Iscar Metals Inc.’s (Arlington, TX) is introducing a new upgrade to the DO-GRIP parting insert. DGNC inserts are designed for parting and grooving operations on stainless steel and high temperature alloys. Oftentimes when machining these materials, the temperature near the cutting edge becomes very high, thus causing premature wear. By applying coolant to the cutting zone this can be reduced. These inserts provide a solution to grooving and parting applications where there is a problem getting coolant to the cutting edge. Sometimes in these applications, the way the chip exits the workpiece prevents the coolant from reaching the cutting edge when traditional coolant delivery methods are applied. With these inserts, the coolant travels through the insert and exits a hole directly next to the cutting edge—applying coolant exactly where it needs to go while also internally cooling the insert at the same time. The application of coolant through this system has shown to increase tool life and provide a smoother surface finish. In addition, materials such as titanium, inconel and austenitic stainless steel tend to strain harden during the cutting process and thereby produce long and tangled chips. By efficiently applying cooling through the JET-CUT system, flank and cratering rates are reduced thus substantially increasing tool life. Inserts are available in widths of .118” and .157” in the C- and J-type chipformers.
