Trunnions for vertical machining centers

Horizontal index trunnions from Royal Machine and Tool Co., Berlin, Conn., (www.royalworkholding.com) provide access to three sides of workpieces. Trunnion fixtures are manually or automatically indexed by machine control, and the workholding systems hydraulically clamp. Trunnions, mounted on either side with Royal's 4-in. self-centering, self-contained hydraulic chucks, provide individual clamping control for each part.
