Parting and Grooving Insert features direct jet cooling.

Press Release Summary:

DO-GRIP parting insert is available with JET-CUT system, which features coolant hole that passes through insert to outlet near cutting edge. This applies coolant where it needs to go while simultaneously cooling insert internally. Designed for operations on stainless steel and high-temperature alloys, DGNC inserts come in .118 and .157 in. widths in C- and J-type chipformers and work with materials such as titanium, inconel, and austenitic stainless steel.

Original Press Release:

A New Parting Insert with Direct Jet Cooling

Iscar is introducing a new upgrade to the DO-GRIP parting insert. The new JET-CUT system features a coolant hole that passes through the insert to an outlet near the cutting edge. The new DGNC inserts are designed for parting and grooving operations on stainless steel and high temperature alloys. Often times 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.

The new JET-CUT inserts are also a great 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. The new DGNC inserts are a great solution as the coolant travels through the insert and exits a hole directly next to the cutting edge. This thereby applies 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.

Coolant can be supplied either directly to the DGFH-C blades used on regular blocks, or through the SGTBU-C blocks which have coolant passages or connecting ports. Inserts are available in widths of .118" and .157" in the C- and J-type chipformers.
