Optical Surfaces - Newport

A dig is a small rough spot or pit on the polished or coated optical surface, originated from defect in the raw material or from the grinding process. Digs are defined by the actual diameters in tenth of a micron, or in hundredth of a millimeter. The number of maximum digs shall be one per each 20 mm diameter on a single optical surface.


surface grinding, but can also be used for offhand grinding of flat surfaces. Plain or beveled faces are available. Flaring Cup The flaring cup wheel, type number 11, is commonly used for tool grinding. With a resinoid bond, it is useful for snagging. Its face may be plain or beveled.


On the 3D surface of figure 2, scratches parallel to the grinding direction can be observed. They are formed by the grinding wheel, specifically by the larger diamond abrasive grains. Thus the abrasive grain (and its material, shape, size and distribution) has an …


The adsorbed water on the glass surface was distinguished from bulk water, trapped in interstices of silicate network, by D 2 O exchange experiments. The variation in the glass surface composition as a function of the chemical composition and grinding media (wet or dry) was characterized by XPS (X-ray photoelectron spectroscopy).

Mar 01, 2020· Slightly deep grinding depth produce lower surface roughness in MQL grinding, however, an excessive grinding depth leads to grinding layer separation and large peak-to-valley height. In contrast, the processing parameters have little effect on the surface roughness and morphology of glass-ceramic under SLA grinding with SiC and CeO 2 .


Sep 27, 2019· September 27, 2019. Also known as abrasive blasting, sandblasting is a surface finishing process that involves the use of a powered machine — typically an air compressor as well as a sandblasting machine — to spray abrasive particles under high pressure against a surface. It's called "sandblasting" because it blasts the surface with ...
