To produce radii this large with a traditional ball nose end mill, the ball nose cutting tool would need to be up to 3,000 millimeters in diameter or even larger. By combining advanced cutting-edge geometries with expansive radius profiles, circle segment end mills mimic large-diameter cutter profiles with standard tooling sizes.
The cylinder is the container that holds the ball mill grinding process together. We size cylinders by their total volume when empty. When selecting a cylinder, it's important to pick a size that could potentially hold all of your grinding media, raw materials, and 25% of your total volume for processing space—what we consider the "working" …
