and CE certificate. The SZ and NC2 models add a magnetic swarf separator and full table guarding.
