Abstract:
1. A machining apparatus comprising: a rotatable spindle, a table on which a workpiece is fixably mounted; a machining tool for machining the workpiece and including a rotatable shaft; and a machining tool holding unit mounted on the spindle and to which the machining tool is fitted, the machining tool holding unit including a power transmission mechanism that transmits rotation of the spindle to the machining tool, and a feed mechanism that feeds the machining tool along the axis of the rotatable shaft of the machining tool, wherein the rotatable shaft of the machining tool is positioned on an oblique axis that is oblique with respect to a rotatable shaft of the spindle; and wherein the feed mechanism includes: a bevel gear mechanism having a bevel drive gear which is coaxial with the spindle and which is driven by the spindle, and a bevel driven gear which is provided on the oblique axis and which is driven by the bevel drive gear, and a movement conversion mechanism which converts rotation of the bevel driven gear to straight movement along the axis of the machining tool.
