The DF-F16 True-Diameter gage is designed to verify part OD automatically in the machine. With a repeatability of better than 0.0004", out-of-tolerance parts can be detected and eliminated from production runs before waste or crashes occur, the company says. The miniature gage is designed for smaller machines and tight work areas. According to the company, it can measure diameters ranging to 16 mm without taking up a position or affecting cycle time, and immediate, automatic actions can be triggered when defects are found.
