Development of Environmentally Friendly Fluid for CBN
For the grinding test the selected tool was a vitrified CBN wheel, B181 concentration 125, dressed with a diamond disc. The conditions were: grinding speed v s = 33 m/s, workpiece speed v w= 660 mm/min, grinding width b = 6.5 mm, grinding wheel penetration/pass a = 25µm. Dressing depth of cut a d = 10 µm, dressing overlapping ratio U d= 4.
