MILLING OPERATIONS TYPES OF MILLING MACHINES
Plain milling cutters that are more than 3/4 inch in width are usually made with spiral or helical teeth. A plain spiral-tooth milling cutter produces a better and smoother finish and requires less power to operate. A plain helical-tooth milling cutter is especially desirable when milling an uneven surface or one with holes in it. Types of Teeth

SIZE REDUCTION
At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.

The Development and Characterization of a Ball Mill for Mechanical
For this goal, we report on the development and the characterization of a ball mill for use in mechanical alloying. In this design, a magnetic field is introduced to the ball mill [1]. Various modes of a controllable and reproducible operation may be obtained through the adjustment of the applied magnetic field. The improved ball mill used here has a cylindrical chamber 12.5 cm in diameter and
