Rough turning High chromium cast iron Rolls/roller CBN inserts
1.Product Features
Solid CBN inserts is one of New grades researched by Halnn superhard,and it a new technology used for rough turning difficult to cut materials.Halnn superhard always devote to researching new materials to make the world no longer have difficult to cut materials.
2.Machining conditions
(1)Inserts Type:Machine folder indexable
(2)Processing:Roughing and Finishing
(3)Machining Hardness:Below HRC 35 for common cast iron and above HRC35 for high hardness cast iron
3.Advantages of rough turning high chrome alloy rolls
When machining cast iron and alloy parts,it has both well thermal shock-resistance and abrasion resistance.
4.Suited Materials
It mainly used for machining Cast iron and other hard to machining materials.
5.Application industry
Automobile parts,pump parts,motor cover,motor housing industry,such as automotive brakes,brake drums,pulleys and other components.Cast iron engine blocks,cast gearbox housing,cylinder liner,iron-based sintered metal.
