ABSTRACT:
A transmission mechanism for a milling device and an improvement in a ram type milling device having a swivel head structure. The ram is movable in opposite longitudinal directions. An auxiliary section is rotatably coupled to the ram for 0.degree.-360.degree. rotation relative thereto. An input head section that carries the output shaft, is rotatably coupled to the auxillary section for 0.degree.-360.degree. rotation relative to the auxillary section and/or the ram. The machine body of the device has a shaft hole formed therein for receiving one of the ends of a milling tool carried by the output shaft. Guide rail and guide feet are also provided for supporting and guiding the milling tool when desired. A milling tool carried therein by this device may be selectively moved in any of six directions or planes, as desired or needed for working on a workpiece.
