ISCAR’s Tang-F-Grip, a four-insert blade,
is capable of delivering faster parting and
superior quality
ISCAR’s Tang-F-Grip is described as a
revolutionary parting system designed for
increased productivity, offering a unique
parting concept for bar up to 120 mm bar
diameter.
Tang-F-Grip is said to be simple to mount
and operate on all machine types, including
multi-tasking units and machining centres on
the X-axis, without any need for special
adjustment. In fact, the system enables the
mounting of both Tang-F-Grip and Do-Grip
blades on the same blocks, ISCAR (https://
is.gd/tuhuno) points out.
Its square blades possess a support
system that provides totally
vibration-free grooving and
parting. Tang-F-Grip also
saves on set-up time
as, in cases of pocket
damage, the block’s
design allows a blade to be
rotated to a new pocket
without set-up.
Tang-F-Grip is intended for high
feed parting. It extends insert life,
TOOLING DON’T MAKE PARTING MORE DIFFICULT THAN IS NECESSARY
improves surface nish and part
straightness, and features high stability –
especially when parting large diameters. The
new patented blades reduce cutting time
and also enable signi cant material savings
– for instance, a 120 mm bar can be cut
with a 3 mm blade with HF (high feed)
inserts at a feed rate of up to 0.4 mm/rev.
The HF tangential single-ended insert
employs a unique chipformer technology
that allows unobstructed chip ow, which
increases insert and blade tool life, and
leads to very high productivity gains.
But all Tang-Grip inserts can be
integrated into the Tang-F-Grip system, which
is also compatible with Do-Grip DGN
double-sided twisted
geometry parting
inserts, to provide an
extensive choice of
parting widths for all
application ranges. ISCAR offers a wide
variety of chipformers and grades to ensure
high performance and extended tool life.
A revolutionary and secure clamping
method using a tangentially-orientated
pocket facilitates pocket life that is three
times longer than that of any other
conventional self-grip system, the company
further claims. The system’s robust
clamping method enables machining at high
feed rates and provides excellent
straightness and surface nish
characteristics, while the at top
con guration prevents chip obstructions
under all possible machining conditions.
The employed Jetcut system incorporates
through-coolant channels to deliver coolant
close to the cutting edge, which improves
chip formation and slashes ank and
cratering rates. The targeting of high
pressure coolant directly to the cutting zone
on materials such as stainless steel or high
temperature alloys mitigates effects of high
temperature near the cutting edge, as well
as material adhesion.
