We can return your machine to "like-new" condition. We have in our archives the original documentation for most Bourn & Koch machine brand models. Our facility was built to facilitate a timely and efficient machine tool rebuilding process in order to minimize the downtime of your machine.

• Rescrape/Realign - Realign existing machine geomety
• Rebuild - Restore machine to "like-new" OEM condition
• Remanufacture - Upgrades a manual machine by adding a CNC control, updating the electrical and mechanical components, and performing a complete machine rebuild. It is equivalent to a current design machine having all the parts replaced, remanufactured or determined acceptable to machines tolerances and performance.
• Retrofit - Enhance machine with PLC and CNC technology upgrade

Rebuilding:
The purpose of a rebuild is be bring the machine back to an as new condition with the same level of control and electrics. This involves restoring a machine its "as good as when it was new" condition by replacing all bearing and seals and inspection of all components. Major defective parts are reviewed with the customer and replaced at additional cost to restore the machine to its original mechanical specifications and operating condition. The electrical components on the machine and the electrical panel are inspected and replaced as necessary.

Remanufacturing:
This process involves taking a "manual" machine, adding a CNC control and updating the electrical components, as well as performing a complete machine rebuild from the base up. This machine typically does not currently have or never has had a modern CNC control on it.

Retrofitting:
This involves installing or replacing the existing NC or CNC control and, if necessary, servo drives and motors on machines that currently have servo axis drives. This machine currently has as NC or CNC control. This scope does not include mechanical rebuild.

Give New Life To Your Old Fellows 36-6 Gear Shapers

Double your productivity with Bourn & Koch's Remanufactured Fellows 36-6 Gear Shapers

Bourn & Koch's remanufacture program for old Fellows 36-6 Gear Shapers gives new life and productivity to a large gear shaping machine whose original design dates back to the 1950's.  Bourn & Koch's Fellows remanufacture team strips your old machine down to the castings and starts over again, eliminating change gears, the speed gear transmission mechanism, the feed gear set, and replaces them with servo drives controlled by CNC.  Optionally, the worktable wormgear can (or needs) be recut, the worktable assembly and table relief system can be locked and replaced with Bourn & Koch's unique cutter relief system (patent pending) and a quick return stroke servo drive for the cutter stroking.

The CNC allows programming the gear and cutter data and setting the feeds and speeds, allowing a change in cutting feeds and speeds on the second cut - something you could not do automatically on the old design.

Some users have had their machines remanufactured with large, throated subrisers to allow a greater swing diameter for large, tall workpieces.

In a current market where there is a scarcity of large used or rebuilt gear shapers, remanufacturing your old Fellows makes sense.  Tell us the serial number of your Fellows 36-6, 36-8, 36Z-6, 36-12 or 48-8 and we'll send you a quotation.  Request a quote from sales@star-su.com.
