Question

4. What would be the effect on the heat flux in the grinding zone of swapping from an aluminium oxide grinding wheel to a cubic boron nitride grinding wheel?

Answer 1

heal Clux Oi 18 amount of heat of Phergy per unit area. Grinding wheel A AIO, CBN goind the high temp near grinding zone. This q to as الربيا { renove O' = When goinding wheel of any metal Workpiece, the Workpiece noticiable amount of energy generate, Due to which temperature heat of energy rise the enter the wook Piece Can danage the Internal grains of workpiece. If it is porous metal (workpiece), the high temp lead to retempering or at higher teap, phase Change leading to ae hardening, be better if we heat this lan maxinun as possible possible from from the grinding Zone amount of heat go through Workpiece, high temp, surface Pristhe finish also damage. if tool has high high thermal Conductivity then heat generated In the goinding Zone be renoved through tool. K Alu,) thermal Conductivity, heat through itselt CBN Grinding wheel deject more due to high thermal conductivity. the grinding zone which go through the Workpiece. so that less the generated → Due to Can (KCBN? &o will decrease Heat Clux near
