Claims14
A spindle for a glass drilling unit including one or more decks with a gear train within said one or more decks and a driver for rotating the gear train comprising:
- a body member;
- means adapted for removably coupling said body member, said removable coupling means coupled with one of the decks of said glass drilling unit;
- shaft means adapted for receiving and rotating a drill, said shaft means removably, rotatably coupled with the gear train of said drilling unit;
- and
- means adapted for providing a coolant to a workpiece, said means for providing a coolant directly coupled with said spindle shaft means.
A spindle adapted for use in a glass drilling unit including one or more decks with a gear train within said one or more decks and a driver for rotating the gear train comprising:
- a body member;
- means adapted for removably coupling said body member, said removable coupling means coupled with one of the decks of said glass drilling unit;
- shaft means adapted for receiving and rotating a drill, said shaft means adapted to be removably rotatably coupled with the gear train of said drilling unit;
- and
- means for providing a coolant to a workpiece, said means for providing a coolant integrally coupled directly with said shaft means such that said coolant is passed through said shaft means and ejected onto said workpiece.
The spindle according to claim 5 further comprising sealed bearing means for enabling rotation of said shaft means in said body member and for preventing said coolant from entering said body member.
A drill head comprising:
- one or more decks;
- a gear train within said one or more decks;
- a driver for rotating said gear train;
- and one or more spindles removably coupled with said one or more decks, each of said spindles including:
- a body member;
- means for removably coupling said body member with said one or more decks;
- shaft means for receiving and rotating a drill, said shaft means including means for removably rotatably coupling said shaft means with said gear train;
- and
- means for providing a coolant to a workpiece, said means for providing a coolant integrally coupled directly with said shaft means such that said coolant is passed through said shaft means and ejected onto said workpiece.
