Ratio Machining specializes in manufacturing Mandrels for the Cold Pilgering Industry. Established in 1981 by Georges Rouleau, the company has evolved to offer a range of services, including creating inspection machines with proprietary software, retrofitting manual lathes and grinders with CNC capability, and developing steady follow rests for mandrels of various diameters. Following Georges' passing in 2008, Ratio Machining continued its success under new ownership, investing in new equipment to enhance mandrel production speed while maintaining precision. With over 20 years of machining experience, Ratio Machining now provides best-in-class Mandrels as well as one-offs, short-run prototyping, and production runs for various industries.
