Limiting device Range is a simple and cheap system to make conical and conometric milling. Range has a limiting device to allow the inclination amplitude of the plate between predetermined values, from 0° to 12°, in all directions. The rotation of a threaded ring nut, situated under the model holder plate, increases the maximum available inclination of the model of 2° for each turn. It is possible to mount on the model holder base Range the universal model holder plate A54/PR (Range/M version) or the plaster setting plate (Range/G version, shown in the sideways picture
