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.

Objective Produce an increase in the number of ground journals per dress with a surface roughness of  ≤ 1,0 µm
