Successful application of WinterTech CBN grinding wheel in engine crankshaft machining

Abstract The crankshaft is the most important component of the engine. It converts the force of the up and down movement of the piston from the connecting rod into a torque output and drives other components on the engine.

The crankshaft is the most important component of the engine, transforming the force of the up and down movement of the piston from the connecting rod into a torque output and driving other components on the engine. The crankshaft is subjected to the centrifugal force of the rotating mass, the cyclically varying gas inertial force and the reciprocating inertial force, and is subjected to the bending torsion load, so that there must be sufficient strength and rigidity. The surface of the journal needs to be wear-resistant, uniform, and balanced. Correspondingly, the requirements for the roundness, roughness, straightness and unevenness of the journal surface are also high.
