Abstract

The disclosed embodiments provide a novel and unique apparatus and method to remove swarf from a workpiece during the operation of a machine tool on that workpiece. In a preferred embodiment, a set of slanted vanes attached to a rotating part of the machine tool, when that rotating part is directed at the workpiece, clears swarf from a workpiece during machine operation without having to add any other expensive swarf removal parts, or integrate any complicated swarf removal system into the machine tool. The vanes on the rotating part, using the motion of that rotating part, provide the required force of air to blow swarf out and away from the workpiece. Among the many different possibilities contemplated, the rotating part can be a spindle, or a tool holder, or an endmill, or any other rotating part of a machine tool pointed at the workpiece during the operation of the machine. Additionally, the set of slanted vanes can attach to an inner hub fitted around or onto the rotating part and the slanted vanes can spin free of any other parts if the composition of the vanes with any metallic or non-metallic material make the vanes sufficiently stiff to provide the necessary air force on the workpiece during the operation of the machine and the high speed of the rotating part. Also, the outer edge of the slanted vanes can connect to a shroud surrounding the vanes and thus keep the slanted vanes in the required slanted position to produce the necessary force of air on the workpiece. Additionally, O-rings can be used to fit the inner hub to the rotating part and thus provide another way to create the firm and secure attachment of the machine tool swarf removal apparatus to the rotating part.
