Machines power engine building
High-performance motorcycle-engine builder R&R Cycle in Manchester, N.H., differentiates its product by being the only manufacturer in the country producing full-billet engines. While these engines result in superior performance as compared to those made from pre-formed castings, they do require more machining at tight tolerances, which R&R accomplishes on two NH5000 Mori Seiki machining centers.

These rigid machines let the shop hold tolerances to within 0.0005 in., unlike its previous machining centers. They rested on individual feet, and as temperatures changed with the seasons, the shop's shifting concrete floor caused part inaccuracies.
