The advantage of skew rolling mill.

The skew rolling is new technology of producing various shafts, compared with common forging, casting and machining, the processes have many remarkable advantages. The productivity is as 3-10 times as that of conventional processes, the material consumption can be reduced by 20-35%, comprehensive mechanical properties of workpieces rolled by the  processes increases about 30%, service life of the dies increases about 10 times, and there is no pound and low noice. The processes apply to produce commercial shafts and balls used in automobiles, tractors, electric motors. and other machines.

The Working principle of grinding steel ball production line

The general principle is simple.                 But if want improve the strength and Impact energy,we will need intermediate frequency furnace and special design. The full process should more complex. 1, Steel billet inspection, cutting into specified lengths as the material 2, Heating the steel billet in the continuous type furnace to the right temperature 3, Hot steel billet will be skew rolled between two rollers with special spiral groove into steel balls,  Its speed is 60-120 balls/min. 4, Hot steel ball go into heat treatment equipment for quenching and tempering, steel ball has high and even hardness by the processing. 5, After inspection, the steel ball will be packed and delivery to client.
