Our precision machining facility provides the machining of complex components.

We have a 76,000 sq. ft extensive precision machining facility providing the machining of complex components including:

  • Landing Gears – pistons, axles, cylinders and torque links
  • Aero-Engines – impellers, casings, bearing housings and vortex reducers.
  • Airframes – nacelle structures and engine mount assemblies
  • ­Marine Power Applications

The facility’s process, assembly and test activities include frequency testing, hardness testing (Brinell and Rockwell), alochrom conversion, fluorescent penetrant detection and freeze assembly (bushes and tubes).

Accuracy is checked on large capacity coordinate measuring machines and as specialist suppliers of match-ground assemblies, we can manufacture to geometrical tolerances of less than 0.00001″.
