- Royal Master Grinders, Inc. literature:

"The machine's design is based on our
standard grinder line with some very
notable exceptions. The machine
bed has been enlarged to add to the
stability of the system, and accommodate
the new ram swiveling feature.
The ram now swivels on a pivot under
the ram, moving the entire lower ram
and dresser assembly together.

This is an advantage during thrufeed
grinding that the guides do not have to be
readjusted when you swivel. Also the swivel
is gauged by a digital indicator, and
the adjustment is made by a easily
accessed handle. We have also added a
servo drive regulating wheel system.

The electrical system is easily accessed
by way of a JIC electrical enclosure
mounted in a space saving position
over the coolant tank. The accuracy
of the system was tested on customer
applications, and the results were
impressive. We were able to achieve
roundness to less than .000010", and
straightness to less than .000010".
We are able to make size compensations
with this system in 0.000010" as well.
The positioning system consists of
a servo driven ball screw unit and
the system's movements are verified with
a glass scale with .000004" resolution."
