A new pencil sharpening machine that is essentially constituted by two main mechanisms that work in coordination and automatically one constituted by the blade or cutting blades that are flat and rotate radially around the main axis and the other constituted by the clamping device of the pencil which is affected by a rotary movement by means of a transmission driven by the same main axis transmitting this movement of rotation to the pencil and guiding it automatically so that its end gets in the path followed by the blades.
