CUT-GRIP Grooving Inserts

March 01, 2011

ISCAR has launched a line of improved CUT-GRIP grooving inserts for ID grooving that features the N-type chipformer that has proven so effective in OD turning of problematic metals. Internal groovers with the advanced chipformer are available for diameters down to 22mm (.866").

In OD grooving applications, the N-type chipformer has outperformed competitors in numerous automotive parts in steels that consistently prove excellent performance compared to other chipbreakers: 42CrMo4, 20MnCr5 38MnVS6, 1045 and 4340. Several Tier-One suppliers report that it begins to reliably break up chips at feed rates as low as 0.002 ipr. By switching from a J-type to an N-type chipformer, one manufacturer of pinion gears in a 4340-like steel virtually doubled both hourly output and tool life, and completely eliminated a chip disposal problem.

The expanded CUT-GRIP line includes double-ended GINI inserts for ID turning and grooving and new sizes of GIMN 302 inserts in grade IC907.

    feed

    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • grooving

    grooving

    Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.

  • inner diameter ( ID)

    inner diameter ( ID)

    Dimension that defines the inside diameter of a cavity or hole. See OD, outer diameter.

  • outer diameter ( OD)

    outer diameter ( OD)

    Dimension that defines the exterior diameter of a cylindrical or round part. See ID, inner diameter.

  • turning

    turning

    Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
