a Hardened Steel Bearing Steel Coated SUMIBORON BNC160 High precision machining with surface finishes down to 1,6 Rz possible thanks to smooth coating I General Use the copper coloured Sumiboron grade BNC160 to improve surface integrity as well as machining accuracy. The TiCN based smooth surface ceramic coating and the newly developed Sumiboron substrate enhances edge strength and wear resistance making high precision machining with surface finishes as low as 1,6Rz readily achievable. This new grade is ideal for turning components that previously relied on precision grinding machines for final machining. Advantages Excellent surface roughness A consistent surface roughness is maintained for hours because wear at the boundary is so gradual. High Precision Machining High precision work previously ground, can now be turned. Enlarged scope of application A wider range of hardened steels can be cut using Sumiboron the result being high productivity on close tolerance machining applications.
