Solid PCBN Inserts for Cast Steel Roll Roughing Processing
Name: PCBN insert
Model number:RNGN1204
Workpiece:Cast Steel Roll
Usage:High nickel chromlum cast steel roll eoxdernal circle fturning
PCBN inserts are designed to deliver maximum productivity in specific applications. PCBN inserts compacts has excellent wear resistance, impact toughness, high chemical stability and heat stability, excel on cast irons, hardened steel, powder metal, hard facing alloys, HSS, and high temperature alloy. They are commonly used in the automotive, aerospace, heavy machining, die and mold, roll industry and medical industries
Feature
*Suit for roughing and low speed machining with heavy load.
*High thermal conductivity and definite impact resistance.
*Suit for rough machining of high-hardness alloy cast iron, gray cast iron, nodular cast iron and other materials.
*Longer cutting tool life and better chipping
