Face grooving
For components having an axial groove into the component it is
important to choose the correct toolholder. The toolholder must be
adapted to the bending radius of the groove and should therefore be
curved. See Face grooving shank holders on page 61.
CoroCut 1- and 2-edged grooving and turning inserts with GM, TF
and RM geometries can be used. For small first cut diameters
Q-Cut 151.3 with geometry 7G and 7P can be used. Normal feed
methods should be used. SeeTurning of grooves on page 30.
The CoroCut MB and CoroTurn XS system are dedicated for a
smaller diameter range and is available with face grooving inserts in
widths from 1.0–3.0 mm.
Toolholders
Use CoroCut solid toolholders especially designed for face grooving type RF/LF (0° insert
angle) or RG/LG (90° insert angle) covering first cut from 34–400 mm diameter giving the
best stability.
For grooving depths up to 4.5 mm, a special shallow grooving toolholder is available, see
page 62.
CoroCut SL face grooving blades can also be used together with Coromant Capto and shank
tool adaptors, making it possible to build many different combinations.
