CNC Machining & Tooling

From milling small tight-tolerance aerospace components to instrument panels and control panels, GRP tubing high-speed machining delivers some apparent advantages. Our machines can machine most materials including steel, aluminium, composites and plastics like the military grade cast acrylic frequently used to manufacture illuminated instruments. Our CNC machinery and skilled engineers ensure that every job is produced to the exact standards demanded by today's market.

Every job is previewed on our CAD/CAM workstations and nested to reduce material wastage. Our rigorous quality control practices ensure every job is done to your exact specifications. As a fabricator, you will be ensured of consistent part quality and higher production rates.

Milling & Turning

Standard metal-working lathes and milling machines are sufficient for machining thermoset composites. High-speed steel tools can be used if their sharpness is maintained, but carbide or diamond-tipped tools will be more economical on large production runs.
  • Speeds, feeds and tools sharpened for brass machining are effective
  • Honed cutters will extend the service life
  • Cooling with water or air will increase cutting rates
  • Lathe tools should maintain a high clearance (between 10 and 20 degrees)
  • Setting the rake at zero or negative will improve performance.
  • Tool sets should be 1 to 2 degrees above center.
  • A surface speed of approximately 600 feet per minute is recommended.
