Abstract
In a bore size correcting apparatus, a passing-through jig of an extended type lapping reamer in the bore size trimming device is passed through the bore surface of the workpiece machined by the bore grinding machine to correct the inner size of the workpiece, either one of the bore size to be corrected and a corrected bore size of the workpiece is measured by the bore size measuring device, a signal is outputted in accordance with the corrected bore size, and in response to the output signal, a machining command is supplied from the bore size control device to at least one of the in-process fixed-size control device and the external size control device. Thus, the bore size of the workpiece roughly manufactured by grinding can be precisely finished, with no skill, so as to have any optional set value, and the correction apparatus is also made compact and inexpensive.
