Mittler Bros. Machine & Tool, a respected supplier of premium fabrication tools and racing components, is pleased to announce that it now offers steel billet crankshafts for racing and specialty applications. Mittler Bros. acquired the crankshaft segment of Grand Rapids, MI based Oliver Racing Parts. Cranks are produced for many diverse markets including oval track racing, road racing, vintage road racing, off-road racing, drag racing, tractor pulling, and antique restorations.
Mittler’s billet cranks start with high density steel forging billets.
Cranks are rough-to-final formed on a 5-axis CNC lathe.
The Mittler engineers develop a solid computer model from a customer order and then create the final crankshaft from the model. The dynamics of the complete rotating assembly are analyzed via FEA (Finite Element Analysis) and other sophisticated computer programs. Each MB crank features subtle differences in the size, shape and positioning of the counter weights and crank pin design. This design provides efficient mass/radius counter-weight design allowing for minimum weight counter balance. It also produces a maximum strength crankpin with minimum weight by sculpting and shaping the crank pin to produce the highest strength at the lightest weight. An efficient aero design is applied to the leading and trailing edges of the counter-weight to minimize parasitic losses
MB billet crankshafts are manufactured with a unique CNC machining process for maximum flexibility in manufacturing which allows for efficient customization of strokes and counter weight design. All MB cranks use the highest quality 4340 billet steel. The crankshafts receive a triple heat-treat process including ion nitriding, providing maximum strength and life.
