What it is

General reference — not yet source-verified

This class of machine performs precision material removal and surface finishing on flat parts. In semiconductor and optics production, such machines are used to control thickness, flatness, and surface quality on workpieces that must be processed with careful pressure and motion control.

Where it fits in the process flow

General reference — not yet source-verified

Equipment of this class is generally used where flatness, parallelism, and controlled removal are needed for fragile or thin parts. It is part of the mechanical finishing chain rather than front-end patterning or deposition.
