Versatile Workholding Workhorses

The Stallion Hybrid trunnions from TrunnionTable.com (Elsmere, KY) allow faceplates and chucks to be installed without removal of the trunnion table for faster part setups, increased productivity and higher quality parts. The versatile workholding workhorses accommodate a variety of vises, fixtures, 3-jaw and 4-jaw chucks and collet chucks for flexible job shop workholding. Two models are available, the Stallion Hybrid 9/20 (9 in x 20 in) designed to hold a 6 in vise and the 9/23 (9 in x 23 in) designed for double or single station 6 in vises. Both sub-plates and quick-change sub-plates are available with quick-change ballocks. Standard baseplates allow the trunnion assembly to be offset to one side of the machine to maximize machine travel. A pneumatic brake, built into the outboard support, provides up to 600 lb of clamping torque, an invaluable feature for shops doing heavy off-center milling and drilling. Hydraulic work-holding packages are also available.

“These fixtures are designed for job shops looking to reduce setups and boost 4-axis machining productivity,” said Stan Martin, the president of TrunnionTable.com. “One customer went from 11 setups on five machines down to six setups on one machine just by adding the hybrid trunnion. It saved them between $50,000 and $60,000 on that job alone.” The U.S.-made trunnions are engineered to bolt on to any machine’s rotary indexer, allowing operators to precisely mill, drill, tap and contour up to three sides of a part in one setup. Heavily-ribbed cast iron construction provides high rigidity and durability, needed to withstand long-term repeated use in demanding shop environments.
