• Mirror Grinding Process Parameter Selection and Design

    Mirror grinding mainly depends on the precision of the machine tool cutting and grinding amount and wheel selection and dressing. This paper mainly studies the MG1432 high precision universal cylindrical grinder exploring the impact on the workpiece roughness through selection and design of various process parameters in grinding such as changing work table speed in dressing the grinding

    2019 3 8   Typically the primary mirror is made of glass. Pyrex is commonly used for the primary mirror because of its thermal stability but for small mirrors plate glass will work fine too. Telescope mirrors are relatively thick. The concave shaped face is made by repeatedly rubbing the primary glass blank over another blank called the "tool". The tool is equal in diameter to the primary. To grind away the unwanted glass from the glass blank and form the primary s concaveshape grit and water are placed between the "tool" and the primary face. Once the target depth of the concave shape is reached finer and finer grinding grits are used to slowly smooth out the new concave shape and to remove the scratches and pits left behind by the previous coarser grit.

Although a 16" tool works well with a 16" mirror for larger mirrors I would recommend a smaller tool simply because full size tools are heavy and awkward.
