Being the shot-ball peening manner which peening treats

摘要

As state of the projection material can be verified while processing the suffering processing product in the method peening of processing the suffering processing product by injecting the projection material due to the compressed air, wear of the sensor is prevented, shot-ball peening method and its device which at the same time can do the maintenance of the sensor, and to assure the decrease of proofreading, are offered. Being the shot-ball peening method peening of processing the suffering processing product with the compressed air by making the projection material the suffering processing product inject from the injection nozzle, in the aforementioned injection nozzle, the elastic wave by the projection material which passes the said injection nozzle detecting it converts to the high frequency electric information and it installs the transmitter which is output, and it measures the status value of the projection material which passes the aforementioned injection nozzle on the basis of the aforementioned high frequency electric information watch.
