Abstract
A dresser for a grinder having at least one rotatable platen and at least one grinding stone includes a frame and at least one abrasive block for contacting the grinding stone. The grinding stone is mounted to the platen which rotates about a vertical axis. The abrasive block extends across the grinding stone. The frame of the dresser is mounted proximate the platen and remains stationary while the grinding stone rotates. The abrasive block contacts the rotating grinding stone, thereby dressing the grinding stone.
Claims25
A dresser for a grinder including at least one platen rotatable about a vertical axis and at least one grinding stone mounted to the at least one platen, the dresser comprising:
- a frame mounted proximate the at least one rotatable platen;
- and
- at least one abrasive block coupled to the frame for contacting the at least one grinding stone, the at least one abrasive block extending across a portion of the at least one grinding stone,
- wherein the at least one abrasive block does not rotate when the at least one grinding stone rotates in contact with the at least one abrasive block, the at least one abrasive block thereby dressing the at least one grinding stone.
A grinding apparatus comprising:
- at least one platen rotatable about a vertical axis and including at least one grinding stone;
- a dresser frame removably mounted proximate the at least one rotatable platen;
- and
- at least one abrasive block coupled to the frame for contacting the at least one grinding stone, the at least one abrasive block extending across a portion of the at least one grinding stone,
- wherein the at least one abrasive block does not rotate when the at least one grinding stone rotates in contact with the at least one abrasive block, the at least one abrasive block thereby dressing the at least one grinding stone.
A method of dressing grinding stones on a grinder, the grinder including at least one platen rotatable about a vertical axis and at least one grinding stone mounted to the at least one platen, the method comprising:
- mounting a dresser proximate the at least one platen, the dresser including at least one dressing surface contacting the at least one platen, the at least one dressing surface extending across the at least one grinding stone;
- and
- rotating the at least one platen while the dresser remains stationary to dress the at least one grinding stone.
A dresser for a grinder including at least one platen rotatable about a vertical axis and at least one grinding stone mounted to the at least one platen, the dresser comprising:
- a frame mounted proximate the at least one rotatable platen;
- and
- at least one abrasive block pivotally coupled to the frame for contacting the at least one grinding stone, the at least one abrasive block extending across the at least one grinding stone,
- wherein the frame remains stationary when the at least one grinding stone contacts the at least one abrasive block and rotates, the at least one abrasive block thereby dressing the at least one grinding stone.
A dresser for a grinder including a sun gear, a ring gear, at least one platen rotatable about a vertical axis and at least one grinding stone mounted to the at least one platen, the at least one grinding stone extending between the sun and ring gears, the dresser comprising:
- a frame mounted proximate the at least one rotatable platen;
- and
- at least one abrasive block coupled to the frame for contacting the at least one grinding stone, the at least one abrasive block extending across the at least one grinding stone,
- wherein the frame remains stationary when the at least one grinding stone contacts the at least one abrasive block and rotates, the at least one abrasive block thereby dressing the at least one grinding stone.
