Milling is the process of machining flat, curved, orMilling machines are basically classified as vertical or irregular surfaces by feeding the workpiece against a rotating horizontal. These machines are also classified as knee-type, cutter containing a number of cutting edges. The milling ram-type, manufacturing or bed type, and planer-type. Most
Since my optical flat blank was once a grinding tool, it had a convex surface on one side. It took a little work to grind this surface to a flat one. I used the same range of grit sizes (120 grit to 5 micron) as used for mirror grinding to grind each surface. Note that I did not start with 80 grit. I did not need to.

The flat grind's primary bevel slopes linearly and slowly. This allows the full flat grind to pass through materials with more ease than other grinds who slope non-linearly (hollow), or at steeper angles (sabre). This is why the majority of kitchen knives are flat ground - so they can pass through food easily without much resistance. The full ...
images, is obtained. This ultra-smooth surface is less likely to harbour airborne contaminants or moisture than any other mill finish, and it is easy to clean. To maximise resistance to corrosion in the as-supplied condition, mill finish surfaces are acid cleaned (pickled) to remove scale formed during the hot rolling and annealing process.
2.1: Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used.

grinding on either the periphery or side of the wheel. Tapered Tapered wheels, type number 4, take tapered safety flanges to keep pieces from flying if the wheel is broken while snagging. Straight Cup The straight cup wheel, type number 6, is used primarily for surface grinding, but can also be used for offhand grinding of flat surfaces.
Grinding: Grinding is the operation of removing the metal in the form of minute chips by feeding the work against a rotating abrasive wheel known as the grinding wheel. Both internal and external surface of a workpiece may be ground by using a special attachment mounted on the cross slide.
