Surface roughness measurement modulo of the honeycomb and the gauge head null for surface roughness measurement which is used for

摘要

PURPOSE:To adequately measure the roughness of an end surface of the honeycomb which has plural cell walls by tracing cell walls of at least =2 cells by using a probe in a special shape. CONSTITUTION:A honeycomb structure 3 is mounted on a slanting adjustment base 2 so that its honeycomb cut surface whose surface roughness in to be measured faces up. Then the cut surface of the structure 3 is set parallel to the moving direction of the probe 5 by the adjustment base 2 and then the probe 6 which has a specific tip structure is set on the end surface to be mea sured. Then the end surface of the honeycomb structure 3 is traced by the probe 6 through the driving of a driving device 4 to measure its up-down move ment quantity by a probe 5. Then the measured movement quantity is supplied to a control/arithmetic unit 7 nd processed, and the result is recorded on a recording device 8 to measure the surface roughness.
