摘要： An apparatus and method for machining the surface of logs, in which the log is longitudinally advanced through an opening provided in a rotor disc and the surface of the log is machined by rotatable cutting heads mounted on respective supporting arms pivotably connected to the rotatable disc and rotating therewith around the logs. The cutting heads are rotated around respective axes of rotation, while concurrently the cutting heads rotate with the rotor disc around the log such that the net rotational speed of the cutting heads at the surface of the log is the sum of the speed of rotation produced by the rotatable disc and the speed of rotation of the cutting heads around their respective axes. In the course of machining the logs, the speed of rotation of the rotor disc is varied as a function of conditions at the surface of the log and the rotational speed of the cutting heads around their axes is varied in relation to the rotational speed of the rotor disc to maintain a substantially constant net rotational speed of the cutting heads at the surface of the log.
