Our high-efficiency manufacturing techniques significantly reduce production costs and result in tough, durable crankshaft parts.
A single hot forging machine performs all the work processes—including cutting, de-burring and drilling—to produce a complete forged crankshaft piece. Also, Yamaha has developed a die cooling process to shorten cycle time, reduce the amount of release agent used and more, all leading to lower costs.
Carburizing and quenching is used to increase surface hardness, and improve bending fatigue strength, surface fatigue strength and wear resistance. This makes for high-performing, longer-lasting products.
