Grinding at HPM

Overview

Grinding is the finishing operation that closes the gap between what turning and milling leave behind and what the drawing actually calls for on size and surface. It is offered at HPM as part of the same turn-key route, so a part can be turned, milled, ground and treated without leaving the supply chain.

Key Benefits

Tighter Size Than The Cutting Operation Leaves

Where a turned or milled surface will not hold the drawing tolerance, grinding takes the part the rest of the way.

Better Surface Where It Matters

Sealing faces, bearing diameters and mating surfaces get the finish the drawing specifies instead of the finish the roughing tool happened to leave.

Kept Inside The Same Supply Chain

Because grinding sits alongside turning, milling and treatment here, the part is not shipped out and back between operations.

Who It Is For

  • Buyers with sealing or bearing surfaces on the drawing
  • Companies whose current supplier subcontracts the finishing step
  • Engineers who need size and finish held together on the same feature

Problems It Solves

  • A machined surface that meets the profile but misses the finish callout.
  • Lead time lost shipping parts out to a separate grinding shop.
  • Size and surface controlled by two different suppliers.

Applications

  • Sealing faces
  • Bearing diameters
  • Mating and datum surfaces
  • Post heat treatment sizing

Grinding FAQ

Do You Quote Grinding From A Drawing

Yes. Send the drawing with the quantity and any treatment requirement and we come back with the price and the lead time. We do not machine to a standard house specification.

Can This Be Combined With Other Operations

Yes. HPM offers turn-key services, so this operation can be combined with turning, milling, wire cut, grinding, plating, anodizing, painting, hardening, carburization and nitriding inside one order.

What Is Checked Before The Parts Ship

Three things, all against your drawing: the material grade and chemical composition, every dimension against its tolerance, and the treatment against its standard.
