Abstract

A turret tool post includes a turning part having a plurality of turret surfaces on which tools for machining a workpiece are mounted, the turning part being configured to select any one of the tools for use in the machining of the workpiece by turning; a non-turning part on which a laser head of a laser machining device different from the tool is mounted, the non-turning part being arranged inside the turning part, an optical fiber cable being connected to the laser head; and a cut part (machinable part) that allows machining by the laser head to the workpiece under a state in which the laser head is selected.

First claim

What is claimed is:

1. A turret tool post comprising:
a turnable sleeve comprising an outer circumference wall having an outer circumference surface and an inner surface, wherein a plurality of first machining tools configured for machining a workpiece are mounted on the outer circumference surface, the turnable sleeve configured to turn for selecting any one of the first machining tools; and
a non turnable housing positioned inside the turnable sleeve within the inner surface of the turnable sleeve, the non-turnable housing being fixed in position and unturnable with respect to the turret tool post, wherein a machining body of a second machining tool extends in the non-turnable housing and is mounted to the non-turnable housing, the machining body configured to machine the workpiece, the second machining tool being a separate machining tool from the first machining tools,
wherein the turnable sleeve comprises an opening, the turnable sleeve configured to turn to a predetermined to position the opening relative to the machining body for the machining body to directly face the workpiece through the opening for the machining body to machine the workpiece.

2. The turret tool post according claim 1 , wherein
the turret tool post comprises an inner cover that is fixed to the non turnable housing and is configured to block the machining body of the second machining tool from the opening when one of the plurality of first machining tools is selected for machining the workpiece.

3. The turret tool post according to claim 2 , wherein
the turnable sleeve is provided with a cut part that communicates with the opening along a central axis of the turnable sleeve.

4. The turret tool post according to claim 1 , wherein
the non turnable housing includes a moving part that moves the machining body of the second machining tool through the opening toward the workpiece in a direction perpendicular to a central axis of the turnable sleeve.

5. The turret tool post according to claim 1 , wherein the machining body of the second machining tool includes a laser head configured to emit laser light to machine the workpiece.
