history of surface grinding process

Surface grinding - Wikipedia

Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional purpose. The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, and a r

What is Surface Grinding? - Info Bloom

Feb 12, 2021  Brad Chacos Date: February 12, 2021 Worker . Surface grinding is an abrasive machining process that involves securing an object to a holding device known as a chuck, then slowly moving the surface of the object across a fast-spinning grinding wheel. The chuck is part of a table that moves back and forth on the machine.

As the polishing process continues, the pitch will slowly conform to the shape of the optic so that the surface of the optic is smoothed out, but its overall radius is not changed. To aid in removing debris, grooves are cut along the pitch to allow slurry to flow more readily between the tool and the optic.

Lenses - Engineering and Technology History Wiki

Oct 15, 2015  After grinding, the lens was polished, sometimes using the same lap that had been used to shape it. That required preparing the lap surface to remove roughness. In some cases, it was done by overlaying the surface of the lap with a specially prepared paper. In other cases, a method still used by amateurs to polish telescope mirrors was used.
