The crankshaft has a complex shape with multiple cranks, and the crankshaft pin and main journal are not on the same axis; Multiple cranks form an imbalance of 120 ° in space.
The crankshaft has a slender shaft with a rigidity difference, and a length to diameter ratio (L/D) of 10-20. It adopts a center frame and transmits torque to the machine tool on both sides simultaneously.
High technical requirements for parallelism: Use the main journal as the benchmark to process the crank pin. The radial circular runout of the main journal should be processed in the same installation.
