The issue was that there was no automated solution available on the market that allowed to deburr cross bores with a ratio of 1:1.

Application details

Application details

  • Bore diameter: Ø 8.0 mm intersecting with main bore Ø 8.5 mm
  • Material: 42CrMoA
  • Machining: horizontal
  • Volume: 1 Mio. bores per year

Proposed solution

Proposed solution

This application is predestined for HEULE's new X-BORES technology. The COFA-X tool has been designed for the deburring of cross bores with a bore diameter ratio of 1:1. The intersection of the bores will be deburred via the cross bore:

COFA C6X 8.0 S with blade C6X-M-0001-T

Machining parameters:

  • Cutting data:
    Speed: 500 rev/min.
    Feed: 0.1 mm/rev
  • Maschin: Shenyang CNC
  • Processing: horizontally
