A stone-working portal milling-edging machine tool contains a traverse with possibility of vertical motion on columns of portal, a carriage with a cutter with possibility of horizontal motion on the traverse and a cart with possibility of motion under the portal along tracks fastened on the bed of machine tool. The traverse is curvilinear in the plan, it is rigidly enveloped by eight spherical bearings and elastically enveloped by a supporting roller and four pressure rollers, which motion is limited by catches and a driving roller with a drive from the first engine, and from the second engine a drive of the cutter is made with possibility of vertical displacement on the guides to the housing of carriage by means of two hydraulic cylinders, which are actuated from a hydro-electric power station. |
