Trunnion Rotary Systems Offer Multiple Part Positioning

Monday, October 23, 2006

New Plate and Cube Trunnion Rotary Systems, manufactured by Hardinge (Elmira, New York), offer multiple part positioning. Load up the trunnion with collet blocks, configure with clamping devices, or customize a window box fixture allowing 4-sided part machining to increase your parts production. Maximize productivity by loading up a second plate or cube to have ready to mount when the first set up is finished. In this fashion, multiple parts can be machined efficiently with the same tool before going to the next tool.

Plate and Cube Trunnions are made of free-machining steel for ease of milling, drilling and slotting by the customer to meet individual set up requirements. The combination of a rugged bearing spindle indexer and a permanent robust bearing pillow block assure rigid, accurate positioning. Hardinge 5C, 16C and 3J Rotary Systems are fully automatic, programmable rotary positioning devices that can be connected to a wide variety of host machines.

The Cube Trunnion is available for, or with, a Hardinge 16C/3J High-Precision Rotary System and provides four 4" x 19" (101.6 x 482.6 mm) mounting surfaces. The square tubing can easily be configured for highly productive 2D work, taking advantage of the fast 300 degree-per-second speed of the indexer, with full revolution available.

Plate Trunnions are available for, or with, a Hardinge 5C or 16C/3J Rotary System. They have an adjustable, multi-position centerline to accommodate various part heights. The 5C Plate Trunnion mounts using a collet-style face plate, and has a 1" x 5" x 12" (25.4 x 127.0 x 304.8 mm) two-sided mounting surface. The A2-5 Plate Trunnion bolts on the indexer's spindle nose and has a 1" x 8" x 19" (25.4 x 203.2 x 482.6 mm) two-sided mounting surface. 5C pneumatic, fail-safe collet blocks easily mount to the plate to accept collets, expanding collets or step chucks.

Plate and Cube Trunnions can be field installed to an existing Hardinge Rotary System. Custom manufacturing is available. For more information call 800-510-3161, or visit
