Abstract

The machinability of sintered compacts is generally regarded to be poor compared to wrought steels due to pores. The pores cause an interrupted cutting in a sintered body and a low thermal conductivity of a sintered compact. The machinability of iron-based sintered compacts with a newly developed machinability aid, JFM3, is investigated compared with that of sintered compacts with a manganese sulfide which is conventional machinability aid. The torque fluctuations in drilling sintered compacts with JFM3 were smaller than that with manganese sulfide. This improvement should be caused by inhibiting the interrupted cutting because of filling pores in the sintered compacts with JFM3.
