CNC contour diamond roll dressing.
CNC contour diamond roll dressing is the one
way that thread grinding can be fully automated. A precision diamond
roll can be used to create the exact thread-form profile on the
abrasive wheel, using a continuous path movement and holding tolerances
in the tens of millionths. Automatic dressing assures that the wheel
is properly shaped and sharpened at all times. Frequency of dressing
depends on such factors as the surface finish needed, wheel type
and removal rate.
