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. |

1. A laser processing machine comprising:
a machine frame guide; a height-adjustable laser component; a height-adjustable machine component; and a weight compensation system comprising at least one roller unit, first and second traction members, and a counterweight device; wherein each roller unit comprises a first roller and a second roller fastened on a common axle and rotatably fixed with respect to one another, wherein the common axle is positioned and configured to rotate and slide freely in the machine frame guide, wherein the height-adjustable laser component is held suspended by the first traction member wound onto the first roller, wherein the height-adjustable machine component is held suspended by the second traction member wound onto the second roller, wherein in each roller unit the first traction member and the second traction member are wound in reverse directions onto the first roller and the second roller with respect to one another, and wherein the counterweight device is configured to act on the common axle of each roller unit by exerting a counterforce on the common axle, wherein the counterforce compensates, at least partially, forces exerted respectively by the height-adjustable laser component and the height-adjustable machine component on the common axle in a sliding direction in the machine frame guide. |
