Abstract

A method for operating a machine tool, in particular an angle grinder, including a tool rotatably bringable into operative connection with a driven shaft, the machine tool having a drive device for actuating the driven shaft, a control device for actuating the drive device and at least one sensor device operatively connected to the control device. The method has the following steps: determining a speed value of the driven shaft; determining a speed value of the tool using the sensor device, which interacts with the tool, controlling an output device and/or controlling, in a predefined manner, the drive device via the control device when a difference between the determined speed value of the driven shaft and the determined speed value of the tool is greater than a defined limit value. A machine tool for carrying out a method of this kind is also described.
