the present patent of invention relates to a machine through the control of four axes x, y, z and kallows the handling of a group door tool to achieve linear profiles on coasts and curves of slabs of marble, granite, stone, glass and the like.a wagon "1" that flows across the guide "2" (axis z) carries two sledges. a vertical "3" (y axis) and a horizontal "4" (x axis), commanded by their respective motors (5, 6).a motor 7 through a system wheel helical and lives without end puts in the rotation, the spindle carries tool "8" around its own axis (k) in order to describe an arc of circonferenzfrom m to 350.all the movements of guide door spindle is vertical, transverse and longitudinal guides and screws through recirculation of balls, often without bothering to check what car.oleodinamici cylinders or other similar means of movement.the rotation of the mandrel around the axis (k) allows you to create and polishing toroidal and similar profiles on the shores of linear (using volume plane).the mandrel and locked in an upright position and conveniently moved along the axes x, y and z, allows you to create and polish coast curves (using volume shaped).
