Abstract

This machine tool comprises a machining chamber in which machining of a workpiece is performed, and a tool storage chamber in which a plurality of tools are stored. The machine tool is further provided with a partition which partitions the machining chamber and tool storage chamber from one another. The machine tool is positioned on the front side of the machining chamber, and is equipped with a first sliding door that moves in the width direction, and a second sliding door that is positioned on the front side of the tool storage chamber and that moves in the width direction. The first sliding door and second sliding door are positioned in such a manner that one of the sliding doors is positioned on the front side of the other sliding door, and when one of the sliding doors is opened, said door overlaps with the other sliding door.

First claim

The invention claimed is:

1. A machine tool comprising:
a machining chamber for machining a workpiece; a tool storage chamber for storing a plurality of tools;
a frame containing the machining chamber and the tool storage chamber;
a partition wall disposed in the frame, the partition wall extending in a partition wall plane and separating the machining chamber and the tool storage chamber from one another;
a first sliding door disposed at a front side of the machining chamber, the first sliding door being linearly movable in a width direction of the machine tool;
a second sliding door disposed at a front side of the tool storage chamber, the second sliding door being linearly movable in the width direction of the machine tool, and
a virtual straight line extending parallel to the width direction, wherein the first sliding door is configured so as to be movable to an associated open position, wherein access through the front side of the machining chamber is provided after the first sliding door has been moved in the width direction to the associated open position,
the second sliding door is configured so as to be movable to an associated open position, wherein access through the front side of the tool storage chamber is provided after the second sliding door has been moved in the width direction to the associated open position,
the first sliding door and the second sliding door are formed so that one door is disposed on the front side of the other door,
the second sliding door overlaps the first sliding door in front of the machining chamber when the second sliding door is opened,
said virtual straight line extends from the machining chamber, through the partition wall plane, and into the tool storage chamber, and
an opening is formed in the partition wall, and the plurality of tools are movable through the opening for movement between the tool storage chamber and the machining chamber.

2. The machine tool according to claim 1 , wherein
the second sliding door is disposed in front of the first sliding door, and
when the first sliding door is opened, the first sliding door is disposed on an inner side of the second sliding door.

3. The machine tool according to claim 1 , wherein
the first sliding door includes a first window through which an interior of the machining chamber is viewable when the first sliding door is closed,
the second sliding door includes a second window through which an interior of the tool storage chamber is viewable when the second sliding door is closed, and
the window of one of the first and second sliding doors and the window of the other of the first and second sliding doors are formed so as to at least partially overlap each other when the one of the first and second sliding doors is opened.

4. The machine tool according to claim 1 , wherein
the first sliding is configured such that the machining chamber is opened in a height direction, and
the second sliding door has a length in the height direction that extends from a bottom to a top of the frame.

5. The machine tool according to claim 1 , further comprising:
a spindle head arranged in the machining chamber and being movable in the width direction of the machine tool;
a tool magazine disposed in the tool storage chamber; and
a shutter disposed on the partition wall, wherein
the opening is formed above the tool magazine and allows the machining chamber and the tool storage chamber to communicate with each other,
the shutter is formed so as to open and close the opening,
the machining chamber includes a machining area for machining the workpiece and an exchange area for changing a tool,
the exchange area is disposed on one end of the machining chamber in the width direction and is arranged above the tool magazine, and
the spindle head is formed so as to vertically move while the shutter is opened, allowing an exchange of the tool through the opening.
