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.
