DETAILED DESCRIPTION OF THE INVENTION The present invention provides a machine tool, in particular a magazine body for holding a plurality of tools, in which a tool storage magazine is installed on the side of a column that guides and supports a spindle head that supports a spindle in a vertically movable manner. The tool storage magazine is guided so that it can move forward and backward relative to the spindle, moves the magazine body toward the spindle when changing tools, and retracts the magazine body to a position where it does not interfere with the movement of the spindle after the tool change is completed. This relates to machine tools equipped with

In the case where a tool storage magazine is installed on the column side, when changing tools without using a tool changer, the magazine body holding a plurality of tools is guided and supported so that it can move forward and backward with respect to the main axis of the machine tool, When changing tools, it is necessary to move the magazine body toward the spindle, and after the tool change is complete, it is necessary to retract the magazine body to a position where it does not interfere with the movement of the spindle. If this retracted position is close to the spindle, the workpiece There is a risk that chips scattered during machining may adhere to the taper fitting surface of the tool held in the magazine body, making it impossible to mount the tool on the spindle in the correct orientation.

For this reason, it is better to move the magazine body back as far away from the spindle head as possible, but if you do this, not only will the moving stroke of the magazine body become large and the machine become larger, but also the magazine body will need to be moved when changing tools. There is a problem in that it takes time to move forward and backward, and the time required to change tools becomes longer.

In order to solve the above problem, the present invention provides an opening/closing cover on the magazine body side to shield between the tool holder and the main shaft.
This opening/closing cover is opened when the magazine body is moved toward the main shaft, and closed when it is in the retracted position, so that it will not scatter even if the magazine body is moved as close as possible to the main shaft. To provide a machine tool which is free from the influence of powder, and therefore reduces the forward and backward stroke of the magazine body and shortens the tool change time.
