CUTTING DEVICE FOR ADJUSTMENT OF RESONANCE FREQUENCY OF DIELECTRIC RESONATOR

摘要

PURPOSE:To attain a quick and highly accurate cutting process for a dielectric resonator by controlling the position of a cutting blade or a stage based on the detection signal of a vibration sensor so as to enable the cutting blade to cut the ground surface of a dielectric substance of the dielectric resonator in the prescribed depth. CONSTITUTION:A vibration sensor 9 detects the ultrasonic vibrations and sends a detection signal to a controller 10. The controller 10 receives the detection signal and knows the time point when the tip of a cutting blade 6 reaches the ground surface of a dielectric substance. Based on this time point, the controller 10 controls the position of the blade 6 or a stage 8 in order to cut the surface of the dielectric substance in the prescribed depth. Then the blade 6 or the stage 8 is laterally moved by a prescribed distance to delete the prescribed number of electrodes. Thus the dielectric substance can be cut in a prescribed amount with high accuracy. Then the adjusting accuracy is improved for the resonance frequency of a dielectric resonator.
