Hardened steel processing and the development of CBN tools

From the perspective of turning hardened steel, hardened steel machining tool selection has several aspects: First, the tool material selection: general hardness from the processing point of view, the cutting hardness less than HRC50 small depth of cut and feed a small case the hardened steel workpiece, Abrasive grinding is a better choice. CBN tools suitable for workpiece hardness higher than HRC50 situation, try to avoid synthetic diamond powder tool in the semi-finishing and roughing, and the overall CBN inserts can be suitable for interrupted cutting, heavy roughing. Second, CBN tools manufacturers / grade selection and edge treatment, a good roughing CBN tools not only chipping, and can finish at high efficiency while maintaining long life and good surface finish.
In the process of abrasive grinding steel, commonly used CBN welding tools, welding tools CBN currently doing a lot of manufacturers, mostly with CBN composite sheet by cutting, welding CBN tools made ​​of a variety of complex grade characteristics CBN tools confused and are not very clear, which is CBN welding tool market in an embarrassing situation.
