    The CNC Mill can machine many different materials examples are steel aluminum brass copper and plastic. A Mill is not designed for cutting wood and should not be used for that. Examples of operations that can be made in a CNC Mill is to cut a profile shape engrave text mill a 3D surface drill holes and mill bearing pockets. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight.

    milling operations with the appropriate fixture. This type of lathe can handle workpieces up to 25 inches in diameter and up to 200 inches long. However the general size is about a 15-inch swing with 36 to 48 inches between centers. Many tool room lathes are used for special tool and die production due to the high accuracy of the machine. Working principle of Grinding Machine The working principle of a grinding machine is quite easier to understand.. In a grinding machine there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley.. So when we start the electric motor the motor rotates at a certain rpm (150-15000 RPM it may change according to the types of grinding
