Polished Dish End Hydraulic Press Machine for Industrial

Three-roller machines (variable pitch aka variable geometry) have one pressing top roll and two pressing side rolls. The three-roll variable pitch works by having all three rolls able to move and tilt. The top roll moves in the vertical plane and the side rolls move on the horizontal plane. When rolling, the top roll presses the metal plate between the two side rolls. The advantage of having the variable three roll is the ability to roll many thicknesses and diameters of cylinders.
