Automatic sharpener for chain-saw chain

An automatic sharpener for cutting teeth of a chainsaw chain including links and cutting teeth having a depth limiter, the sharpener comprising:

• an accommodation area comprising a chain support able to receive the chainsaw chain, a longitudinal axis of the accommodation area defining a first horizontal direction, a median plane of the chain parallel to lateral surfaces of the links defining a vertical plane, a drive means for a preferably automatically forward-regulated and stepwise-regulated horizontal translation of said chainsaw chain received in the accommodation area, a sharpening means arranged to sharpen the cutting teeth at different sharpening angles, after each translation of the chainsaw chain, and a means for planning the depth limiter of a cutting tooth, the planning means and the sharpening means respectively comprising a flat file and a round file removable fixed in a file holder, wherein, the sharpening means and the planning means are arranged to simultaneously sharpen and plane the same cutting tooth in a linear and reciprocating movement of the file holder in a plane comprised between +/−10 relative to the first horizontal direction, and the automatic sharpener further includes a means for vertically positioning the file holder arranged to exert, in the vertical direction, a planning pressure of the flat file on the cutting tooth during the linear and reciprocating movement of the flat file simultaneously with the linear and reciprocating movement of the round file.
