Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

I'm using a 5/32" 4 flute ball nose end mill, moving in the z direction at 0.15mm each step and have a cut feed of 150mm per minute. The cutter was brand new so I don't think that was the problem. I first rough the path with a 5/32" square end mill and I leave 0.25mm material for the ball nose operation.
