What is Profile Creep Feed Grinding and how does it work?
Since many profile grinding tasks in series production are performed in creep feed grinding, e.g. grinding of turbine blades, CD grinding (continuous dressing) is the most economical solution. The wear of the grinding wheels is immense, but due to the always sharp abrasive grain, higher infeeds and feed rates can be selected.
