Abstract:
1. A cylindrical internal surface processing apparatus comprising: an internal diameter measuring device configured to measure an internal diameter of an internal cylindrical bore formed in a base member to obtain a measurement result of the internal diameter of the internal cylindrical bore; and a controller including a surface roughening control section and a quality determining section, the surface roughening control section being configured to control operation of a surface roughening equipment to form a rough surface section and an internal diameter measuring surface section on the internal cylindrical bore of the base member, with the internal diameter measuring surface section being smoother than the rough surface section, the quality determining section being configured to determine if the rough surface section is acceptable to allow a subsequent thermally sprayed coating to be applied on the rough surface section based on the internal diameter measurement result obtained by the internal diameter measuring device at the internal diameter measuring surface section of the internal cylindrical bore.
