  a. The blanking of the steel grindng rod is implemented via the sawing machine. The dimensional tolerance would adide by the requirements of the order. After the implementation of blanking, the two ends of the raw material are polished into the R arc via the polishing machine.
b. The surface of the product for the rod mill cannot have the crack, overburning and fissure visible to the naked eyes.
c. The nonstraightness of the product is less than 0.2%. The diameter tolerance ranges from +0mm to -1.5mm. The length tolerance is fro +0mm-25mm. The fracture should be less than 3%.
