Abstract
A structural element for a precision linear a motion system is provided which is extremely light in weight when compared to cast iron structural components yet provides the necessary rigidity and stability. The structural element is constructed from at least one sheet of sheet material sheared and bent to form the side walls of the structural element which run parallel to a longitudinal axis of the structural element. End surfaces of the structural elements are formed by a flat piece of sheet metal having a shape matching the shape of the side walls and having side sections each of which is spot welded to the inside surfaces of the side walls. Baffles, identical in shape to the end surfaces, are positioned at spaced locations in the longitudinal direction of the structural element. The components of a way system are accurately mounted in a precise alignment by placing the components on layers of any epoxy material which has a high compressive modulus when cured and low shrinkage while curing. The layer of epoxy material, in turn, is placed on an exterior surface of one of the walls of the structural element. The use of the epoxy material avoids uneven mating of the components.
