Abstract
A surface tracer having a probe to trace the surface profile of a work continuously and read out the shapes of the work to three-dimensional coordinate electrical signals. The probe is rigidly connected with an X-axis slider which is supported on a base through Y- and Z-axis sliders so as to be slidable perpendicular to each other such that the probe can be slided on the surface of the work. The Z-axis slider is suspended from the base by a suspending spring to support the other X- and Y-axis sliders. Between the base and the X-axis slider a return spring for providing returning force to the probe to its original position is adopted. Pressurized air is supplied to the sliding face of each of the sliders to form an air bearing thereon.
