Newport Glass Works, LTD. Grinding, Polishing

The tool need not be as large as the mirror. You can use a tool 75% of the mirror diameter without much difficulty.

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

22" mirror grinding - Reiner Vogel

The grinding tool was made of regular plaster with a diameter of 450 mm and a thickness of 30 mm at the edge. The plaster should not be too viscous to allow air bubbles to escape during casting and to give a smooth surface of the tool. Unlike on the picture, it is better to put a thin plastic bag between plaster and mirror to avoid sticking the plaster to the glass. The tool was thoroughly

Build your own telescope part 1: The mirror –

Rough grinding. This step is about making one side of the glass concave. It will give your mirror its overall focal ratio. If you make the centre deep, you will end up with a fast telescope (e.g. F/D = 4) well suited for deep sky observations. On the opposite, a shallow mirror (e.g. F/D = 8) will be performing very well on planets and the moon. The theory behind grinding is that you can remove

Study on a 5-axis precision and mirror grinding

The mirror freeform grinding may be parameterized by material behavior, tool size and posture, grinding conditions and abrasive tool performance. On the base of virtual ball-end algorithm, the form errors compensation enhances the mirror-ground freeform accuracy by 26%. It is confirmed that the 3-μm-size diamond grinding without on-machine truing is feasible to fabricate the precision and
