ISCAR’s Innovative Clamping System
Rough turning is characterized by high D.O.C.
(4-10 mm) and high feed rates (0.4-1.0 mm/rev).
Usually large single-sided inserts are used on
top-clamp toolholders to withstand interrupted cut
and high machining load. The current method of
using single-sided inserts and top-clamp holders
has the disadvantages of a small amount of cutting
edges and interrupted chip flow due to
the obstruction of the top clamp.
ISCAR has developed an innovative dovetail pocket
combined with a lever clamping mechanism. The new
system provides a very firm and rigid insert clamping,
eliminating the need for a top clamp, which interrupts
The DOVE IQ TURN clamping mechanism can firmly
hold double-sided inserts featuring double negative
prism flanks. The dovetail pocket and insert prismatic
flanks prevent the insert from being lifted by the
Available are three insert geometries with prismatic
flanks: WOMG-R3P-IQ, COMG-R3P-IQ and
SOMG-R3P-IQ, designed with a new R3P
chipformer for rough turning of steel.
