Focus Assembly Upgrade Accessory - 4 in. model
Features and Advantages
Get Quality in a New Dimension with a state-of-the-art laser cutting/engraving head upgrade accessory for your Laser Engraver/Cutting Machine. Laser Cut wood/plastics at a faster rate (sonic velocity air exits nozzle with laser beam). Less burn back in your laser cut parts, otherwise stated, reduced Heat Affected Zone (HAZ). New capability to fine tune your laser cut: Adjust nozzle standoff from material while maintaining the same focal distance (improves air flow). Permits focusing at top, middle, and bottom of material.

Click here for article on Laser cutting of different polymeric plastics (PE, PP and PC) by a CO 2 laser beam. The authors say, "In the nozzle employed for cutting plastics, the gas jet orifice has a 0.8 mm diameter. Its function is to discharge gas coaxially to the laser beam. The extremely small size of the orifice ensures a thin, punctiform and efficacious jet of gas that makes it possible to obtain the narrowest possible kerf width and, simultaneously, high operating speed thanks to the rapid removal of the molten material. The nozzle–sample distance was fixed at 1 mm, because at this distance it is possible to obtain an optimum gas jet convergence and pressure in the cutting channel."
Impractical for smaller machine laser engraving and cutting, however, the physics of laser cutting flow dynamics can be carried over from metals to plastics. In other words, failures in nice cuts on plastics can turn in to successes with the right nozzle and air pressure. See these metal cutter industry leaders with their automatic nozzle changers.
