ABSTRACT:
An apparatus for machining tubing includes a weighted base, an upright frame attached to the weighted base, and a laser light source attached to the weighted base. The apparatus also includes a guide bushing tooling attached to the upright frame which holds a guide bushing. A rotary drive bushing is aligned with the guide bushing holder. An optical assembly for focusing the laser light to a laser beam spot is also attached to the guide bushing tooling block. Spacer plates may be used to correctly space the optical assembly from the tubing material.
