Abstract:
1. A rigid design for a machine tool having perpendicular X, Y, and Z axes, comprising: fixed X-axis frame members; a vertical fixed X-axis wall supported by the X-axis frame members for supporting a workpiece thereon for movement in the X-axis direction; an immovable fixed bifurcated Y-axis column having a center opening; a saddle mounted in the center opening of the Y-axis column; a spindle mounted on the saddle for Z-axis motion in a longitudinal direction of the spindle and perpendicular to a longitudinal face of the X-axis wall; and, rigid structural members connecting the top and bottom of the x-axis frame members to the top and bottom of the fixed Y-axis column, respectively, whereby the X-axis frame members, the Y-axis column, and the rigid structural members form a closed force loop design.
