Dynamic Metals commissions 8kW Fiber Laser
In February 2019 specialist subcontract metalwork supplier Dynamic Metals, LLC commissioned a brand-new Mitsubishi Electric ML3015 eX-F80 8 kilowatt fiber laser profiling machine at its factory in Elkhart, Indiana, USA.
The new fiber laser began its career at Dynamic profiling components from heavy gauge armour plate for the defence sector and thick aluminium for the transportation sector. This investment is Dynamic Metal's second collaboration with Mitsubishi Electric, with its first being a 4kW fiber machine in late 2016. The 4kW machine was highly successful and noted for its cutting performance and low maintenance requirements and it now has a home at Dynamic's sister company - Gem City Metal Technologies, LLC in Dayton, Ohio - which then made room for the new 8kW at Dynamic.
Dynamic Metals also runs an Amada F0-MII 3015 4kW CO2 laser in its laser department where the production of heavy gauge metal profiles is common. This emphasis on thicker materials made the decision to invest in the higher-powered laser straight forward thanks to the increased productivity provided by the extra power. The machine is coupled to an automated material handling system complete with two loading and two unloading carts to maximise the machine's cutting time.
Referring to the developments at its sister company, Hydram’s Managing Director David Greatorex said, “I’m delighted to see continued investment in the latest technology amongst the Dynamic Group. It shows our commitment to providing highly capable, productive processes that keep control of costs for our customers.”
Mitsubishi Fiber Laser
Thin sheet metal can be cut particularly quickly with fiber lasers as the short wavelength of 1.07µm provides extremely high power density in the cutting zone and thus achieves outstanding efficiency. In short, the energy input into the metal is higher compared to that with CO2 lasers and so the cutting speed is faster.
High-performance fiber lasers have a modular design where the source is made up of multiple fiber modules. Each module has a number of laser diodes which “pump” the “active fiber” and generate a laser beam. These laser modules are grouped together and the combined laser beam is then guided via a flexible fiber optic cable from the laser source to the processing head of the laser cutting system.
A notable feature of the Mitsubishi laser is the Zoom Head. This allows rapid adjustment of the beam properties to provide the optimum cutting conditions and quality so that changeovers between different thicknesses of sheet material are seamless. The optics in Zoom Head are hermetically sealed to protect them from contamination during the rigours of everyday operation so that the maintenance requirement is minimised.
