Abstract
Disclosed is a device for accurately indexing a worktable which carries a workpiece thereon upon which work operations are to be performed. The worktable is moved intermittently to successive locations by a pneumatic cylinder under the direction of a program device movable with the worktable. A control device, in its preferred form being a pneumatic logic circuit, reads the program device to actuate the cylinder in accordance with the program, locks the worktable at the desired position, actuates the machine operations, and otherwise directs the entire operation on the workpiece.
