Abstract
The frame of a machine tool forms a closed force loop design that surrounds a workzone containing the spindle head. The X, Y, and Z-axis drive systems are all mounted outside of the machine to shield them from contamination and debris generating during the machining process, and for ease of maintenance without having to enter the machine or remove workzone covers to access them. The X and Y-axis drives are mounted on stationary parts of the machine, eliminating the need for flexible cables to power and control these drives and reducing the mass of the moving elements of the machine.
