在超硬磨料砂轮的修整中，采用了较低的爆破压力和较低浓度磨粒浆液的湿法喷砂，可称之为温和湿法喷砂。较低的爆破压力和较低的泥浆浓度可使磨粒恢复其切削刃，并使粘结材料不受爆破颗粒的损坏。用于该修整方法的设备包括在相当低的压缩空气供应下工作的喷枪，以及以低浓度磨粒向喷枪输送浆液的浆液输送装置。

WET BLASTING WORKING WITH RATHER LOW BLASTING PRESSURE AND WITH SLURRY OF LOW CONCENTRATION OF ABRASIVE PARTICLES, WHICH MAY BE CALLED GENTLE WET BLASTING, IS APPLIED TO DRESSING OF SUPERABRASIVE GRINDING WHEEL. LOW BLASTING PRESSURE AND LOW CONCENTRATION OF SLURRY BRING A GOOD RESULT FOR ABRASIVE GRAINS TO RECOVER THEIR CUTTING EDGES AS WELL AS FOR BONDING MATERIALS WHICH ARE NOT TO BE DAMAGED BY BLASTING PARTICLES. THE APPARATUS FOR THIS DRESSING METHOD COMPRISES THE BLASTING GUN WORKING WITH A SUPPLY OF RATHER LOW COMPRESSED AIR AND THE SLURRY TRANSPORTATION DEVICE WHICH SENDS SLURRY TO THE BLASTING GUN IN LOW CONCENTRATION OF ABRASIVE PARTICLES.
