Apparatus for finishing inside diameter of workpiece

摘要

In a finishing apparatus, a plurality of workpieces (41) are retained at spaced distances in a direction of an X-axis. Disposed on a table (175) movable in the direction of the X-axis are a single spindle which is parallel to the axes of a plurality of bores to be finished, and which is capable of being advanced and retracted axially, and a measuring means (51) which can measure an inside diameter of each of the finished bores and which is capable of being advanced and retracted independently from the spindle (47) in a direction along the axis of each of the finished bores. A combination tool (52) is mounted at a tip of the spindle and is capable of finishing an inner surface of any of the bores to be finished.
