What is Single & Double Side Fine Grinding?

Fine Grinding (flat parts – single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is

Fine Grinding - an overview | ScienceDirect Topics

Abrasive flow machining (AFM) is a fine grinding process with rather low material removal rates. AFM is mainly used for polishing, deburring, and defined edge rounding and, due to the fact that a viscous carrier for the abrasive media is used, can be used to machine difficult-to-access cavities, inner contours, and undercuts in a reproducible manner [52] .

In the second washing step, 2 g of the ground sample was placed in a capped Erlenmeyer flask filled with 300 mL of water/ethane (50/50) solution and stirred for 4 h at room temperature on a magnetic stirring apparatus (524G, Meiyingpu Shanghai, China) to completely dissolve the salt additives.

An Introduction to the Optics Manufacturing Process

2008-10-31 · The first step in the lens manufacturing process is generation. This process will ‘generate’ the shape of the lens into the blank, getting close to its final shape, size, and curvature. Although an outdated process, one generation technique that is still used today is loose abrasive grinding. This involves using various grit sizes mixed with water (this mixture is called a slurry) to remove glass. The larger the grit size, the more glass is removed, resulting in a faster removal rate. However, a rougher surface will be produced. Therefore, generating begins with large grit
