Abstract
In a laser beam machine tool, the problems of power losses, misalignment, high cost, and other problems associated with moving laser heads are eliminated by using a five-axis table in which a biaxial work holder, capable of rotating and tilting a workpiece is mounted on a three-axis table mechanism. In the three-axis table mechanism, an X-axis table is supported on linear motion bearings in overlapping relationship on a Y-axis table, which is, in turn, supported on linear motion bearings on a vertically movable Z-axis table, which is also supported in linear motion bearings. The X-axis, Y-axis and Z-axis tables are driven by servo motors through ball screws so that backlash is avoided.
