Abstract

PURPOSE:To prevent the change of a position of the edge, and to improve the accuracy of machining by a method wherein only a keyway is grooved onto the circumference of a tool, tapered contact between a main shaft and the tool is made constant at all times, and positive drive by a key and the keyway is attained. CONSTITUTION:The tools are exchanged by means of the only keyway 18 grooved to the tools T and a movable key 65, which is connected to the way 18 and formed in a shape that is movable fore and aft to the main shaft 11, during the revolution of the main shaft 11. A connecting head section narrower than the width of the way 18 is formed to the key 65 in a projecting shape. A draw rod 22, a spring 23 and a cylinder 24 projecting to a rear end section of the main shaft 11 from a device which clamps or un-clamps the tools T to the main shaft 11. A drive motor 31 responds to tool exchanging instructions, and can turn and control the main shaft 11 at predetermined low speed, thereby the key can be connected. According to this constitution, the change of the position of the edge is prevented, and the accuracy of machining can be improved.
