Solid CBN Machining Cylinder Liner

04 November 2022

The cylinder liner outer circle material is boron cast iron, hardness HB220~240, with the solid CBN SNMN120712 for long-range continuous finishing, cutting parameters: Vc=300~500m/min, ap=0.5mm, F=0.25~0.35mm/r.


The tool's durability is 6 times that of the original coated cemented carbide inserts, which solves the problem of frequent tool change because the tool is not durable and improves production efficiency.
