The invention relates to the technical field of machine tool equipment monitoring, in particular to a machine tool cutter damage monitoring method and device and a machining center. The method comprises the steps that a load characteristic value of a main shaft in the machining process is obtained in real time, the current load characteristic value is compared with a load normal characteristic value, and load difference data obtained through comparison of the current load characteristic value and the load normal characteristic value is obtained; if the load difference data exceeds a preset load difference threshold value, it is considered that the load of the spindle is abnormal at the moment, and a load abnormal signal is output. And the cutter can be correspondingly processed based on the abnormal load signal of the main shaft. According to the method, the state of the cutter in the machining process can be monitored in real time, the real-time performance of cutter state monitoring is improved, the state o
