Precision External & Internal Cylindrical Grinding

Tight-tolerance cylindrical grinding for shafts, journals, and precision diameters.

External and internal geometries with controlled concentricity and surface finish.

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

CNC Grinding Capability

HMPG incorporates CNC grinding capability within its cylindrical grinding operations to enhance repeatability and consistency, particularly for:

  • Production and batch work
  • Complex stepped geometries
  • Multiple-diameter components
  • Ongoing repeat orders

Large Capacity Cylindrical Grinding

HMPG offers substantial cylindrical grinding capacity:

  • Up to 590mm diameter
  • Up to 2.7 metres in length

Production & Batch Grinding

Our cylindrical grinding services support:

  • Production runs
  • Repeat batch work
  • One-off technical components
  • Finish grinding following machining
  • Complete manufacture of precision ground parts

Materials Processed

  • Carbon and alloy steels
  • Tool steels
  • Stainless steels
  • Hardened materials
  • Selected carbide components

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.
