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
chip flow.
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
cutting forces.
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.
