。[Claims for Utility Model Registration] (1) A hydrostatic bearing mechanism is provided on the axial extension of the rotating main shaft of the lathe to hold a part of the workpiece so as to be slidable and rotatable in the axial direction. A workpiece holding mechanism for a lathe, characterized in that the workpiece is held between an end reference surface on the spindle side and the hydrostatic bearing mechanism in a state where the workpiece is pressed against the end reference surface. (2) A utility model registration characterized in that the rotational force of the rotating main shaft is transmitted while an appropriate coupling mounted on the rotating main shaft and the workpiece are engaged with each other by fixing means such as a pin. Claim 1
The workpiece holding mechanism in the lathe described in Section 1. (3) The hydrostatic bearing mechanism is removably attached to a support member extending from a fixed part of the lathe in a state in which the hydrostatic bearing mechanism is coaxially aligned with the axis of the rotating main shaft. A workpiece holding mechanism in a lathe according to claim 1. (4) The hydrostatic bearing mechanism has a pressing means such as hydraulic pressure for pressing the workpiece against the end reference surface of the rotating main shaft, as set forth in claim 1 of the utility model registration claim. workpiece holding mechanism in a lathe.
