A two-axis cutting machine for cutting a workpiece along a desired cutting path, has a frame for holding the workpiece, a rail fixed to the frame, a beam arranged to move along the rail and having a pair of driving points spaced apart along the axis of the beam, a cutting tool arranged to move along an axis of the beam, an elongated flexible drive means having portions engaged respectively at the two driving points, a carrier mechanism for carrying a drive section of the drive means, and for translating a force applied on the drive section into a pair of resulting forces directed parallel to the rail and applied respectively at the two driving points, and a beam drive motor mounted on the beam for exerting a force on the drive member, whereby the resulting forces move the beam along the rail, while maintaining a constant angle between the beam axis and the rail.
