Femoral Head
The machining required for a femoral head involves
rough turning or rough grooving, semi-finish profile
turning, rough drilling, semi-finish milling, semi-finish
internal turning, internal grooving (undercut), cut-off,
rough turning, and semi-finish turning.

ISOTURN offered in all standard geometries, the
trigon (semi-triangular) turning inserts for axial and
face turning features six 80° corner cutting edges.
For profile machining, ISCAR provides intricate and
precise V-LOCK V-shaped special profile grooving
inserts for the range of 10-36 mm (.375-1.415 in).
Precision ground and utility CUT-GRIP full-radius
inserts are employed for the semi-finish turning stage.

SUMOCHAM integrates a clamping system that
enables improved productivity output rates, a shank
designed with twisted nozzles, and a durable and
stable body.

CHATTERFREE 4-flute endmills are utilized for
semi-finish milling; the endmills feature 38° helix and
variable pitch for chatter dampening with 3xD neck
relief. CHAMGROOVE internal grooving inserts are
applied for semi-finish grooving. The inserts possess
extremely small bore diameters starting at just 8 mm
(.315 in) (the other diameters are 11 mm (.433 in) and
15 mm (.591 in)) and incorporate internal coolant.

Semi-finish internal turning is done by ISOTURN
inserts with SWISSTURN toolholders and the
cut-off operation uses DO-GRIP twisted double-
sided parting inserts, which feature double-ended
twisted geometry for no depth of cut limitation.
For rough turning, the SWISSTURN ISO standard
insert range with small shank sizes is used.
Semi-finish turning is performed by CUT-GRIP
inserts. In addition to the large variety of general-use
precision ground and utility inserts in the CUT-GRIP
family, there is a vast range of inserts for specific
applications and materials.
