  • Publication number: 20210394289
    Abstract: A method for predicting the remaining service life of a saw band in a bandsaw machine, in which a behavior or properties of the saw band clamped in the sawing machine are monitored by at least one sensor during operation of the sawing machine. Changes in the behavior or in properties of the saw band over time established on the basis of measurement signals of the sensor device are used for making a prediction about the time at which a band will break. The behavior or properties of the saw band are indirectly monitored using the at least one sensor device by way of detecting changes to components of the sawing machine which are operatively connected to the saw band.

    Abstract: A band saw machine for sawing metallic workpieces, having a lower saw part and an upper saw part with two carrying wheels mounted therein, and a saw band that revolves with a cutting motion around the wheels that passes through a cutting region. A feeding device attached to the lower saw part feeds workpieces to the cutting region and/or into a sawing plane, in which the cutting region of the saw band is moved in a saw advance motion. The feeding device has a movable holder for detachably fastening the workpiece, and the holder, starting from an initial position, is movable both with translational and rotational motions. The saw band is guided through the cutting region, and the holder is moved translationally against the cutting region in order to execute the saw advance motion. Here, the workpiece is preferably turned by the holder such that its upper side faces downward.

  • Patent number: 10596645
    Abstract: A method for controlling a sawing machine is provided. For a first cut in a workpiece, a working feed rate that is specific to the workpiece geometry, the workpiece material and the sawing tool is defined in advance. During the first cut, an instantaneous value of a physical variable is determined at a frequency converter, that is related to the torque transmitted by the sawing tool drive to the sawing tool, and this value is transmitted as an instantaneous torque value to a machine controller. The instantaneous torque value is continuously evaluated, a maximum torque value of the first cut is determined and a maximum value for the torque value is defined based thereon. For subsequent cuts in the same workpiece, the working feed rate is regulated, using the instantaneous torque value as a regulating variable, such that the instantaneous torque value is kept constant, close to the maximum valve.
