Machinery Service & Design, Inc., uses a “G & P 72” Abrasive belt polisher Model B372-3 as its polishing head. The head uses a 3” X 72” belt and is driven by a 3hp. 230/460 volt, 3 phase, 60 hz. motor.

A 5 HP head with a 3” x 90” belt is available to increase the time between belt changes. A larger horsepower head with a longer belt is available to increase productivity and increase the time between belt changes.

The polishing head is driven horizontally the length of the fixture by a vector A.C. drive. A rack and pinion drive system is used for smooth traversing of the carriage. The head is supported by four Teflon lined guides, which slide on aluminum support rails.

A remote jog can be added to speed up set time or to manually polish and area.

As an option, we can offer these in a buffing wheel only or buffing wheel & belt combination.

• No need for centering or chucking rod in lathe. Faster setup time.
• Clevis can be hung over end of fixture. Less setup required.
• High micro-finish.
• Can be used to check concentricity of shafts.
• The belt polisher can be positioned for specialty processes, i.e. angle grinding and chamfers.

Head can be tilted to grind chamfers or angled surfaces.

Clevis can be hung over end of machine for faster, easier setup. No machining required.

Levels repair welds on shafts. Head slides in and out to position wheel over rod for removing high spots.

Gear motor drives one set of rollers.

Drive rollers – Idler rollers – Chain guard.

AC motor – Rack and pinion drive.

Teflon-lined guides and aluminum support rails.

Electrical Package

The electrical package will allow automatic reversing of polishing head with time delays at the end of strokes. This feature can be used to remove chrome build-ups on re-plated shafts. The magnet stops can be easily placed to reverse the polishing head at the end of the rod being polished.

Stroke position limit switch and magnetic stop for stroke positioning.
