Process & Capabilities

Computer Numerical Control (CNC) milling is a precision machining process that can create complex and customized components. Using computerized controls and rotating multi-point cutting tools, material is progressively removed from the workpiece, making it ideal for prototyping and smaller production runs.


At Stoffel Polygon Systems, our CNC Milling Services have the capability of handling a wide range of materials and component specifications. Some of our capabilities include: 

  • Vertical milling: We have 3 HAAS CNC Vertical Mills
  • Horizontal milling: We have 1 HAAS CNC Horizontal Mill

Customer Stories

"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. This is a result of the fine level of workmanship we have received from Stoffel Polygon Systems. Thank you again for your teamwork on this project."

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. "
