Talyrond XL employs vertical column that sits on precision-bearing rails and can be adjusted and fixed in radial direction to suit diameter of part under test. Roundness and cylindricity measurement system accommodates parts up to 1,000 mm diam and large-radial-swing components. High-resolution inductive gauge is attached to radial arm with 300 mm of travel, and frictionless air-bearing spindle is mounted onto 3-footed steel base to ensure thermal and structural stability.
