Dimensional gage with hollow spindle

摘要

A dimensional gage adapted to make measurements on a workpiece has a fixed member, a spindle assembly comprising a hollow spindle which receives the fixed member and is rotatable with respect to the fixed member, a motor which rotates the spindle assembly, and a sensing assembly attached to the fixed member and adapted to measure one or more dimensions of the workpiece. The dimensions may be measured both statically and dynamically, and the sensing assembly can have separate sensor assemblies for each dimension to be measured.
