Abstract

Machining of sintered steel parts is sometimes necessary in order to produce complicated geometries like undercut which are hard to realize by uniaxial pressing and to meet customer requirements of higher dimensional accuracy. Although cutting costs account for a high percentage of the total manufacturing cost of sintered steel parts, and improvement of the machinability of sintered steel is desired. In this paper, performance characteristics of newly developed additive to improve the machinability of sintered steel were investigated on several conditions. The amounts of tool wear were significantly different according to the tool materials and cooling condition of cutting. However, in comparison with sintered steels without an additive and with the manganese sulfide, the machinability of sintered steel with new additive was improved simultaneously in drilling and turning for remarkable effects under various conditions.
