Abstract
A spindle condition detection device for a machine tool includes: bearing load detecting means (16, 17, 20) for detecting a load on a bearing (14) that rotatably supports a spindle (12) of a machine tool; and present usage ratio calculating means (30) for calculating, based on the load detected by the bearing load detecting means (16, 17, 20), a present usage ratio that is a ratio of usage of the bearing (14) with respect to a prescribed operating life of the bearing (14), which is achieved over a period until a present moment.
