Abstract: The present invention provides an improved nozzle assembly for deriving the final focus of a laser beam for a fine precision cut. A dial is integrally coupled to a nozzle body and a focusing lens group housing. The dial can be rotated in a clockwise or counterclockwise direction along its own axis. As the dial is being rotated, the dial's rotary motion engages the focusing lens group housing to also rotate on its own axis, and the focusing lens group contained within the housing can therefore be appreciably raised or lowered, significantly aiding the final focus. The dial has units of measurement that can be used to track the rotational position of the final focus. Similarly, the height indicator contains a micrometer that registers the final focus such that it can be recorded and replicated.

Abstract: A system and enclosure for cutting or welding a workpiece has a laser beam to effect the cut or weld which can be focused about a Z-axis, and controlled for movement relative to the workpiece about an A (linear) and B (rotary) axis. The workpiece is held for movement relative to the beam about an X (linear) and Y (rotary) axis.

Abstract: The present invention provides an improved system for producing metal stents with a fine precision structure cut from a small diameter, thin-walled, cylindrical tube. The tubes are fixtured under a laser and positioned utilizing a computer-generated signal to move the tube in a very intricate and precise pattern around an X, Y, A and B axis relative to the cutting beam, which is focused by movement relative to a lens along a Z-axis. The stent is cut from small diameter tubing held between a collet and clamp, one of which is periodically opened and the other reciprocably moved to position a small length of tubing, sequentially beneath the cutting head. A water system is incorporated in the apparatus to remove debris falling into the interior of the cut tube and to push discrete portions of the cut tube (or stents) into a parts catcher to separate the stent from the uncut portion of the tube.
