Obtain the right glass. Choose solid grinding tools. Choose the best position to work on mirrors by hand. Grind the back flat. Try and prevent astigmatism. After having the ground and face of the mirror flat through the 220, you are good to begin rough grinding the curve into the mirror. Do some fine grinding.
Diderot's encyclopedia, published in France from 1751, includes illustrations of various devices and tools used to make lenses for a variety of optical instruments, including spectacles. The grinding machine has a solid wooden frame similar in principle to that of a potter's wheel. A large flywheel is driven by a hand-operated crank, with a ...
In order to do the precision grinding of optical aspheric lens, it is essential to achieve high quality surface roughness. Experiments show that the contacting area between the wheel and workpiece in a grinding process is critical to influence the surface roughness for a fine grit size resin bonded wheel. The precision grinding are performed with BK7 optical lens.
The most common way of correcting vertical imbalance is to induce a vertical prismatic effect in the lower half of one lens. This type of correction is referred to as bi-centric grinding, or slab-off. It can be used to correct for imbalance amounts ranging from 1.5D to 6D. Slab-off provides base up (BU) prism and is applied to the most minus ...

The manufacture of a lens element that is pure enough to be used for photography is pretty complex. You need materials with adequate purity, light transmission, and hardness, not to mention a fair bit of precision in your grinding mechanism to ensure you refract light enough to focus it where you want it focused, and do so evenly across the surface of the lens.
