A balancer swivel arm assembly includes an articulated arm configured to be pivotably attached to a work station at a proximal end. A linear slider is slidably mounted on a distal end of the articulated arm. A spring balancer is mounted on the distal end of the articulated arm and is coupled to the linear slider. The spring balancer is configured to support the linear slider and a tool mounted to the linear slider through a linear range of motion along an axis.
