Truing is the process of changing the shape of the grinding wheel as it becomes worn from an original shape, owing to the breaking away of the abrasive and bond. This is done to make the wheel true and concentric with the bore, or to change the ... SUPER FINISHING. Title:
High-speed grinding creates high temperatures in the grinding zone, causing the super abrasive particles to heat. Unlike diamond, however, CBN has a higher thermal resistance. In fact, at temperatures exceeding 800 degrees, CBN becomes harder than diamond and cBN is more than able to keep its cutting edge well up to 1000 degrees.
A wide composition-transition-zone was accordingly produced between the bond and wheel hub, and the binding strength was increased greatly. In the grinding process using the electroplated CBN wheels with heat-diffusion treatment, both the machining precision and surface roughness of hardened gear steel were improved effectively. 26. 2.1.3.
