Hobbing system CNC or Pfauter system In the hobbing system (or Pfauter system) a screw-shaped tool is used, which once directed and rotated, creates the type of toothing required by the design. In addition to the classic hobbing, GSI can also work using the most innovative Skiving technique, which allows you to finish the tooth profile. In this case, a hard metal hob suitable for the size of the toothing is used, or as a replacement for a grinding wheel when the area to be machined is too small. Shaper Cutter Toothing or Fellows system In the Shaper Cutter Toothing (or Fellows system) the tool is circular and has the characteristics of a wheel. It has two different motions: the uniform rotary motion for the advancement and the alternating rectilinear motion for cutting. It is used both for the external dentition, but much more often for the internal dentition. Tooth size: Diameter 300 mm, Module 6
