Abstract
Described is a laser processing machine with a height-adjustable laser component, a height-adjustable machine component, and a weight compensation system. The weight compensation system has at least one roller unit that includes at least two rollers fastened on a common axle and rotatably fixed with respect to one another. The axle is configured to rotate freely and slide in a machine frame guide of the laser processing machine. The laser component is held suspended by a first traction member wound onto the first roller. The machine component is held suspended by a second traction member wound onto the second roller. The first traction member and the second traction member are wound in reverse (opposite) directions onto the rollers. A counterweight device acts on the axle by exerting a counterforce, which compensates, at least partially, for the forces exerted by the laser component and the machine component.
