A paint mixing machine having at least two axes for spinning either of a cylindrical or rectangular paint container to mix the paint in the container. The machine includes a stationary base frame carrying a mixing apparatus and an intermediate frame between the stationary base frame and the mixing apparatus. The intermediate frame is connected to the mixing apparatus and the stationary base frame by a plurality of vibration isolators. The intermediate frame includes damping weight to balance the deflection of the damping isolators. The base may also include one or more damping weights.
