1997 Weingartner Finish 320-7000 CNC Spiral Finishing Lathe

The 1997 Weingartner Finish 320-7000 CNC Spiral Finishing Lathe is a highly precise machine designed for finishing and sizing long bores. It features a 12.6-inch maximum polishing diameter, a part capacity of up to 275 inches, and a quill with 8.6-inch diameter that delivers adjustable polishing action via an 45° swivel polishing head. Centralized lubrication, a chip conveyor, and a protective polishing head enclosure ensure reliable, high-volume production.

Compared to conventional lathes, the Finish 320-7000 stands out by delivering continuous spiral hone finishes in one setup. Its stroke-controlled cross slide (2–6 inches), paired with programmed plunge and stroke parameters, maintains tight tolerances through complex bore geometries—ideal for parts requiring superior surface quality and dimensional consistency using integrated in-process corrections.
