when you finish making the pipe holder parallel to the contact disc you fasten the two nuts
that the arrow points to again.
Height adjustment of pipe holder to the middle of the roll holder is done through a similar
adjustment of the 4 screws mentioned above. Now you have to turn all 4 nuts at once. One
full turn equals a 1 mm
(0,04”) adjustment.
3.6 Angle of Pipe Notching
The grip (pos. 41 on the spare part list of the aggregate) is loosened and rotated to the
desired degree, after which it is tightened, and the subject is placed in the vice and
fastened.
Fig. 3.6 shows a pipe and sanding belt from above. A RB pipe grinder can grind at a
maximum angle
of 0 . The width of the band, however, limit the scope. An RB75 is limited
for pipe sizes over 35 mm
/1.4”, while an RB150 is limited for pipe sizes over 72 mm/ 2.8”.
You can interpolate in according to the table in Fig. 3.6.
