Critical speed - Wikipedia. In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.
• Revolutions per minute (RPM) – It is a measure of the frequency of a rotation. – It represents the number of turns completed in one minute around a fixed axis. It is used as a measure of rotational ... – ½" end mills should be run at 2000RPM • This is 260 SFM –material controls if this proper speed

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.
