Abstract

A new machinability aid, which is a silica based composite oxide powder, has been developed for iron based sintered material. The machinability of sintered steels was much improved in high-speed turning by adding the developed machinability aid to the raw material iron based powder. The adhered layer, consisting of the same element as the developed machinability aid, was observed on the surface of the cutting tool by EDX analysis. It can be considered that some components in the developed machinability aid resided in the sintered body were softened and extracted from the work piece by friction heating during turning, and formed the layer that protects the tool surface. Moreover, the developed machinability aid promotes chipping resulting in reduction of the contacting area between tool and chip and suppression of tool wear.
