Crankshaft grinding using the pendulum grinding method
JUNKER’s pendulum grinding method is a versatile machine concept for grinding crankshafts of all types. The JUCRANK machines use the pendulum grinding method to grind main bearings (cylindrical, concave, crowned,) pin bearings (cylindrical, concave, crowned) and thrust bearings in one or multiple clamping set-ups. Hardened radii can also be ground. Using straight, narrow grinding wheels allows for main and pin bearings of different widths to be ground with the same wheel. The grinding wheel can also be swiveled, allowing each bearing to be individually corrected for cylindricity.

Advantages of the JUNKER grinding method:
- Taper compensation / cylindricity compensation for each individual bearing
- Crowning can be freely selected
- Process order can be freely selected
- Longer grinding wheel service lives
- Rough and finish grinding can be done in a single operation
