"Trumpf provide TruFiber model that can achieve a typical focus diameter of 10 to 50 µm. The resulting high power density at the work piece translates to high processing speeds. That s the key to high productivity. During precision cutting, the optional Cutassist module supports the user. It fits the laser parameters to the cutting speed completely automatically, giving the best cut quality and maximum productivity. The laser power is controlled in real-time and with the built-in frequency generator it can be modulated with up to 50 kHz (TruFiber 500) and up to 10 kHz (TruFiber 1000)"
