To improve the quality of the teeth, obtained by both hobbing and slotting, on the gears and the shafts as well with cylindrical toothing (straight or helicoidal) a finishing operation is carried out using a tool, with a defined geometry, called "shaving machine". The shaving machine is a tool geometrically similar to a toothed wheel in which, along the teeth, grooves containing the cutting edges are obtained. The processing takes place through the meshing of the shaving machine with the teeth to be finished, with axes out of square in order to create a sliding in the point of contact which allows the removal of material. The shaving allows to obtain an excellent quality both in geometric and roughness terms.
DEMM is equipped with manual loading shaving machines.
