Date Announced: 12 Dec 2012
To celebrate Christmas, industrial laser manufacturer JK Lasers, has cut a festive tree in 1mm brass with decorative 1mm aluminium snowflakes and 1.5mm red anodised aluminium baubles, using a 1kW fiber laser and Nitrogen assist gas.
Aluminium and brass are highly reflective materials that can be difficult to process using lasers. Light can be reflected back onto the laser and optics, potentially causing damage. Unlike competitors, JK Lasers offers an integrated back reflection protection system that directs the reflected light away from the delivery fibres and into a beam dump. Using this patented system speeds of 12m/min and 11m/min can be achieved when using a JK1000FL to cut 1mm brass and 1mm aluminium respectively.*
JK Lasers’ Christmas message is the last in a series of six laser processed messages, designed to celebrate special events throughout the year. Each features a different laser, processing technique or material.For the Chinese New Year an intricate dragon was cut out of stainless steel, for Easter a decorative egg was cut out of mild steel and to celebrate Independence Day, red and blue anodised aluminium was ablated to reveal the American flag. A Diwali message was percussion drilled in stainless steel with sparklers lit using a galvanometer scanning head, while Halloween was marked with a stainless steel pumpkin, ‘carved’ using a height sensing head.
Mark Greenwood, managing director of JK Lasers, said: “JK Lasers is a global company whose products are used in many industries for a wide range of applications. Our 2012 series of celebratory messages have been a fun yet highly effective way of demonstrating these capabilities to customers around the world.”
The video messages can be viewed on JK Lasers’ dedicated YouTube Channel www.youtube.com/jklasers. For more information about the company’s extensive range of fiber lasers, Nd:YAG lasers, process tools and software, visit www.jklasers.com, email sales@jklasers.com or call +44 (0)1788 517800.
* Maximum processing speeds will depend on the assist gas and motion system used as well as the profile to be cut.
