S UMIBORON/Coated SUMIBORON G uidance for SUMIBORON Grades H Hardened Steel ● Advantages of Hardened Steel Cutting with SUMIBORON HARDENED STEEL MACHINING Below is an analysis on the use of CBN as compared to grinding: (1) In terms of cost investments, it is much lower in machine cost and overhead cost due to the fact that a CNC lathe is cheaper than a grinding machine. As for the quality of surface finish, inserts can machine different profiles with excellent surface finish, in a single set-up. Environmentally, sludge treatment for grinding is a hazard to the environment but the chips from the turning process can be collected and recycled.
