Plunge grinding of journals

WINTER: Innovation - Precision - Performance - Quality

When in use camshafts are subjected to up to 10⁹ of torque and therefore have to be extremely strong and resistant to fatigue.

In order to be effective, camshafts must comply to certain quality requirements, including surface finish, cylindricity, straightness and concentricity.

This is only achieved by grinding with vitrified cBN wheels.
