A TOOL FOR CHIP REMOVING MACHINING AS WELL AS A SOLID INDEXABLE CUTTING INSERT

摘要

Tool for chip removing machining includes a basic body having an insert seat, and an indexable cutting insert fixed in the seat. The insert includes two cutting edges and at least two heads spaced-apart via an intermediate part and individually include a front portion having at least one cutting edge and a rear portion along which a pair of side contact surfaces are formed. The insert seat includes a front cavity including a pair of side support surfaces against which side contact surfaces of the cutting insert are pressed. The basic body is formed integrally of steel material and the seat is countersunk in the basic body so side support surfaces are integrated in the steel material. The cutting insert is formed integrally from a second, hard-wearing material having at least the same hardness as cemented carbide, the side contact surfaces of the insert being integrated in the second material.
