The axes of your machines and laser systems are covered with bellows to protect the sensitive beam guiding optics of your laser against dust and other particles. Only purified air or nitrogen is permitted inside the bellows, so that the laser beam is not absorbed or deflected. Due to the material quality, original bellows guarantee the best protection of the beam path, also ensuring the focal positioning on the workpiece. The bellows are subjected to extreme mechanical loads due to the high speeds of the cutting head and the entire motion unit, as well as the resulting pressure changes. This is why original bellows are made from particularly flexible, but also very stable and self-extinguishing plastic. Even in 3-shift operation, this means you can count on the long service life of your original bellows for the long term.
