Abstract
A machine tool having a main spindle head and an indexing table those being inclined with respect to a horizontal plane. The machine tool comprises the main spindle head, a main spindle, a reciprocation drive means and the indexing table. The main spindle is provided with a tool mount portion at one end portion thereof for mounting a tool, and the reciprocation drive means drives the main spindle head in an axial direction of the main spindle. The indexing table mounts thereon a workpiece and is angularly rotatable about its central axis. Further, an indexing apparatus is also disclosed. The apparatus comprises a base frame, an indexing table, an indexing shaft, a single drive source, a drive means, a follower member, coupling means and shifting means. The drive means is connected to the single drive source, and the follower member is connected to the indexing shaft and is engageable with the drive means for rotating the indexing shaft about its axis. The shifting means is operably provided for moving said indexing shaft in axial direction thereof in response to the drive means. The axial movement of the indexing shaft provides engagement and disengagement of the coupling means.
