Abstract
PURPOSE: To prevent the damages of tools or tool holders and establish the automatic control of tool replacement timing by interrupting the feed of tools by the output signal of a reverse load detector provided for a control unit.
CONSTITUTION: The controller of a copying lathe comprises a reverse load detecting unit 39 which detects the occurrence of a reverse load by processing a motor speed command signal 40 inputted to a one-way controller 32 and a detecting signal 41 of a DC motor 1. Normally, a sequence circuit 42 provides a contactor changing circuit 33 changing command by processing signals sent from limit switches 5, 6 and 7 attached to the tool head 4. When a signal is given by the reverse load detecting unit 39, a command signal is sent to a speed changing circuit 38 or the contactor chaning circuit 33 to stop or return to the original position the tool head 4. Thus the damage of tools or tool head are prevented from occurring and at the same time, the tool replacement timing is automatically determined.
