What is an inching drive? - Motion Control Tips

An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically 120 percent of the normal drive torque.

Dynamic Balancing vs. Static Balancing -

An example of dynamic balancing is a cylindrical rotating CNC mill with necessary sections on the interior or exterior of the mill system that create an imbalance on one side of the cylinder. Counterweights built into the cylinder create a system that keeps the mill balanced during dynamic movement, preventing the accumulation of centrifugal force when in operation.
