Apparatus for controlling inner and outer surfaces, of members of mechanics, and utilization of this apparatus

摘要

Method and apparatus for gauging inner and outer surfaces of a member, the member mounted on a table with the surface to be gauged oriented perpendicular to the table surface. Three feelers are disposed above the table. The feelers are adjustable radially in their position depending on the geometry of the member. One of the said feelers is spring biased for radial movement and bears against the said surface. This movable feeler is connected to a comparator indicating its position.
