Abstract

An attachment for fitting a tool to a hollow spindle of a machine tool, in a case where a shank portion of the tool has a taper-size smaller than that of a tapered hole of the spindle, comprises a hollow attachment body to be secured to the lower end of a ram of the machine tool, a sleeve rotatably supported in the attachment body, and an arbor assembly disposed axially movably in the sleeve. The arbor assembly comprises a stud arbor, a pull-stud to be engaged with a collet chuck disposed in the spindle, and a collet chuck to be engaged with a pull-stud of the tool inserted into a tapered hole of the sleeve.
