Process for monitoring the setting of the coolant nozzle of a grinding machine

Process for monitoring the correct setting of a coolant nozzle of a grinding machine, which said grinding machine comprises a grinding spindle with a grinding tool driven by a grinding spindle drive, wherein after setting the grinding machine the power consumption of the grinding spindle drive is measured with and without the coolant supply switched on, and wherein by the comparison of the two measurements the settings of the coolant nozzle is assessed;

• wherein in a measured value for the alteration in power consumption derived from the two measurements is compared with a specified desired value range, and wherein an intervention in the setting process of the grinding machine is prompted if the measured value lies outside the desired value range;
• and
• wherein the desired value ranges of the alteration in power consumption of the grinding spindle drive caused by the switch-on of the coolant supply are specified in a machine control system, and wherein the grinding machine performs the test process in an automatic test cycle.
