1. Position the cutter
centrally over the drilled
hole with the cutter
rotating (v
c
75) and
move axially to flange
depth (Z = flange height
– chamfer size).
2. Feed cutter to engage
with radius compensa-
tion (Y = hole radius).
3. Interpolate 360° (fz 0.1
mm).
4. Feed back to hole
centre.
5. Retract cutter.

When machining aerospace engine components, one
tricky but often neglected operation is deburring holes.
By using a CoroMill 327 or CoroTurn XS back chamfering
tool it is possible to increase productivity while providing
a repeatable, mechanised, safe process – eliminating the
need for manual deburring and special tools.
The CoroTurn XS tool must be used with a Coromant
Capto adaptor to provide the correct clearance when used
in rotating applications.
