Exchangeable Heads
ISCAR’s families of rotating assembled tools with
exchangeable heads - MULTI-MASTER mills and
SUMOCHAM drills - enable substantial decreases in
downtime, a critical parameter particularly for small
volume and individual manufacturing.
Face contact between a head and a tool body
ensures that the head overhang is within strict
tolerance limits, resulting in high dimensional
repeatability of the assembly.

Turn Milling
Turn milling is a good option for machining heavy
rotary parts. In turning, the cutting speed is a function
of rotating velocity. If the main drive of a machine
tool does not allow rotation of large masses with the
required velocity, due to limitations of its working
characteristics, then the cutting speed is far from the
optimal range and turning performance will be low.
When turning large eccentric parts like crankshafts,
off-center masses of the parts cause unbalanced
forces that adversely affect performance. Turn milling
features low rotary velocity of a part, which prevents
this negative effect.

The majority of ISCAR’s indexable face milling cutters
are suitable for turn milling. The success of their
application depends on cutter positioning with respect
to the machined part, choosing optimal geometry of
inserts, and cutting data calculation.

Most of ISCAR’s indexable
face milling cutters can

be used for turn milling,

depending on the cutter

position in relation to the
machined part, optimal

insert geometry, and cutting

data calculations
