Abstract

A machine tool which removal-machines a workpiece by a tool includes an in-machine robot provided in a machining chamber, and a cleaning mechanism that cleans the in-machine robot by removing an adhering substance adhering to the in-machine robot. When the in-machine robot is cleaned, the in-machine robot moves relative to the cleaning mechanism and positions in proximity to the cleaning mechanism.

First claim

The invention claimed is:

1. A machine tool that removal-machines a workpiece by means of a tool, comprising:
a workpiece spindle device that holds the workpiece;
a tool spindle device that holds the tool that removal-machines the workpiece;
a robot provided in a machining chamber; and
a cleaning mechanism that is disposed inside a recess defined in a side of the machining chamber and cleans the robot by removing an adhering substance which adheres to the robot, the recess being sized such that at least a part of the robot enters the recess, wherein
when the robot is cleaned, at least a part of the robot moves relative to the cleaning mechanism and enters the recess, and
the cleaning mechanism cleans the at least a part of the robot that is located in the recess.

2. The machine tool according to claim 1 , wherein
the cleaning mechanism is fixedly placed in the machining chamber,
the robot can move and change its orientation in the machining chamber, and
when the robot is cleaned, the robot moves and changes the orientation to change a location of the robot to be cleaned by the cleaning mechanism.

3. The machine tool according to claim 1 , wherein
the cleaning mechanism ejects fluid with respect to the robot, to remove the adhering substance.

4. The machine tool according to claim 1 , wherein
the cleaning mechanism contacts at least one of the robot and the adhering substance, to remove the adhering substance.

5. The machine tool according to claim 1 , wherein
the cleaning mechanism cuts and fractionates the adhering substance.

6. The machine tool according to claim 1 , further comprising:
a cover which covers an inside of the machining chamber.
