Mirror Grinding Machine

My Mirror Grinding Machine. For a long time I've wanted to build a machine for grinding telescope mirrors. Dennis Rech's M-o-M designs finally inspired me to just get up and do it. Over the years, I'd been collecting motors, gear boxes, pulleys, etc. Most of them came from industrial junk yards. To use these parts, I had to modify some of Dennis' plans. How I did it is described below. This ...

Joy of Mirror Making: Rough Grinding - BBAstroDesigns

The center will deepen during the first stage of fine grinding as contact is achieved across the mirror face and fine grinding tool. On larger mirrors, the ring tool may leave the zones part way to the edge a little underground. For these mirrors, as you near the depth, you can alter the strokes to be off-center. This will prevent the mirror zones partway to the edge not being ground deep enough.

Cox, then Co-editor of the Gleanings for ATM’s column, proposed that the test be called the Mobsby test.

Fixed-post machine grinding is where the mirror is on a turntable rotating around 20 PRM [speeds vary], and a 75% tool is on top. They are already curve-generated. The tool is hanging over the mirror by 1/6 the diameter of the tool, or about 1/8 diameter of the mirror, and is fixed in this position. The motor turns the mirror and the differential rotation enables the grit and water to grind ...

01/11/2011  An alternative, which seems very popular with home machine builders, involves rotating the mirror at a relatively high speed whilst the tool has minimal movement or is fixed (as in the case of Gordon W’s machine). The trick is to place a correctly sized tool in the appropriate position to ensure an even grind/polish. With both machines I am assuming the mirror is being worked face up with a ...
