Abstract of the Disclosure The present invention discloses a method and a device for preventing thermal damage of workpieces due to heat developed by a grinding process. According to the method the temperature increase at the surface being ground is determined and the resulting actual value is compared to a reference value which has been established under the same grinding parameters with a grinding disk that caused thermic damage to the reference workpiece. During manufacture, the grinding process with the respective grinding disk is interrupted as soon as a temperature increase has been detected that corresponds to the respective temperature causing thermic damage. The reference value is determined such that it includes a certain safety margin. The determination of the actual value and the reference value may be accomplished by using geometric deformation of the workpiece that result from the temperature increase due to the grinding process. The device is characterized by special measuring devices for measuring the geometric deformations of the workpieces.
