Apparatus for measuring concentricity and parallelization-degree

摘要

PURPOSE: A device for measuring concentricity and parallelization-degree is provided to measure the concentric property and parallelism of first and second objects. CONSTITUTION: A device for measuring concentricity and parallelization-degree comprises a reflecting body, a reflection supporting part(20) and a main body(10). The reflecting body locates in the second object. The reflecting body reflects a part of the incident light in the first reflector. The reflecting body reflects a rest part of the incident light in the second reflecting surface. The reflection supporting part forms the cone supporting the reflecting body and faces the second object. The main body locates in the first object.
