The Working principle of grinding steel ball skew rolling mill

Two pieces of forging dies with screw holes are cross-preparating with each other rotating in the same direction to drive the workpiece rotating and moving in the against direction, Under the action of the forging die, drawing the length of the work piece rolling into the steel parts.

The Working principle of ring rolling machine

Ring rolling is a hot forming process that produces seamless rings varying in size from a few inches in diameter, and weighing less than one pound, to over 1500 mm in diameter and face heights approaching 450 mm. The process and equipment are similar in principle to rolling mills used for plate. In both processes, the metal is rolled between two rolls, which move toward each other to form a continuously reducing gap. In ring rolling, the rolls are of different diameters.

The process is: It begins with a hollow circular preform that has been upset and pierced, similar to preforms used for ring forging. The preform is placed over the idler or mandrel roll, which is forced toward the drive roll. The drive roll rotates continuously, reducing the wall thickness, imparting the desired shape to the cross section, and increasing the diameter. Contours may be rolled on either the inside surface, outside surface or both.

Metal scrap baling press

Metal scrap baling Presses are suitable for compacting stamping press waste, such as steel, brass, copper and aluminium plates. The machines are available in some sizes, with 2 or 3 compactor steps. With high pressure,push the scrap metal to block.
