Abstract
A drilling byproduct recovery system employs a vacuum shroud positioned adjacent a workpiece. A spindle extends from a base and engages a tool. The spindle vertically reciprocates the tool upwardly through an aperture in the vacuum shroud to engage the workpiece. A circumferential air jet is emitted proximate a base of the spindle and directed toward the vacuum shroud.
Claims20
A machining byproduct recovery system comprising:
- a vacuum shroud positioned adjacent below a workpiece;
- a spindle vertically separated below the vacuum shroud, extending from a base and engaging a tool, said spindle vertically reciprocating the tool upwardly through an aperture in the vacuum shroud to engage the workpiece;
- and
- a circumferential air jet emitted proximate the base of the spindle vertically spaced below and directed upwardly toward the vacuum shroud to a focus proximate an operational termination of the tool and encircled by the vacuum shroud thereby urging drilling byproducts upward for capture within a suction pattern of the vacuum shroud to capture byproducts above the spindle.

A method for machining byproduct recovery comprising:
- drawing vacuum through a vacuum shroud positioned adjacent below a workpiece and over a drill spindle assembly;
- directing a circumferential air jet from a base of the drill spindle assembly upward toward the vacuum shroud to a focus proximate an operational termination of a tool engaged in the drill spindle assembly thereby urging drilling byproducts upward for capture within a suction pattern of the vacuum shroud to capture byproducts above the spindle;
- and,
- reciprocating the drill spindle assembly upward through an aperture in the vacuum shroud.
