Component Applications

HMPG supports precision finishing and restoration of:

  • Shafts and journals
  • Spindle components
  • Bearing fits and housings
  • Precision bores
  • Tapers (HSK, BT, ISO)
  • Threads and profiles
  • Wear surfaces and chrome-restored components

Component Manufacture & Recovery

Where required, HMPG supports the manufacture and reconstruction of components prior to final grinding.

  • Manufacture from drawing or sample
  • Reverse engineering of worn or undocumented components
  • Reproduction of obsolete or unavailable parts
  • Pre-grind machining coordinated through trusted partners

This enables complete component supply from manufacture or recovery through to final precision grinding where dimensional accuracy, geometry, and surface integrity must be achieved.
