WO1998024588A1 - Method and apparatus for manufacture of

A method for manufacturing a quartz oscillator in which a quartz piece is ground as small, thin, and accurate as possible as to obtain a quartz oscillator, a quartz resonator or an optical lens for transmission and reception of a high frequency wave. An object (4) to be ground is bonded to a cylindrical, square or similar-shaped magnet plate (51) with adhesive (14) such as colophonium, resin

How eyeglass lens is made - material, production process

The machine grinds each lens to its proper shape and places a bevel around the edge of the lens so that the lens will fit the eyeglass frames. Water flows over the lens throughout this process. 10 If the lenses require additional grinding, the process is done by hand using a mounted power grinder.

Tumbled Stones: What are tumbled stones? How are they made?

The tumbling process usually takes a few weeks to complete in a rotary tumbler. Many people purchase rock tumblers to make tumbled stones as a hobby. Their tumblers range from inexpensive plastic machines that are usually loud and produce poorly-polished stones, to more durable metal machines with rubber barrels that are used by hobbyists.
