Back rests are made to
support long slender work pieces on a cylindrical grinder. Some are fancier
than others, but all that we have seen consist of two "wear pads" on adjustable
arms such that they can be brought to bear against the work piece opposite
the grinding wheel and directly on the bottom. The material for these
wear pads can be bronze, teflon, delrin, babbit, or even wood.
Journal rests are usually much
heavier duty than back rests, and are used to support heavy rolls by
their journals while the roll surfaces are being reground. The range
of adjustment is usually quite limited, and sometimes it is necessary
to have several rests in different sizes ranges.
We do not at present have a
fill-in-the-blank data sheet for machine dimensions for back rests and
journal rests. Please inquire and we will discuss the information we
need to quote and the information we need to design and build.
