THE SELF-ROTATING INSERT
A
crucial component in the
SPINWORX
®
tooling system are
the self-rotating inserts, which have been optimally mat-
ched to the milling cutter seats of course. And it‘s the special
design features which make safe and long-term function pos-
sible here, too. There are cutting materials with and without
chip groove and different cutting edge geometries available.
Every single insert is delivered with an exactly matching pin.

inserts are always equipped
with a race. This protects from non-constant
rotation by forming built-up edges and supports
the characteristics of the embedded insert seat.
The race
Every insert is delivered with a perfectly mat-
ching pin. The cylindrical contact surface of the
insert has an exactly defined percentage contact
area. The cylindrical part of the pin, which provi-
des additional support in the seat of the tool, is
exactly matched to this.
The pin/insert combination
The inserts specifically developed for the
SPINWORX
®
system have a special cutting edge geometry.
The clearance angle W1 reinforces the cutting wedge while the clearance angle W2 provides suffi-
cient space for the cooling media. In addition, they stabilise the cutting edge and form the limiting
feature for the wear mark.
