Abstract

PURPOSE: To make the cutting work more effective in using an automatic cramp type throw-away tool of round tip by such a construction that the turning operation of tip and the cramping operation when a tip has worn can conducted simultaneously.
CONSTITUTION: A L-shaped draw-in pin 2 is inserted in a hole provided at the center of a round tip 1, which is drawn toward the mounting seat 4 at the front end of the shank 3 by the action of the abovementioned pin 2 and cramped firmly. In the tip turning mechanism, a guide hole 15 is provided between the walls of a container room 14 of slider 9 and the mounting seat 4, and a push-out lever 16 and a push-out pin 17 are inserted in this hole 15. When the tip 1 has worn, the pressure system shall be switched over to another supply hole 33 to move the slider 9 back and let the rear end of the lever 5 fall along the slant 10. Thereby the cramp of tip 1 is released and the tip 1 is turned for a minute angle.
