Machining (CNC Milling)

Once the raw caliper body is formed, it undergoes precision machining on Computer Numerical Control (CNC) machines. This critical stage involves:

  • ✓ Rough Machining: Removing excess material to get closer to the final shape.
  • ✓ Fine Machining: Creating precise dimensions for piston bores, mounting points, fluid passages, and pad recesses.

Tolerances are extremely tight to ensure optimal performance and fit, particularly for complex units like the 581903KA01.
