R-Grind

Cylindrical grinder

R-Grind

  • The massive machine bed design with stable ribbing assures that even heavy components will have optimal results for surface roughness and dimensional accuracy
  • The hydrostatic spindle bearing and tailstock allow for extremely good isolation of machine vibrations and therefore provide excellent surface finish (R-Grind 20x)
  • Low maintenance due to automatic slide and headstock lubrication
  • 8-way graded belt drive in the headstock for broad range of speed control
  • Infinitely variable table feed by hydraulic drive with “soft-stop” at the end of traverse
  • Rapid traverse for the spindle
