jun 26, 2017 ball nose milling without a tilt angle. ball nose end mills are ideal for machining 3-dimensional contour shapes typically found in the mold and die industry, the manufacturing of turbine blades, and fulfilling general part radius requirements.to properly employ a ball nose end mill and gain the optimal tool life and part finish, follow the 2-step process belowinvolve grinding). with lloyds ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just america alone. this article borrows from lloyds research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
the ball mill is powered by a fairly robust DC motor salvaged from a junked printer. It had a pulley for a fine-toothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. the motor was mounted using screws on only one side, which were deliberately left loose. this allows the motor to ball mills are generally used to grind material inch and finer, down to the particle size of to microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
