Definitions

  • the invention relates to a scoring tool for a circular saw machine, especially for a sliding table saw after the Preamble of claim 1 and a scoring saw blade therefor.
  • Such a scribing tool is used in particular used when using a circular saw blade Material with a sensitive or brittle top layer to be cut. With the separating cut, the Saw teeth of the circular saw blade under a relatively flat one Angle emerge from the workpiece surface layer, whereby on Leaf runout on the top layer flaking or tearing occur.
  • Known scribing tools used on sliding table saws consist of two sub-sheets and arranged in between Spacer rings, with the partial blades the scoring saw blade form and between two flanges on a drive shaft are excited. Adjusting the cutting width of the Scoring tool to the current cutting width of the circular saw blade is done by removing or adding an or several spacer rings. In practice, the Cutting width of the re-sharpened circular saw blade measured; then the scoring tool is removed from the drive shaft taken, dismantled and a necessary number of Spacer rings arranged. The part sheets of the scoring tool are then again axially fixed on the Drive shaft mounted.
