Scoring unit
The scoring unit is an aid for processing panel material with a plastic coating with circular saws .

The saw blade of a table saw rotates so that the cutting teeth work towards the table, so that the workpiece is pressed against it. Otherwise the workpiece could be thrown away. However, this direction of rotation of the saw blade means that the underside of the workpiece can tear out. Whether and how strong the tear is depends on many factors. Among other things, on the type of wood, the sharpness and geometry of the saw blade and a few more. Above all, the plastic-coated panels mentioned at the beginning have a very strong tendency to tear. To prevent this, scoring units are available for many sliding table saws . This houses another saw blade, mostly smaller in diameter (approx. 100 mm), but a few 1/10 mm wider than that of the main unit, which is exactly in line with the main saw blade but in the cutting path. This is clamped in the opposite direction to the main saw blade so that the teeth point upwards. The scoring saw blade scores the piece of material a few millimeters deep before it reaches the actual saw blade, thus preventing tears and deviations.
