Opening width mm

Similarly to the opening height we understand the opening width to be the maximum width of the workpiece, whereby it can be fed through the machine in an unprocessed condition together with its processing units. Depending on the machine type, the opening width is limited by various design features.

Band saws

With band saws without mechanically powered feed rollers on the machine table, we define the opening width as the distance between the machine frame or the stop located here and the saw blade. No stop is located beyond the saw blade, as can be seen in the top right illustration. This type of band saw therefore has no opening width restriction. In the case of band saws with powered feed rollers, i.e. resaws, the opening width is limited by the feed rollers on the left and right of the saw band.

Multiblade saws, double edging saws, double spindle ripsaws

  • With multiblade saws and double spindle resaw only relevant with enclosed designs. We cite the maximum distance between the fixed machine frame and the machine housing here in mm.
  • With double edging saws this is the distance between the shaft bearings located on each side.
  • This equates to the maximum width of the workpiece, whereby it is able to feed through the machine in an unprocessed condition.
