Solved: Simple Ball Milling Filleted Edges Not Starting Or

the starting cut leaves a ridge i suppose because the max stepdown is set to .006 so the first pass does the max stepdown. the real issue is the tip of the ball mill will not go lower than the bottom of the .125 radius. my calculations put the last pass at .1875+.125.... which is z-.3125. no matter what i do i cannot get it to go below z-.125.,influence of high-energy ball milling of the starting,two different methods of dry milling and wet milling in a liquid alcohol medium were investigated along with three ball milling times (1,2 and 3 h), two different types of starting powders, and three different sintering temperatures (1000, 1050 and 1100 degrees c). xrd, sem and oxygen permeation measurements were performed on as-prepared membranes.

ball mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. the comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding,ball mills - mine engineer.com,if the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. the point where the mill becomes a centrifuge is called the 'critical speed', and ball mills usually operate at 65% to 75% of the critical speed.
