Abstract
The frame of a machine tool forms a closed force loop design that surrounds a workzone containing the spindle head. The X and Y-axis drive motors are mounted on stationary elements of the machine. The Y-axis column is fixed, and supports a Z-axis ram. The mounting and positioning of the Z-axis ram minimizes the change in droop and the effects of acceleration forces on the Z-axis structure. The X, Y, and Z-axis drive motors are all mounted outside of the workzone to shield them from contamination and debris generating during the machining process, and for ease of maintenance.
