Surface grinding machine Osh-450 is intended for high-precision machining of flat surfaces of various parts, with help of wheel side and by end-face of grinding wheel, as well with use of devices for grinding wheel profiling and mounting of work pieces – profile surfaces, grooves, recesses.

Structural features:

  • High rigidity and vibration resistance of machine due to regular-style design of the bed, slide rest, column, table and grinding head guarantee stable precision and finish.
  • Even high-precision play-free positioning due to use of ball-screw bearings.
  • All work movements of the machines are automated.
  • Base parts made out of cast iron.
  • Working zone protection of cabinet type
