Fibre lasers achieve a high level of absorption in metallic materials, they have an electrical-optical efficiency of approx. 30% and offer outstanding beam quality. These characteristics allow the cutting of metal alloys from steel, aluminium and copper.
The granite bodies of the longitudinal axes rest on steel construction that was annealed to eliminate stresses. The large mass of the granite axes and the specific properties of the granite, such as long-term stability, vibration damping and low-temperature expansion, form a solid and highly precise basis for dynamically moving parts of the machine.
Achieving the shortest possible production time for the manufacturing of complex, delicate parts requires the highest level of dynamics which is achieved through a reduction of the moving masses. On the STIEFELMAYER effective S, this was implemented by using lightweight carbon constructions for the moving Y-axis and its attachment parts.
No drive technology other than linear motors is better suited for achieving the required dynamics and precision. It generates a direct, straight movement, allowing vibration-free transmission of forces into the moving parts of the machine. This enables the highest level of path accuracy with the highest level of dynamics. In addition to this, linear motors are mostly free from wear.
