Kind Code:
A1
Abstract:
Provided is a technique for detecting clogging in a filter caused by chips more reliably than before. A machine tool capable of machining a workpiece, the machine tool comprising a storage tank for storing coolant, an ejection unit for ejecting the coolant stored in the storage tank toward chips generated through the machining of the workpiece, a filter for removing the chips from the coolant ejected toward the chips, a recovery pump for returning the coolant that has passed through the filter to the storage tank, a first acquisition unit for acquiring a first index value representing the amount of coolant ejected from the ejection unit per predetermined time, a second acquisition unit for acquiring a second index value representing the amount of coolant returned to the storage tank through the filter per predetermined time, and a notification unit for providing notification of abnormality in the filter if a result of comparison between the first index value and the second index value satisfies a predefined abnormality condition.
