Joy of Mirror Making: Rough Grinding - BBAstroDesigns

The curve is ground into the mirror face using a grinding tool. The curve is pre-generated for you. The curve is created by slumping the blank in a kiln over a mold. Here are 42 inch [107cm] and 30 inch [762cm] mirrors slumped and annealed to F2.8 ready for fine grinding. The first method is by far the most popular.

The ring ought to be roughly 1/3 to ½ the diameter of the mirror, and grinding center over center strokes with it using large grits, such as 60 grit, will curve generate a mirror. You will have to cast a tool for it when finished. Below is a photo of using a barbell weight on our mirror making machine to curve a 32" f/3.67 mirror to an f/3.1.

The final grinding and polishing take place on the LPM (Large Polishing Machine) located at the north end of the Lab. Although previous mirrors have been completed on the LOG (Large Optical Generator), the LPM has more precise controls that make the final polishing of the mirror surface easier (if that is possible) than the LOG.

New Grinding Methods for Aspheric Mirrors with Large ...

In this paper some new methods for grinding toroidal mirrors, elliptic and circular cylinder mirrors with large curvature radii are investigated. By using the grinding methods proposed here, we successfully obtain aspheric mirrors made of SiC, with higher precision in shape accuracy and low surface roughness, as R max = 20-40 nm, R a = 2 ~ 5 nm.

Page 2 of 2 - Curve generating - posted in ATM, Optics and DIY Forum: I use a sine table and drill press and diamond hole saw like Dave. My first iteration had the turntable for the mirror just on Teflon to turn. I had to turn it by hand slowly and it left some big generation marks that needed to be removed with a decent amount of 80 grit work.

Waite Research :: 20" F3.0 Project "J"

You can see the "swirly" marks left by Newport's diamond generator. You need to grind with 25-micron until those are all gone, and then a little more to get rid of sub-surface damage. For this, I ground with about 25 to 35 pounds of weight added on top of the mirror, running the fixed-post grinding machine full out at 60 rpm's.
