The invention relates to a cutting machine, in particular a tread cutting machine, having at least one cutting blade ( ) linearly traversable on a blade carriage ( ) for achieving a feed movement and rotationally driven by a motor ( ), the motor ( ) for the drive of the cutting blade ( ) being arranged outside the blade carriage ( ), and a torque-transmission means, which comprises a means for transmitting tensile forces, being provided between the motor ( ) and the cutting blade ( ), and that part of the torque-transmission means which is traversable with the blade carriage ( ) having a markedly lower mass than the motor ( ). In this case, the motor ( ) is provided with a device which is designed as a closed-loop control or an open-loop control and is intended for keeping the rotational speed of the cutting blade ( ) at least approximately constant during a feed movement of the cutting blade ( ).
