Dressing method and dressing apparatus

A dressing method for dressing a grinding surface, comprising the steps of:

• causing a regulating body conforming to a shape of a grinding surface of a grinding wheel to be brought face-to-face, over a required length, with the grinding surface of the grinding wheel which rotates with resilient force;
• jetting pressurized running water with abrasive grains mixed therein into a space between the grinding surface and the regulating body;
• passing the grinding surface in a rotating direction with respect to the regulating body;
• and
• maintaining a state of application of jetting force of the abrasive grains onto the grinding surface by means of the regulating body during the passage.

A dressing apparatus comprising:

• a regulating body which has a surface having a shape corresponding to a shape of a grinding surface of a grinding wheel, the surface being brought face-to-face, over a required length, with the grinding surface of the grinding wheel which rotates;
• a device for generating a pressure fluid with abrasive grains mixed therein;
• a jetting device for jetting the pressure fluid with the abrasive grains mixed therein into a space between the grinding surface and the regulating body;
• and
• an elastically pulling device for causing the abrasive jetting surface to oppose the grinding surface with resilient force.

A dressing method for dressing a grinding surface while grinding a glass plate, comprising the steps of:

• causing a regulating body conforming to a shape of a grinding surface of a grinding wheel to be brought face-to-face, over a required length, with the grinding surface of the grinding wheel which rotates;
• jetting compressed air with abrasive grains mixed therein into a space between the grinding surface and the regulating body;
• passing the grinding surface in a rotating direction with respect to the regulating body;
• and
• maintaining a state of application of jetting force of the abrasive grains onto the grinding surface by means of the regulating body during the passage.
