The invention belongs to the technical field of diagnosis methods, and relates to a lubrication diagnosis method for a lathe spindle. The lubrication diagnosis method comprises the following steps that S1, the lubrication diagnosis device is installed, specifically, a heating expansion column is fixed to an installation base and connected with a bearing through a heat conduction piece, and the lower end of the heating expansion column faces the upper end of a grease bag; a displacement sensor is fixed at the lower end of the heating expansion column and is connected with a controller; s2, lubrication diagnosis: when the heating expansion column extends, a displacement sensor sends a signal, and a controller judges that a fault occurs; when the heated expansion column continues to extend to abut against the grease bag, the displacement sensor sends a signal to the controller, the controller records the initial displacement H0, after a preset time t1, the controller compares the real-time displacement H1 measur
