Pro-Series 2 1/2" - Focus assembly fits Epilog Legend, Helix, Mini and EXT36. Riveting straight cuts.
Regular Price: $289.00
Sale Price: $188.95
Pro-series includes 3 nozzle tips, with different diameter holes to provide flexibility for cut depth penetration and quality. These color coded tips are easily screwed on and off for different material laser cutting needs.
Improved cut quality on nonmetals, especially woods. Reduces charring by pushing smoke and debris down and away from the cut area.
Reduces cut width with focused air stream that pushes smoke and debris away so cutting process performs faster, thus reducing the heat affected area of the cut.
Saves time on cut parts clean-up. With less smoke and debris settling on the face, side, and bottom of the cut, clean-up time is reduced or eliminated.
The Pro-Series works well with autofocus. Simply unscrew the nozzle tip and back to engraving.
The Mahoney brand focus nozzle assembly fits the Epilog Laser Legend series products, including the Epilog Helix, the Epilog Mini 18, Mini 24, and Epilog 24TT. Package includes (1) Assembly + nozzle set ; (2) Air hose
Industry Leaders recommending Laser Nozzles
Click here to read "The Fabricator". These techniques apply to nonmetals cutting, even though the target audience cuts metals. Read: "Setup time for a laser can be lengthy when preparing to cut unfamiliar materials. Nozzle size, power, optical focal length, assist gas, gas pressure, speed, and focal length can all influence the process. These parameters are so important to the process that if they are not set correctly, the material cannot be cut."
Market Leaders identify Laser Nozzles for Higher Quality
Click here for Vytek laser website says (photo included) "FX3 Standard Features: The FX3 system includes our full function cutting and engraving head. This unique assembly allows use of a gas assist delivery nozzle and the choice of focal length optics from 1.5" to 7.5" while still allowing for independent adjustment of the nozzle length as well as centering of the optic within the nozzle orifice. This feature allows the operator to maintain the ideal adjustments for just about any cutting or engraving application."
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.
