Document Type and Number:
WIPO Patent Application WO/2023/276783
Kind Code:
A1
Abstract:
This coolant supply device for a machine tool comprises: a pump for supplying coolant from a coolant tank; a first pressure sensor; a plurality of branch pipes and valve mechanisms for supplying the coolant to a plurality of supply destinations including a machining unit for a workpiece; and a control circuit that outputs a stop signal to stop machining of the workpiece immediately if the value of the first pressure sensor deviates downward from a preset first allowable pressure range in a specific supply state in which a specific valve mechanism installed on a specific branch pipe leading to the machining unit for the workpiece as the supply destination is opened, and at least one of the other valve mechanisms is closed.
