Device for automatic tool change on workpiece of machine tool uses stop mechanism to operate tool change device and clamping device through linear movement of spindle

摘要

The tool change device (3) which moves the tools between the work spindle (1) and magazine (4), and the clamping device (5) which is integrated in the spindle and detachably fixes a tool therein are operated through the linear movement of the spindle via a stop mechanism (7).
