Polygon Grinding

Process & Capabilities

This form of manufacturing was first developed by Fortunawerke of Stuttgart 45 years ago. We use 5 of their CNC grinding machines as they enable us to create customized parts that meet the exact requirements of our client’s projects. The workpiece is held in place on a rotating spindle positioned in front of a rotating wheel that smooths the surfaces down to a uniform and high-performance finish. Polygons provide extra strength, increased torque, and a longer product lifespan for applications requiring a high connectivity level.


At Stoffel Polygon Systems, our in-house grinding department can support your business with your latest prototyping and production projects. 

Our advanced polygon grinding machines offer unparalleled levels of precision when adding high-performance finishes to components. Our grinding team makes full use of our Surface & Cylindrical Grinders to deliver outstanding results on both short- and long-run polygon grinding jobs. 

Please get in touch with our team today if you don’t see the exact application you are looking for.

"We would like to thank the team at Stoffel Polygon Systems for completing our polygon adapter in an expedited manner. We are most appreciative of your focus and fine attention to detail. This has supported Goodrich in meeting the needs of our customers. The adapter has passed all inspections.

Michael O'Hara from Strategic Sourcing

"Kellogg Crankshaft recently received a very complimentary letter from Rotary Power International, Inc.'s Mr. W. B. (Bill) Silvestri regarding the specialized crankshafts for the Marine Corps. All of us in the industry recognize that praise is in limited supply today; our customers continually require more for less and faster. Kellogg would like to take this opportunity to recognize you, as our supplier, for providing quality, cost-effective services on this project. Rotary Power anticipates future opportunities, similar in nature, and will again be looking for a quality job and counting on all of us to offer suggestions to reduce costs wherever we can. Again, all of us at Kellogg Crankshaft thank you for your contribution to the success of Rotary Power International, Inc.'s five rotor crankshaft project. We look forward to continuing a mutually beneficial relationship with you on future work. "

Charles C Baker from Kellogg Crankshaft

"So nice to find a company so passionate about quality. Your shaft was (is?) beautiful. Perfect really. We, Conhagen, did not realize Stoffel would create shafts from scratch... In the future we will send you heat treated stock for your magic. We usually buy forged bars, annealed, quenched then tempered by our own heat treater. Normally, we run all 400 series stainless through a second temper after rough out as a stress relief operation to keep the shafts straight. "
