ABSTRACT:
A lathe cutter and chip fan is described in which an annular frame includes a rotary portion that is driven to rotate about an axis. The rotary portion is annular, forming a workpiece receiving opening. A cutter is mounted on the rotary portion and projects into the workpiece receiving opening. The cutter rotates with the rotary portion to cut material from a workpiece positioned within the workpiece opening. A housing forms a compartment about the rotary portion and cutter, with a central housing opening substantially aligned with the workpiece receiving opening. A chip discharge openly communicates with the compartment and is situated substantially tangentially with respect to a rotational path of the cutter. A plurality of impellers are mounted to the rotary portion for rotation therewith. The impellers are configured to produce an airflow through the housing with intake air entering through the central housing opening and discharging through the chip discharge, whereby chips of workpiece material removed from the workpiece by the cutter may be discharged in the airflow through the chip discharge.
