External Cylindrical Grinding

Our external cylindrical grinding services support:

  • Shafts and journals
  • Hardened and heat-treated components
  • Stepped diameters and precision fits
  • Production and repeat batch components


Grinding processes are structured to ensure:

  • Accurate diameter control
  • Roundness and concentricity integrity
  • Stable and repeatable outcomes
  • Controlled surface finish achievement

Internal Cylindrical Grinding

Internal cylindrical grinding is performed where bore accuracy and geometric alignment are critical.

Applications include:

  • Precision bores
  • Sleeves and bushings
  • Housings
  • Components requiring tight internal-to-external concentricity

Surface Finish &
Geometric Accuracy

Cylindrical grinding is frequently the final operation determining fit and performance.

HMPG focuses on:

  • Tight diameter tolerances
  • Concentricity and roundness
  • Achievement of specified surface finishes
  • Inspection using calibrated surface testing and measurement equipment

 

Each component is verified against specification prior to completion.
