New Grinding Methods for Aspheric Mirrors with Large Curvature Radii Z. Zhong, The institute of Physical and Chemical Research/Japan - Submitted by T. Nakagawa (l), University of Tokyo/Japan Received on January 14,1992 ABSTRACT: In this paper some new methods for grinding toroidal mirrors, elliptic and circular cylinder mirrors with large …
The center of the mirror is the most likely to be contacted by any motion, so it is abraded more frequently and becomes the deepest point, while the edges are worn less. The distribution between "less" and "more" is spherical. I can at least understand the process of grinding or lapping a surface flat.
spin grinding a slumped mirror - posted in ATM, Optics and DIY Forum: so after taking a few years off from the hobby to get my wife well i have completed my spin grinder and am ready to tackle the 14 honeycombed mirror that you see as my avatar i had it fused to shape many years ago and it is slumped to an F5 curve. i have not used a spin grinder as yet all my …

A look at a 15" Telescope Mirror, with Ronchi history. The fabrication of this 15" F4.5 primary telescope mirror began with a planoplano blank. I used my own diamond grinding equipment to generate the rough curve here. After the generation, I poured a steel grinding tool and used #40 silicon carbide abrasive to get the mirror close to the ...

The process of grinding a 14-inch mirror for the telescope he was building inspired him to find a faster grinding technique. Every learned about spin-casting liquid materials and thought the method could apply to making concave mirror-shapes out of plastic. "As a liquid spins, it takes on a parabolic, or dish, shape, the necessary shape for a Newtonian telescope …
This is as interesting to me even if I were to grind some much smaller mirror say 10-12 inches as it would be to scale up to whatever size blanks could ever be found in the future. I've glanced through books on telescope making and although the nature of the project interests me, spending many hours hand grinding a mirror is difficult to justify with a busy life and busy …
Our telescope mirror grinding kit includes clear-cut round plate glass blanks of desired size & thickness along with Carborundum a.k.a Silicon Carbide (SiC) and Aluminum Oxide (Al 2 O 3) assorted abrasives, rosin & beeswax for pitch and cerium oxide as a polishing compound.

Hand grinding takes care of this automatically. For the smaller sizes of mirrors you will also want to be able to exchange the mirror and tool positions from time to time as the grinding progresses. You should research the back issues of the astronomy magazines (Astronomy, Sky and Telescope, etc.) as well as the books on the subject in the ...

SKM-mirror grinding research. Mechanical dressing of resin bond diamond grinding wheel ... Usually, grinding of hard and brittle materials causes microcracks which deteriorate surface quality. Thus, the transition from brittle-to-ductile material removal is considered to be of great importance for ultra-precision grinding. Much research effort has been spent to identify this …
Your role in grinding and polishing a Starshine mirror is vital to making the satellite visible. These aluminum mirrors are easy to grind to a very flat shape and to polish to a beautiful finish; however, they are also extremely easy to scratch, if you do not keep everything absolutely clean. So, please follow these instructions as carefully as you possibly can. We're depending on you. …
I know that they recommend a small slow mirror for a first grind, but I know you've bucked this trend so I was thinking 10 or 12" and around f/6, I need to research balance and height before definately aiming for a certain F/ratio. I might follow in your footsteps in terms of just going for a big grind Dan
