What are the Manufacturing Processes for Engine Crankshafts?

The manufacturing processes for engine crankshafts are diverse, encompassing forging, turning, grinding, drilling, milling, quenching, tempering, and more.

Forging provides the crankshaft with high strength and good toughness, enhancing its load-bearing capacity. Turning and grinding ensure dimensional accuracy and surface quality of the outer diameter and journals. Drilling and milling are used to machine specific areas. Quenching increases surface hardness, and tempering eliminates internal stresses from quenching.

These processes each have their purpose and together ensure the high-quality production of engine crankshafts, enabling them to function stably and reliably in engines.
