A. Bone Milling Operation
For milling bone, after installing the Battery-power-pack, the Rotor, the Blade, and the Catch-
container; the bone chip is manually placed in the bone chip container of the rotor. Subsequently
the Safety Cap is installed and the on/off switch activated. The catch-container catches the
milled bone morsels.

B. HR500 Bone Milling Process

i. Cut- and-trim process
The rotor, rotating at high RPM, creates radial centrifugal forces that are acting on the bone
chips forcing the chips against the blade. The rotor sweeps the bone chips over the surface of
the blade that allows the cutting teeth of the blade to cut portions of the bone chips. The ribs
of the rotor trim the previously cut-portions to smaller than the sizes of the apparatuses
located in front of the cutting teeth. The properly sized morsels are forced to eject themselves
through the apparatuses, falling into the catch-container.
