(a)ball-bearings are formed into initial round shape by a forging process; this is followed by a grinding process in a specially formed grinding die to get extremely good diameter control (≤ 15µm). (b) Knives are made from forged steel; the steel is then hardened; finally, a grinding operation is used to give a sharp cutting edge.
Ball milling. Ball milling is a grinding method that grinds nanotubes into extremely fine powders. During the ball milling process, the collision between the tiny rigid balls in a concealed container will generate localized high pressure.

Steel balls produced for the bearing industry are often made in standard bearing steel 100Cr6 – AISI 52100 (HRC = 60-66) and are produced through a standardized process, of which grinding is a key operation. The diameter of balls range from very small (0.05mm) to large (300 mm), with a majority of 20-30mm. RAW MATERIAL
in characteristics of the solid materials in the grinding process. Kano et al.8) found that it was the impact ener-gy of the balls that has a large effect on the grinding. Rocking mills (ball mills where the pot is rocked while rotating) are used to prevent adhesion and solidi-fication of .
The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive wide acceptance. High-pressure roll presses
an automatic grinding ball loading system named Magoload. Therefore, ball load could be kept constant by using direct measurement. This article describes the Sensomag and presents some of the major improvements that can be achieved with it. Some other promising avenues are still to be explored.
