Title: Formed dressing method of ultra abrasive grain wheel
Inventor: ITOU KIMIYOSHI
IPC: B24B53/00
Filed: 1984-01-17
Abstract: PURPOSE:To promote the accuracy of formed dressing of an ultra abrasive grain wheel, by rotating a dresser wheel of general abrasive grain, which copies the profile of a master wheel, by an independent driving power source and bringing the dressor wheel into contact with the ultra abrasive grain wheel on the same grinding board to these wheels. CONSTITUTION:After an ultra abrasive grain wheel 1, dresser wheel 2 and a master wheel 3 are set so as to be rotated by an independent driving power source at an optional peripheral speed, the master wheel 3 is moved while being rotated at a peripheral speed 1/100-1/5 times as fast as the dresser wheel 2 in its direction and brought into contact with the dresser wheel 2, and the profile of a peripheral surface of the master wheel 3 is copied to the dresser wheel 2. Then the ultra abrasive grain wheel 1 is mutually brought into contact while being rotated at a high speed with the dresser wheel 2 by rotating it at a low speed by the independent driving power source. In such way, an ultra abrasive grain, colliding against a general abrasive grain of hardness smaller than the ultra abrasive grain, causes fine destruction forming a sharp cutting edge, while the ultra abrasive grain wheel 1, being brought into contact with the dresser wheel 2 in a condition left as set on a grinding board 4, can be accurately dressed and trued eliminating a setting error.

High-pressure air is put into the upper portion of a cylinder 102 and the piston 106 is moved downward until the piston comes into contact with the catch member 154. The catch member 154 is moved upward by a spring washer 168 by as much as the permissible quantity by a bolt 158, by which the piston 106 and the plunger are moved and positioned to the intermediate loading position. When glass is loaded, the high-pressure air is put under the piston 106 and the piston is moved to the top end of the cylinder 102 to return the piston to the pressurization position. Since the positioning unit 140 is removable as a unit from the cylinder 102, the adjustment thereof is easy.
