Precision Internal Grinding & Honing

Bore grinding and honing for components requiring precise internal geometry, alignment, and surface finish.

Applied to bearing seats, housings, and critical bores.

Internal Diameter
(Bore) Grinding

Our internal grinding services are applied where bore accuracy and geometric stability are critical.

Applications include:

  • Bearing seats
  • Sleeves and bushings
  • Housings
  • Hardened internal diameters
  • Precision bores requiring tight tolerances
  • Components requiring strict internal-to-external concentricity
 

Internal grinding processes are structured to ensure:

  • Accurate bore size control
  • Roundness and concentricity integrity
  • Stable geometric alignment
  • Surface finish compliance

Precision Honing

Honing is performed where bore surface refinement and final geometry correction are required beyond conventional grinding results.

Honing supports:

  • Controlled surface texture development
  • Crosshatch pattern formation
  • Bore roundness improvement
  • Final dimensional adjustment
  • Surface finish optimisation

Internal Grinding &
Honing Capability

HMPG supports:

  • Production and repeat batch work
  • One-off technical components
  • Finish grinding following machining
  • Dimensional correction of worn bores
  • Restoration of internal diameters


All internal grinding and honing operations are verified using calibrated inspection and surface testing equipment.
