Systems remotely polish and compress surfaces for working, including surfaces created through electrical discharge machining. A bridge may secure about the surface and carry a spindle that rotatably extends downward and carries a polishing assembly. The polishing assembly can push against the surface while polishing the same with larger amounts of force. The polisher can be moved about a perimeter of the surface and vertically. Systems may be remotely operated with a pneumatic slide, hydraulic motor, and/or stepper motor. Spotfaces formed from electrical discharge machining, including those in nuclear facilities and deep underwater, may have recast layers removed with such systems without manual or direct operator interface.

Disclosed are systems and processes for generating a finished or semi-finished lens, such as a spectacle lens, from a lens blank that includes an intermediate functional layer. Some embodiments of the process involve locating the functional layer and positioning the lens blank according to the location of the functional layer. The location of the functional layer can be ascertained by measuring the thickness of one or more layers of the lens blank. The lens blank can be surfaced on one or both sides to form a finished or semi-finished lens. Other embodiments are also described.

A polishing-pad laminated structure which allows for easy alignment of a through-hole of a polishing pad with a sensor head installed in a polishing table is disclosed. The polishing-pad laminated structure includes a polishing pad and a release sheet. The polishing pad has a through-hole located at a position corresponding to a position of a sensor head disposed in the polishing table. The release sheet covers an adhesive surface of the polishing pad. The release sheet is divided into at least a first release sheet and a second release sheet. The first release sheet has a surface area smaller than a surface area of the second release sheet.
