The Wimmer saw head impresses with the following features. It is placed at an angle, which results in a softer first cut and cutting and a higher cutting performance. We first delivered the angled Wimmer saw head in 1996. The saw blade runs on cast steel wheels with 850 mm or 1000 mm diameter, which are stored in duplicate in the large size with cylindrical roller bearings. Compared to cast iron, cast steel is characterised by a much longer service life. The solid square or rectangular pipes of the saw blade tensioning system are precisely guided on a total of 16 brass plates with a long support spacing. It is also possible with weaker logs to saw with less pressure without the saw blade drifting, which leads to a further increase of the service life of the saw blade.
