CNC Machining Processes

CNC Milling

3-axis, 4-axis, and 5-axis milling for complex prismatic parts. Ideal for enclosures, brackets, and structural components.

  • Multi-face machining in single setup
  • Complex contours and pockets
  • High-speed machining available

CNC Turning

Precision turning for cylindrical and rotational parts. Suitable for shafts, pins, bushings, and threaded components.

  • Live tooling for milling operations
  • Threading and knurling
  • Bar feeders for high volume

5-Axis CNC Machining

Simultaneous 5-axis machining for aerospace, medical, and automotive components requiring complex surfaces and tight tolerances.

  • Single setup for complex parts
  • Reduced cycle times
  • Superior surface finish

Mill-Turn Machining

Combined milling and turning operations for parts requiring both rotational and prismatic features in a single setup.

  • Complete parts in one operation
  • Improved accuracy
  • Reduced handling

CNC Tolerance and Inspection

Tolerance Capability

Standard tolerances follow ISO 2768-mK. Tight tolerances up to ±0.005mm achievable depending on part geometry, material, and feature size.

  • • Standard: ±0.1mm
  • • Fine: ±0.05mm
  • • Precision: ±0.02mm
  • • Ultra-precision: ±0.005mm (with conditions)

Inspection Methods

  • CMM (Coordinate Measuring Machine)
  • Optical comparators
  • Surface roughness testers
  • Hardness testing
  • Visual inspection
