Automatic on / off control of main shaft and coolant of CNC machine tool

摘要

The present invention relates to a computerized numerical control (CNC) machine tool for automatically stopping automatic operation in order to check a machining state of a workpiece and a tool state during automatic operation, Off control of a main shaft and a cutting oil of a CNC machine tool capable of turning on / off the main shaft / cutting oil off relay, Wherein the contacts of the oil relay are connected to the power line of a coolant oil drive motor and the contacts of the main shaft positive relay and the main shaft reverse relay are connected to the main shaft of the main shaft drive device, It is connected to the forward power supply terminal and the main axis reverse power supply terminal, When the axis reverse relay and the main axis reverse relay are turned off, the power of the coolant drive motor and the main shaft drive motor is cut off.
