Ball Mill Loading - Dry Milling - Paul O. Abbe

50% media charge Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading. So as a rule of thumb we use 25% solid loading.

Ball End Mills - Haas Automation

HTPM series milling cutters have unequal flute spacing (variable pitch) and multiple helix angles (35° and 37°) to reduce chatter and harmonics, for improved stability and better finishing. This also optimizes chip formation and chip evacuation. These 4-flute end mills feature a spherical ball end. Aluminum Chromium Nitride (Hybrid AlCrN) coating reduces wear and increases heat resistance.
