Characteristics on unpolished rings:
If the ring between the rolls does not turn, the rolls are
unpolished to the half in each case ! (the use of both matt
halves make a subsequently polish necessary !)
The rolls are unpolished transverse to the working direction approx
in each case. For test purposes please use an old silver ring and pay
attention on the fact that the matt surface affect the ring.
The matt finish cause a better transport of the ring
(we use this variant in our workshop, too ! )
By the conical process and the different material thickness of the
ring there is a little intuitive feeling necessarly.
Work without the lock screw first and exert only light pressure with
the hand. Naturally you can also change the position of the ring between
the rolls.
More easy pressure and frequent turning back and forth leads to the
best result. The practice-ring should now be matt, but clearly larger.
Now exchange the unpolished upper Profilroll against a smooth one and
make sure that the inside of the ring affects the unpolished surface
of the lower rolls.
