Abstract
A cylindrical internal surface processing apparatus has an internal diameter measuring device and a controller. The internal diameter measuring device measures 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. The controller includes a surface roughening control section and a quality determining section. The surface roughening control section controls operation of a surface roughening equipment to form a rough surface section and an internal diameter measuring surface section on the internal cylindrical bore. The internal diameter measuring surface section is smoother than the rough surface section. The quality determining section determines 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 at the internal diameter measuring surface section of the internal cylindrical bore.
