Abstract
A machining apparatus capable of drilling a long workpiece from an end surface of a diameter-expanded part and drilling a short workpiece from an end surface of a stem part without inverting orientation of a collet and a sleeve in a chuck device is provided, as well as a method of using the same, and a chuck device for the machining apparatus. A deep hole drilling machine and a chuck device are included with a sleeve and a collet included inside the chuck device, and the collet and the sleeve each have both end openings opened toward the outside of the chuck device. The opening on one end side of each of the sleeve and the collet is directed to the deep hole drilling machine, and the collet is disposed on the other end side of the sleeve.
Claims11
A chuck device comprising:
- a tubular main body having one axial end surface defined as a facing end surface facing a drilling machine and the other axial end surface defined as an end surface facing a space in which the drilling machine does not exist;
- a sleeve disposed in the tubular main body with an axial direction aligned with the axial direction of the tubular main body;
- and
- a collet fitted in the sleeve with an axial direction aligned with the axial direction of the sleeve, the collet and the sleeve having both end openings opened toward the outside of both axial ends of the main body,
- wherein the opening on one end side of each of the sleeve and the collet is directed to an opening of the facing end surface,
- wherein the collet is disposed on the other end side of the sleeve such that no part of the collet is disposed on the one end side of the sleeve, and
- wherein a shaft-shaped workpiece can be inserted from either the opening on the one end side or the other end side of the tubular main body.
