Quality & Inspection for Micro Machining

Micro machining requires disciplined process control and precise inspection to verify fine features, small diameters, and tight tolerances. B&H Machining holds tolerances as tight as ±0.0002” and supports features down to 0.050” diameter for precision assemblies.

We utilize a Keyence Vision System for fast, accurate, non-contact inspection of micro machined components. This system allows us to measure small dimensions, edge profiles, and critical features without contacting the part, helping maintain accuracy and part integrity.

  • Tolerances held to ±0.0002”
  • Feature verification down to 0.050” diameter
  • Non-contact optical inspection for delicate components
  • First article and in-process inspection support
