New Geometry for Tough Rough Turning Applications

Walter has introduced double-sided ISO indexable inserts with RP7 geometry, providing increased process reliability in rough turning by combining a ground contact surface with an optimized profile that has a tailored protective chamfer to guard against fracturing. The RP7 benefits from a new design that features a specially designed T-land for protection against chipping, a ground seating surface, center curve design for extra cutting edge strength and a deeper chip groove that enables higher feedrates.

This geometry offers an alternative to the Walter MP5/RP5 geometry when a more robust cutting edge is required. It is designed for working on applications that include heavily interrupted cuts or forged parts with variable machining depths, and is also suitable for roughing steel materials.

In addition, the inserts' Tiger·tec Silver coating technology can extend tool life, thereby lowering new tool investment costs. "Costs are also reduced by having a two-sided insert, providing double the standard number of cutting edges on each indexable insert in comparison to the usual single sided insert typically used for heavily interrupted roughing cuts," said a company spokesperson. "These features, in conjunction with the new optimized geometry, make the new RP7 inserts a productive solution for rough turning applications."

The new RP7 geometry is available in the four basic shapes: CNMG, SNMG, TNMG and WNMG, and in grades WPP10S, WPP20S and WPP30S, and now in the extra tough grade WKP30S for applications requiring enhanced toughness.
