90° mounting •
It is very important that the insert is mounted at 90° to the centre line of the workpiece
in order to obtain perpendicular surfaces without scratch marks and to reduce the risk of
vibration.
Cutting fluid •
A large supply of cutting fluid, directed exactly on the cutting edge or under the edge,
should be used while the insert is engaged and throughout the operation.
Inserts mounted at 90° to the
centre line of work piece.
±0.1 mm Correct centre height settings •
It is essential when parting bars and
grooving relatively small diameters, that
the centre height setting is maintained to
a tolerance of ±0.1 mm. This has a major
influence on tool life, cutting forces and
pip size.
