Double Disc Grinding  press is a common friction presses for ferrous and ferrous metal forging, extrusion, cutting, bending, correction and refractory molding products and so on. The machine has a simple structure, energy, low noise, long life, safe, reliable, easy to maintain. Widely used in aviation, automobiles, tractors, tool manufacturing, textile machinery and other industries. In the history of industrial development has made important contributions. However, because the double-disc friction press at runtime is to use the contact friction plate and flywheel power transmission, other than action in the fight against time, energy wasted. So because of its severe energy loss, has long been listed as "out of class machinery and equipment." [
