At Stevens Rowsell we operate a fully automated Trumpf 4kw Trulaser with two 8m tall material storage towers and an integrated sheet handling system for automated loading and unloading of sheets 3000 x 1500mm.

Benefits of using Laser cutting technology

Our technologically advanced Trumpf Laser Machines provide us with an efficient, high speed and cost effective form of profiling sheet metal which ensures that the work we produce is competitively priced, is turned round quickly and has a superior clean cut and oxide free finish. The features and benefits to our customers are thus:-

dot spacer High speed cutting with Nitrogen - gives clean edges, no oxide and limited discolouration and therefore a more visually aesthetic finish
spacer
dot spacer Auto Height Sensing - No material marking
spacer
dot spacer Positioning and dimension accuracy of 0.05mm guaranteed
spacer
dot spacer Oil on Pierce - (Anti Splatter) for cleaner dross free cut
spacer
dot spacer Laser Cat Eye – Allows the use of pre-punched / formed blanks
spacer
dot spacer Parts can be marked for identification purposes
spacer
dot spacer Advanced Process Control (APC) - Guarantees process reliability in piercing and cutting by automatically determining the exact sheet position on the laser bed and thus regulating the distance between the cutting nozzle and the work piece. This helps to produce a better cutting result regardless of the sheets unevenness and also eliminates the need to manually reposition the sheet thus preventing scratches to the underside of the work piece.
spacer
dot spacer Latest generation software - Automatically nests different part profiles from different jobs on the same sheet which helps us to maximise sheet utilisation & reduce wasted material as well as cutting more than one specific job at the same time. This software coupled with the laser technology we employ helps us offer highly competitive pricing and a genuine value for money metal cutting option.
spacer
dot spacer Intelligent planning - the software also reports back to our business system helping keep our production scheduling accurate and our delivery dates on time.
spacer
dot spacer Versatility - The laser beam is effectively a multifunctional tool  which can cut through a wide variety of materials (including coated sheet), whether thick or thin. Part geometry (size & shape) can be simple or highly complex enabling the laser to cut an infinite range of shapes and forms.
spacer
dot spacer We can produce one off prototypes or provide a quick turn around on production quantities.
spacer
dot spacer Customised automation - We have a fully automated laser cell incorporating two 8m tall sheet metal storage towers with 50 individual storage stations and an automatic sheet changer. The system fully automates the loading and unloading operations transporting raw material sheet to the bed of the laser (by means of suction cups).  An unloading rake then transports the finished work pieces and scrap skeletons from the machine to the finished parts stack whilst a new sheet is conveyed to the bed of the laser to continue the cutting cycle. The loading device enables seamless and constant handling even when heavy sheets are involved, doing away with the need for men and cranes to perform the operation. Material loading, production and parts unloading therefore all take place simultaneously, eliminating downtime, increasing capacity and reducing delivery lead times.

These CO2 gas lasers operate according to the "flying optics" principle, whereby the laser beam is moved over the working area whilst the work piece remains static. This allows high processing speeds and very high quality cutting to be achieved independent of material weight.

spacer Making light work of a precise cut through steel
How is our laser beam produced?

A turbine prepares the laser gas (a mixture of carbon dioxide, nitrogen and helium) at a specific ratio and delivers the mixture to a discharge tube at high speed and under pressure. Inside the discharge tube there are electrodes which stimulate the mixture between 2 mirrors (called a resonator) to produce a laser beam. The output mirror allows a certain percentage of the beam to leave the resonator. The beam is then focussed onto a convex lens in the flying optic. The resultant laser beam has an output range of up to 3kw and the ability to cut through a wide variety of materials including;
