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.
