Abstract: A machining tool has a tool holder aligned on an axis of rotation ? of its shaft, which axis ? is oblique to the axis of rotation of a spindle at a predetermined angle ?. Accordingly, the machining tool may perform oblique machining of a workpiece. A power transmission mechanism that transmits rotation of the spindle to the machining tool is formed as an attachment to the spindle and includes a rotatable shaft, a second bevel drive gear, a second bevel driven gear, and a feed shaft. Further, a feed mechanism which feeds the machining tool along the axis ? of the rotatable shaft is formed of the attachments, the rotatable shaft; the second bevel drive gear and the second bevel driven gear, a first bevel drive gear a first bevel driven gear, a male screw member, and the feed shaft.
