PCBN Inserts for Cylinder Liner Machining

Cylinder liners are generally made of wear-resistant alloy cast iron containing phosphorus or boron, such as ductile iron, high-phosphorus cast iron and alloy cast iron. 

PCBN inserts is the most sutiable turning tools for the cylinder liner machining.

The cylinder liner is divided into dry and wet depending on whether it is in contact with the coolant. 

Which parts of the cylinder liner are processed by the cubic boron nitride insert?

CBN inserts turning repalce of grinding, and turning the upper and lower belts of the wet cylinder liner at high speed;

CBN inserts for high-speed turning cylinder liner excircle, water jacket wall, air tank, chamfering and flat section;

CBN inserts for finishing the excircle of the dry cylinder liner to reduce the machining allowance and machining process of the centerless grinding.

For example, our IB200 SNGA120412 brazed cbn insert for wet turning boron alloy cast iron cylinders, compared with coated carbide tools, the PCBN inserts for cylinder 

liner machining at cutting speed of 800m/min, the tool life improved 3 times, the cutting efficiency improved 1 time.
