CoroCut® XS for external grooving applications
The CoroCut XS programme includes grooving inserts ranging in width from 0.5 mm, with
and without a chip forming geometry, and also dedicated parting inserts from 0.7 mm wide.
Turning, back turning and threading inserts can also be used in the same holder.
Guide-bush
Sub-spindle
If the machine has a sub-spindle a neutral style insert can be used without leaving a pip or •
burr on the finished component.
The subspindle can be used to pull away the component before the insert reaches the centre.
•
However, if the machine does not have a sub-spindle it is important to choose an insert •
with a right or left hand style insert with at least 10° front angle as this will enable the pip/
burr to be removed.
Practical hints
CoroCut XS holders with -X in the code are designed for parting operations in sliding •
head machines with a sub-spindle where there is a limited tool space. This tool enables
the sub-spindle to get close to the main spindle without colliding with the toolholder, see
illustration.
