TOOL FOR CHIP REMOVING MACHINING

摘要

PURPOSE: A design of milling and drilling tools is provided which have interchangeable cutting edges and the tool tip has a wedging cooperation with the tool body such that the clamping force increases with increasing feed force. CONSTITUTION: A metal cutting tool includes a tool body rotatable about a center axis and a tool tip mounted on a front surface of said tool body for performing a cutting operation. A draw bar mounted axially in the tool body draws a rear surface of the tool tip toward the front surface of the tool body. Those front and rear surfaces include radial projections and radial recesses receiving the projections. The projections are wedgingly connected in the recesses to transmit all axial and rotational forces between the tool body and tool tip.
