KCP Air Gauges
KCP Air Gauges are indispensable tool for precision batch and mass production. As tolerances have gotten tighter on the shop floor, air gauging is often the only way to make the check fast and easy for the operator.
Air gauge system is a non-contact gauging system and thereby it has longer life due to minimal frictional wear.
Two setting masters ensure linearity online as well as magnification.
KCP offers a wide range of Air gauging with provision of 2 jets, 3 jets & 4 jets configurations to air probes making it best suitable for internal as well as external dimensions, average diameter, taper, ovality & face run-out.
Air gauges are also suitable for checking relative dimension such as flatness, parallelism, center distance, squareness & concentricity.
