For indicative settings of the draft size and the actual machining process, you can use the
tables for settings of various bevel angles.
Important:
The values in the table are calculated from the so-called 0 point. The 0 point is the
point, when the cutter touches the material edge for the first time. The point can
be set by gradual turning of the pressure disc (fig. 10.0.1, position E) and attaching
to the material edge.
45° - For full bevel (P = 15 mm), the pressure disc must be turned by 5.2 revolutions.
