Typical Cross-Slide Attachment Thread
Roll Applications
C1
These
rolls with standard hubs, are
generally used for rolling on
the outboard end of the work
as shown, or where the standard
working face of the roll is
satisfactory for the length
of thread to be rolled, and
the position of the attachment
relative to the collet face
is unimportant. All other types
of rolls are modifications of
this design. |
C2
These
rolls, with a narrow working
face, are generally used for
rolling the thread at the cut-off
end behind a shoulder. With
the working face at the plain
hub end, it permits positioning
the cut-off end of work close
to the collet face. |
CR-1
When
thread lengths permits, reversible
rolls of this design can be
used and provide for two setting
of the roll. The design includes
two standard drive hubs for
ease of assembly in the head.
The rolls can be reversed without
repositioning the attachment
or other cross-slide tooling.

K-2
These
rolls are designed for rolling
taper pipe threads when the
small end of the taper on the
work is towards the collet.
The length of working face is
determined by the requirements
of the work. |
Q2
These
rolls are designed for rolling
taper pipe threads when the
large end of the taper on the
work is towards the collet.
The length of working face is
determined by the requirements
of the work. |
DR-1
These
are reversible rolls designed
with an extended working face
and recessed drive slots at
both ends for two-roll settings.
They are a modification of a
type of CR-1 roll, providing
additional thread length capacity.
The rolls can be reversed without
repositioning the attachment
or other cross-slide tooling. |
Other
thread roll applications include:
C-3, C-4, C-5, CR-4, CR-5, D-1, D-3,
