Abstract
A vacuum drilling system and methods is provided that may utilize both a through tool coolant supply as well as a central vacuum extraction system. The system may include a cutting head provided on a hollow tube and a vacuum source to apply vacuum pressure to the area of the cutting head via one or more chip inlets arranged proximate to the cutting head. Sealed coolant containment channels supply coolant to the area of the cutting head.
Claims20
A drilling system for performing a drilling operation, comprising generally cylindrical body member, a cutting head at the front end of the body member having at least one cutting edge formed thereon, the body member forming a hollow shaft adjacent the cutting head with at least one opening in the body member adjacent the cutting head, a coolant adapter provided on the body member to provide a coolant fluid through at least one sealed channel in the body member exterior to the hollow shaft, to provide the coolant fluid to the area of the at least one cutting edge, and a vacuum connected to the hollow shaft to apply vacuum pressure through the at least one opening and hollow shaft.
A method of performing a drilling operation comprising providing a drilling tool having a cutting head at a front end of the tool having at least one cutting edge formed thereon, and a hollow shaft with at least one opening adjacent the cutting head, a coolant adapter provided on the body member to provide a coolant fluid through at least one sealed channel in the body member exterior to the hollow shaft, and coupling a vacuum source to the hollow tube to extract cuttings formed at the cutting head.
A drilling system for performing a drilling operation, comprising generally cylindrical body member, a cutting head at the front end of the body member having at least one cutting insert with at least two cutting edges extending from a position along the rotational axis of the drilling system for double effective cutting, the body member forming a hollow shaft adjacent the cutting head with at least one opening in the body member adjacent each cutting edge, a coolant adapter provided on the body member to provide a coolant fluid to each cutting edge through at least one sealed channel in the body member exterior to the hollow shaft, to provide the coolant fluid to the area of each cutting edge, and a vacuum source connected to the hollow shaft to apply vacuum pressure through the at least one opening and hollow shaft.
