As machine speed increases the effects of imbalance become greater. Imbalance can severely reduce bearing life as well as cause undue machine vibration. Misalignment /shaft runout - Vibration can result when machine shafts are out of line. Angular misalignment occurs when the axes of (for example) a motor and pump are not parallel.

Tool Holding . Toolholders, whether stationery or rotating, are a vital link between cutting tool, work piece and machine tool. Selecting a holder with a shortest possible overhang and a largest possible diameter is proven solution to minimize vibrations; even custom (i.e. tapered) tool design also works out as an option where setup permits its use.
