CBN Grades for Sintered Alloy and Cast Iron PMC7125 / BN7115 / BN7125

PMC7125 for Powdered Metal Machining

Ready to Create New Standards

S INTERED A LLOY

BN7115, BN7125, & PMC7125

 Features Improved wear resistance through high CBN content. Further, with improved CBN particle/binder boundary strength due to the special binder and improved binding strength between CBN particles thanks to our proprietary sintering process, excellent fracture resistance is achieved. Provides stable performance for high-speed machining of cast iron and sintered alloy.

Suppression of notch wear for excellent surface finish. Increased fracture resistance and improved dimensional accuracy General-purpose Coated Grade for Sintered Alloy Machining PMC7125

BN7125

BN7115

n Achieves high-efficiency machining of sintered alloy with a standard + 3 types of cutting edge variations Excellent thermal crack resistance in high-speed finishing of cast iron Also supports the machining of exotic alloys such as rolls, HSS, heat-resistant alloys, etc. General-purpose Grade for Cast Iron/Sintered Alloy Machining  Application Range for PMC7125 / BN7125 / BN7115

n Exhibits both excellent cutting edge sharpness and fracture resistance Stable edge sharpness suppresses burrs and tearing Grade for Finishing of Sintered Alloy
