Coolant Solver
In machining exotic superalloys, effective coolant
supply is a cornerstone of success. Pinpointed high-
pressure cooling (HPC) can be a significant tool
to improve cutting performance. It is a real source
for greater tool life, better chip control, and higher
productivity.

One of the latest ISCAR's developments is a family of
turning tools with ISO-type indexable inserts. The tool
design utilizes an upper clamp for reliable securing of
the inserts even during heavy and interrupted cuts.
The previous turning tools with the HPC option had
a lever clamping mechanism as an upper clamp
would obstruct a jet of coolant from reaching the
cutting edge.

The newly developed tools integrate a hollow upper
clamp that allows for solving two problems:
• strong and rigid insert clamping
• eliminating any obstacle for the coolant jet
on its way to the cutting edge
Hence, the clamp, which serves in the new tools as
a coolant nozzle, received an additional important
functional feature.

The new products with through-tool coolant supply
are beneficial not only in machining with HPC. Their
applying to turning with conventional external "low"
pressure cooling (10-15 bars) also provides better
performance.

In parting and grooving, especially in deep grooving,
efficient chip forming has crucial significance.
Pinpointed high-pressure cooling of a cutting edge
significantly diminishes chip jamming and reduces
built-up edge. Within the past year, ISCAR expanded
the range of its HPC products by introducing new
face grooving tools with HPC option. These tools are
suitable for coolant pressure of up to 140 bars.
