High Chromium cast iron is the third Generation white cast iron after common white cast iron and ni-hard cast iron. In Current times, high chromium cast iron has been the most suitable materials for abrasive resistant materials, and is widely used in mining industry, power industry, and other refractories. Typical component include mill rolls, industry pump(slurry pump, Mud pump) ect. Because high chromium cast iron workpiece belong to large scale castings, the blank will have some defects: Uneven margins,stomach,sand. So choose the right cutting tools will be very important.
Specific for all the defects and working problems, Halnn researched special cbn grades BN-K1, the characteristics are as follows:
1. Suited Materials: Chilled Cast Iron, Hi-Ni-Cr Cast Iron and High harness alloy cast iron
2. Suited Machining Type: Roughing
3. Typical Application: Alloy Cast Iron, Slurry Pump, Wear resistant castings
