Broaching of 4 Ø240H7 housings corresponding to the 4 fixed shafts acting as support for the rocker arms, in the Schuler press capital. For the machining, the shaft line resulting from the two centers of the internal housing will serve as reference for the tool positioning, so as to obtain 4 machined housings with a concentricity of less than 0.05mm in relation to this reference line.
