Abstract
A processing apparatus capable of grinding an arcuate groove (a groove having an arcuate shape in section) of various shapes defined in a work with a good accuracy. A pseudo-elliptic arcuate groove defined in a work is ground by a forming grindstone. The work is moved in a Y-axis direction (vertically on a paper sheet) in a state in which the forming grindstone is supported on a tool table for rotation and is moved in a X-axis direction (a direction perpendicular to the paper sheet) to abut against the arcuate groove, while rotating the work in a direction of an arrow with its axis L matched with an axis C of an indexer. Thus, it is possible to relatively move the forming grindstone to trace the arcuate groove, thereby accurately grinding the arcuate groove.
