Abstract

A machine tool includes a spindle equipped with a workpiece gripping portion arranged so as to face an operator side, the spindle being configured to rotatably drive a workpiece gripped by the workpiece gripping portion, and a tool mount equipped with a rotary member supporting a plurality of tools in a rotatably indexable manner about an axis parallel to an axis of the spindle. The tool mount is arranged at a tool mount installation portion formed to be positioned on the operator side in a manner such that the rotary member faces a workpiece gripping portion side.

First claim

What is claimed is:

1. A machine tool comprising:
a bed;
a column being configured on the bed, and including a vertical surface facing an operator;
a spindle being supported on the vertical surface and having an axis being horizontally arranged, the axis extending in a first direction;
a workpiece gripping portion configured on the spindle at an operator side thereof, the spindle being configured to rotatably drive a workpiece gripped by the workpiece gripping portion;
a tool mount installation portion being configured on the bed and on the operator side;
a tool mount being sustained by the tool mount installation portion;
a rotary member being configured on the tool mount, being arranged to face the workpiece gripping portion, and supporting a plurality of tools in a rotatably indexable manner about an axis parallel to an axis of the spindle; and
an operating unit configured on the operator side for the operator to operate,
the tool mount is arranged between the operating unit and the workpiece gripping portion in the first direction,
the rotary member being arranged to face the workpiece gripping portion.

2. The machine tool as recited in claim 1 , wherein the tool mount is arranged so that an axis of the rotary member is positioned below the axis of the spindle.

3. The machine tool as recited in claim 1 , further comprising an indexing motor configured to index the rotary member to a desired angular position,
wherein the indexing motor is arranged below a chip accommodation section for accommodating chips generated by machining the workpiece, and
wherein an output shaft of the indexing motor is connected to a rotary shaft of the rotary member via a power transmission mechanism.

4. The machine tool as recited in claim 1 , further comprising
the spindle is movable in the first direction towards the tool mount.

5. The machine tool as recited in claim 1 , wherein
the spindle is movable in the first direction towards the tool mount, and
a selected tool from the plurality of tools for machining the workpiece is viewable in the first direction from the front.
