Process & Capabilities

The CNC turning process is quick and provides a more affordable option than CNC milling

It starts by securing the material to a spindle inside the CNC turning lathe. Once secure, a cutting tool will remove undesired material until it reaches the shape and size of the finished component. Because of the speed, CNC turning is ideal if you need emergency replacements or urgent project deadlines. 


At Stoffel Polygon Systems, we have 5 CNC turning lathes that can produce the manufacturing parts you need for your latest projects. Some of our capabilities include: 

  • Facing
  • Threading
  • Knurling
  • Drilling
  • Boring
  • Reaming
  • Taper turning

Our team has the expertise to produce the parts you need, exactly when you need them. Please get in touch with us today to discuss your project requirements.

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. "
