The new Stallion Hybrid trunnions from TrunnionTable.com (Booth #W-2268, IMTS 2016) allow faceplates and chucks to be installed without removal of the trunnion table for faster part setups, increased productivity, and higher quality parts. The trunnions accommodate a variety of vises, fixtures, three- and four-jaw chucks, and collet chucks for flexible job shop workholding.
Two models are available, the Stallion Hybrid 9/20 (9 inch x 20 inch) designed to hold a 6-inch vise and the 9/23 (9 inch x 23 inch) designed for double or single station 6-inch 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 pounds of clamping torque — an invaluable feature for shops doing heavy off-center milling and drilling. Hydraulic workholding packages are also available.
“These fixtures are designed for job shops looking to reduce setups and boost 4-axis machining productivity,” said Stan Martin, 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 save 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.
