ABSTRACT:
A machine tool comprising a spindle head, a tool magazine, and an arm, the arm being secured to the spindle head, the arm having gripping members for holding a tool holder. When a workpiece is machined, the arm in which gripping members are opened is placed near the spindle. As soon as machining is completed, the grip members are closed so as to hold the tool holder set into the spindle. The end face of the spindle and the end face of the tool magazine stand at different levels when the spindle head is located in tool changing position. When a used tool is returned to the tool magazine, the arm operates in the following steps: first, the arm grips the used tool set into the spindle; second, the arm is moved so as to draw the tool from the spindle; and third, the arm is swiveled so as to return the tool to the tool magazine.
