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.
Claims21
A drilling system comprising a body member, a cutting head at the front end of the body member, the cutting head having at least one cutting edge associated therewith, the body member having a hollow interior running therethrough and at least one opening adjacent the cutting head, a fluid containment system positioned exterior to the body member and forming in association with the body member at least one sealed channel exterior to the body member to provide a coolant fluid to the area of the at least one cutting edge, and a vacuum connected to the hollow interior to apply vacuum pressure through the hollow interior, with at least one air intake channel formed on the exterior of the fluid containment system to supply air into a hole being drilled with the drilling system.
A drilling system comprising a body member, a cutting head at the front end of the body member, at least one cutting insert attachable to the cutting head to provide at least two cutting edges extending from a position along the rotational axis of the drilling system, the body member having a hollow interior running therethrough and at least one opening adjacent each of the at least two cutting edges, a fluid containment system including a fluid containment sleeve and a coolant inducer sleeve, the fluid containment system attached to the exterior of the body member and forming in association with the body member at least two sealed coolant channels positioned to provide a coolant fluid to the area of the at least two cutting edges, and a vacuum connected to the hollow interior of the body member to apply vacuum pressure through the hollow interior, wherein the body member and the fluid containment sleeve rotate together when a hole is being drilled by the drilling system.
A drilling system comprising a body member having a first end and a second end, a cutting head at the first end of the body member, the cutting head having at least one cutting edge associated therewith, the body member having a hollow interior running therethrough and at least one opening adjacent the first and second ends, a fluid containment system positioned exterior to the body member and forming in association with the body member at least two sealed channels exterior to the body member to provide a coolant fluid to the area of the cutting head, and a vacuum connected to the hollow interior to apply vacuum pressure through the hollow interior, with at least one air intake channel formed on the exterior of the fluid containment system to supply air into a hole being drilled with the drilling system, wherein the body member and the fluid containment system rotate together when the hole is being drilled by the drilling system.
