Figure 13-8: Grinding the radius
Grinding the radius:
The radius is created by swivelling the tool around the rotational axis. With the assistance
of the stopper A for the tilting movement, the position is to be set in which a continuous
rolling of the radius on the grinding wheel can be carried out. After every complete swivel
movement, in this case e. g. 110 degrees, infeed is carried out by means of the fine
adjustment and the grinding process is repeated.
Figure 13-9: Grinding the radius
Another method to grind the radius is to separate the rotary movement and the infeed.
Clamping is carried out in the initial swivel position and a larger material fraction is ground
off. After that, the material removal process is repeated with a new turning angle . This is
continued until the entire turning angle area is covered. After that the radius grinding is
finished in one go.
