PG-9DOD: Compact OD Grinding Machine

The Glebar PG-9DOD is a compact OD grinding machine designed to handle small components requiring a tight concentricity such as rollers, pins, bushings, and other engine components. Designed to grind high­ performance engine components, it can be simply adapted to process equally challenging parts where the concentricity specification is critical. Parts can be staged on a precision arbor fixture ready to be loaded into the machine.

Key Features

  • Granite machine bed coupled with a high precision twin grip spindle holds extremely tight concentricity specs.
  • The servo driven arbor attachment provides part control during the plunge grinding operation.
  • Fully customizable and capable of processing high-volume components using a precision arbor as a fixture.
  • Outperforms conventional OD grinders by using the full face of the wheel to grind the part.
  • The wheel shape can be controlled finitely using a template tracing work wheel.
  • Remote connectivity simplifies troubleshooting and maintenance.
  • Adaptable to full automation for a complete turnkey solution.
