Armstrong No. 51 Barnhart
Band Wheel Grinder
Barnhart grinder is a very effective, popular tool for grinding the faces of band
wheels. Equipped with ball bearings in the arbor, the No. 51 Barnhart grinder is
designed to grind band wheels running at full speed.
The optional motorized head attachment, or
power head, provides increased safety to the operator by eliminating the need for a steel
belt or "blank" saw to drive the top band wheel. The power head is easy to
set-up and is completely interchangeable with the standard head on both the No. 51 and No.
The portable Barnhart Grinder is easily
installed and mounts directly on the band mill. The 4-screw end brackets, as shown
in the photo, are quick and simple to adjust. Once in place, the Barnhart can be
used to grind band wheels flat, with a "step crown" or with a slightly arched

BARNHART GRINDERS FEATURE:
The No. 51 Barnhart Grinder is designed to
work fast and accurate with band wheels running at full speed and in place. The
2" wide zirconium resinoid wheel quickly cuts both cast iron and steel wheels.
The Barnhart grinds band wheels with absolute
accuracy and provides a far superior finish than "tooled" wheels. The
precise grinding angle is determined at the factory and requires no adjustment.
The Barnhart mounts directly on the band mill
and uses 4-screw end brackets for quick and simple adjustment.

a steel belt or "blank" saw to drive the top wheel, making the job quicker and
With no saw or steel belt required, time
consuming set-ups are eliminated, especially on Quad, Twin and Single band wheels with
limited space between the wheels.
The power head is easily installed on both
the No. 51 and 51-L Barnhart Grinders, using the same holes as the standard head.
Safety guards are provided covering the belt, pulleys and grinding wheel.
The easily attached remote control unit
allows the operator to accurately control the movements of the grinding wheel while
standing back away from it. An excellent safety feature, the remote control option
reduces the hazard of flying grit without sacrificing accuracy.
