Abstract
A process for monitoring the correct setting of the coolant nozzle () of a grinding machine for grinding the tooth flanks of workpieces with premachined teeth. In an automatic test cycle after setting the machine, with the grinding wheel () at defined positions relative to the workpiece (), the alterations in power consumption of the grinding spindle drive when switching on the coolant supply are measured, compared with the desired value ranges specified in the machine control system, and the machining process blocked in the event of measurements being below or above the desired value ranges. In this manner the production of scrap and the occurrence of deflagration of the coolant/lubricant-air mixture in the machine working area, and hence a machine fire, can be effectively prevented.
