Abstract
A machine tool for machining workpieces by motion of a machining tool relative to the workpiece has a worktable and a frame extending above the worktable. An X-axis motion unit is movable along the X-axis in a first range of motion. A first machining tool mount is movably mounted on the motion unit for movement in the Y-axis in a second range of motion, and a second machining tool mount is movably mounted on the first machining tool mount for movement in the X-axis within a third range of motion of lesser length than, and within the length of, said first range of motion. A machining tool is mounted on the second machining tool mount, and drives motors are provided for the motion unit on the frame, the first machining tool mount and the second machining tool mount in their respective ranges of motion and axes. A computer control effects operation of the several drive motors to move the machining tool in the X- and Y-axes and to drive the second machining tool mount more rapidly in the X-axis.
