Winona Van Norman CPX80 Crankshaft Polisher

  • Model: CPX80
  • New Machine; Call for Pricing

The Winona Van Norman CPX80 is a professional-grade crankshaft polisher designed to produce smooth, consistent journal finishes on both automotive and diesel crankshafts. Built on Winona’s well-known heavy-duty polishing platform, the CPX80 allows operators to quickly refine journal surfaces after grinding, improve RA finish quality, and prepare crankshafts for assembly or performance use.

 

With adjustable work supports, a variable-speed drive, and a rigid frame that keeps the crankshaft steady during polishing, the CPX80 delivers uniform crosshatch and journal geometry every time. Its simplicity, durability, and reliability make it a staple in automotive machine shops, production engine-remanufacturing facilities, and diesel rebuild centers.

Built on Real Engine-Rebuilding Experience

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.

A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.

Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
