An Introduction to the Optics Manufacturing Process

Loose abrasive grinding uses inverse spheres of the same radii ground together so that the hills and valleys on the optics will wear away to produce a true sphere. Slurry flows in between the blocked parts and the spherical tool to keep the parts cool and wash away debris created during the grinding process. Polishing

DEM investigation of SAG mill with spherical grinding ...

In the ore milling process, the ore particles are usually irregular polyhedrons, and the grinding media are often spherical. The need for accurate simulation of this process calls for a contact algorithm between the polyhedron and sphere, achieving a balance of accuracy, stability, and efficiency. For this purpose, we propose a polyhedron-sphere contact model based on the …
