STARTLING EFFECT OF BALL SCATS REMOVAL ON SAG MILL .An increase of over 10% in mill throughput was achieved by removing the ball scats from a singlestage SAG mill. These scats are nonspherical ball fragments resulting from uneven wear of balls with included porosity. 30t of scats were removed from a total charge load of 70t. Surveying and modelling the mill revealed that the breakage rates

How to flute a rifle barrel – Using a ballnosed endmill comes at the price of decreased speed and depth of cut. On a vertical milling machine, the ballnosed endmill will mean that the cut has to be made from the top down. This will require the barrel to have additional support underneath. A 3/16″ PTG fluting cutter (left) and solid carbide ballnosed endmill (right).

How to solve this with a ball mill? Autodesk CommunityHi! I try to use a ball mill to make the slot shown in the picture. I would just do a 2D contour. you would most likely need to set the depth manually bit the rest would be easy. draw a line at the bottom of the slot and then 2d contour turning compensation off, of course make the line longer than the slot.
