The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque to output through the crankshaft and drive other accessories on the engine.
The crankshaft is subjected to the centrifugal force of the rotating mass, the periodic gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsion loads.
Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface needs to be wear-resistant, work evenly and have good balance.
An innovation of crankshaft grinding wheel, it finds its use in different automobile, truck, diesel, aircraft, and small engine manufacturing industries, and also in various engine modification companies for re-grinding pins and bearings.
Grinding and re-grinding of the main parts of the crankshaft, including
► Main bearing
► Rod neck/crankpin neck
► Flywheel flange end
Packages：Junker、Naxas、Landis、Schandt、Toyota、NTG Grinding machine.
Vitrified CBN grinding wheels are a significant way to prevent grinding burns on crankshaft shoulders. CBN crankshaft grinding wheels can be configured with various high-precision CNC crankshaft grinders, and are suitable for efficient and heavy-duty grinding of crankshaft pins and journals. The wheel speed is generally 80m/s-120m/s.
