The machine functions are controlled by the CNC control system which also enables the machining of the spatially complicated shapes when the tool follows the path resulting from the 3D CAD program output. The machine spindle which is mounted in the spindle unit embedded in the spindle head, moves in the vertical direction (Z-axis) along the guide ways on the column. The work table, whose upper surface serves for the workpiece clamping, moves in the longitudinal direction (X-axis) along the guide ways on the cross saddle. The cross saddle moves along the guide ways on the base in the cross direction (Y-axis). The machine is equipped with the electronic compensation of thermal dilatations.
