With a cylinder saw arranged rotatably in a machine frame, only circular profiles are sawed out of boards and beams. This cylinder saw possesses a toothed arrangement, at least on the front side, and is rotatably supported by support and guide rollers in the machine frame. The outside circumference of the cylinder saw is embraced by a continuous, driven belt. A planing fixture is arranged behind the device for sawing out circular profiles with the aid of the cylinder saw and with this planing fixture any desired concave, convex or straight profile shapes can be milled into circular wooden pieces or boards. The planing fixture consists of four profile planing shafts arranged uniformly distributed on the outer circumference, the axes of which are adjustable relative to the longitudinal central axis of the wooden beam to be processed.
