Abstract
PURPOSE: To maintain the dimensional accuracy of a work in uniform for a long period of time by a method wherein a temperature in a grindstone guard is controlled in constant to keep a thermal expansion of a grinding wheel in stable all the times.
CONSTITUTION: When the work is ground to a predetermined dimension, a grindstone stand retreating signal is outputted and the grindstone stand 13 is retreated to an original position. A control valve 26 is switched in accordance with the retreating signal and pressurized air is supplied to an air nozzle 23 from a pressurized air supplying source 25 to inject the air into a grindstone guard 17. Thereby, a working heat accumulated in the grindstone guard 17 by grinding is discharged to outside of the grindstone guard 17 with the air and an internal portion of the guard 17 is cooled. When the internal portion of the guard 17 is cooled to a predetermined temperature, a signal generating device 22 is operated in accordance with an output from a temperature sensor 20 to output a control signal. The control valve 26 is switched into an original position in accordance with the signal and the injection of the pressurized air from the air nozzle 23 is stopped.
