- Recently, cemented carbide dies are used for many industrial products, due to their high stiffness and long life. Electric discharge machining is conventionally used and then, hand lapping is finally undergoes for mirror-like finishing of these products. In privious research, a simple lapping system for only plane surfaces of cemented carbide die was developed. In this study, several lapping tools for lapping of side, edge and corner were developed and evaluated by experiments. The system consists of a lapping tool, lapping vessel and conventional NC milling machine. The lapping vessel is placed on the table of the NC machine and the lapping tool is fitted with the spindle of the NC machine. Cemented carbide work piece is sunk and fitted in the lapping slurry and lapping processing is taken using the developed tools. Each lapping tool consists of a coil spring for supplying lapping pressure and the NC program was made possible to move the lapping head to contact and leave the work surface regularly for catching new grains and dressing. These lapping tools were finally evaluated by experiments. It is concluded from the results that the developed lapping tools were capable of lapping side, edge and corner of the cemented carbide work pieces for mirror-like surface finishing.
