Walter parting and grooving gradesClick image to enlarge

Walter has introduced three new Walter Cut GX Tiger·tec Silver CVD grooving and parting grades—the WKP13S, WKP23S and WKP33S—for use on steel and cast-iron applications.

These have been introduced in combination with Walter's proven geometries UD4, UA4, UF4, RD4 along with plunge grooving and parting geometries GD3 and CE4. This advanced grade and geometry combination is enhanced by the latest developments in a wear-resistant cutting material that boosts cutting parameters while maintaining or improving tool life.

The new, thicker Tiger·tec Silver CVD coating used with the WKP grades features aluminum oxide with optimized microstructure for maximum crater wear resistance and enhanced cutting speed due, in part, to reduced friction. A new silver flank face permits easy wear detection and full cutting-edge usage. In addition, a second-generation mechanical post-treatment creates compressive stresses that enhance toughness, reducing the chance of chipping on the cutting edge thereby boosting load capability and metal removal rates.

The WKP13S is for use under good machining conditions, primarily on steels such as high alloy, bearing and carbon steels as well as gray cast irons, ductile irons and compacted graphite cast irons. This grade delivers excellent wear resistance and cutting speed, especially in continuous cuts. WKP23S is a universal grade for a variety of applications, from continuous cutting on bar stock to machining interrupted cuts. It delivers superior wear resistance and cutting speed. WKP33S provides maximum toughness during unfavorable machining conditions.
