  • 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.

  • Grinding Machine for Large Telescope Mirrors

    Grinding Machine for Large Telescope Mirrors I designed and built a grinding machine for mirrors up to 42 inches [1.1m] in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work.

    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.

    A good starter size is the 150 mm (6") mirror. A 200mm (8") will also work. Most ATM books and websites recommend a Pyrex® mirror blank, but in my opinion, annealed plate glass is better for this first, "learn and practice" mirror.It is cheaper, it is softer and grinds faster, needing less abrasives and with these small sizes, the low expansion glass like Pyrex has no practical (visible at

    Good grinding technique will produce a spherical shape, therefore the only important property needing measurement is the depth of the concave surface at the center of the mirror. The easiest way to do this is by placing a stiff metallic straight edge across the mirror face center spanning edge to edge.
