Wear-Resistant Grade For Cast Iron Machining

ValEdge VPQ130 Silicon Nitride grade inserts from Valenite are offered in more than 80 styles with geometries suitable for milling, turning, boring and multifunctional configurations that can be used in either milling or turning applications. The grade's application range is expanded further with various shapes, thickness, relief angles and tolerance classes, plus dimple-style clamping, standard ANSI/ISO types and no-hole styles available for use with a variety of milling cutters, turning toolholders and boring bar designs. The grade features construction consisting of high-density Silicon Nitride and one that uses a low binder content resulting in tools that provide increased toughness and impact resistance for milling applications, as well as increased wear resistance at elevated speed ranges for more productive turning operations.

The grade's application range is expanded further with various shapes, thickness, relief angles and tolerance classes, plus dimple-style clamping, standard ANSI/ISO types and no-hole styles available for use with a variety of milling cutters, turning toolholders and boring bar designs.

The grade features construction consisting of high-density Silicon Nitride and one that uses a low binder content resulting in tools that provide increased toughness and impact resistance for milling applications, as well as increased wear resistance at elevated speed ranges for more productive turning operations. These tools also provide enhanced notch wear resistance that helps to improve tool life when applications involve "as cast" materials, the company says. Additional performance characteristics can be specified with various nose radii and land/hone designations.
