I finally decided it was time to build a machine to help me grind the edges of the blanks true and round. This is my homebuilt edge grinding machine for grinding
Unlike typical sandpaper strips, the socalled sandpaper used in grinding is actually a mixture of grit and water. A layer of grit is sprinkled on the blank. Then water is
Obtain the right glass. Choose solid grinding tools. Choose the best position to work on mirrors by hand. Grind the back flat. Try and prevent astigmatism.
Building a fixed post mirror grinding machine. I'm fascinated by those who can grind and figure their own mirrors for reflecting telescopes. With the availability of kits

I finally decided it was time to build a machine to help me grind the edges of the blanks true and round. This is my homebuilt edge grinding machine for grinding down my homecast mirror blanks. Click to see the whole project. This is a 12.5 inch diameter, 1.5 inch thick, lightweight honeycombback telescope mirror blank that I made myself.
Obtain the right glass. Choose solid grinding tools. Choose the best position to work on mirrors by hand. Grind the back flat. Try and prevent astigmatism. After having the ground and face of the mirror flat through the 220, you are good to begin rough grinding the curve into the mirror. Do some fine grinding.
Rotational speed starts from 50RPM to 1,000RPM. Other mirror grinding machine from Alibaba include electric car polishers. These come with different polishing pads for removing scratches, swirls, and paint defects from cars. Operation speed is within 2,800 to 7,200 operations per minute (OPM) range.
This is the focus of all your work you will turn this flat piece of glass into an accurate parabolic telescope mirror. We recommend a full thickness Pyrex blank for mirrors up to to 12" in size. Fullthickness means the diameter
Solid concept, but there is a reason telescope mirrors are made by hand — machines are too regular, whereas humans are random and flawed. the problem with a machine is that it develops patterns
TECHSPEC® Precision Parabolic Mirrors are available in sizes ranging from 3" (76.2mm) to 16.25" (412.8mm) and are ideal for a wide range of applications. These parabolic mirrors are offered with protected
Our astronomical telescopes “Gemini” combine the advantages of the classic Dobsonian mount, but with an improved, lightweight and easy to assemble truss design. The advantages of open design are well known low weight, mobility, fast tempering of the primary mirror, low space for transportation and storage. Our astronomical telescopes

Remember to float the mirror on newspapers, or an old blanket folded up, or outdoor carpet. Rotate the mirror a 1/3 turn every 10 minutes. Use 1/3 'W' strokes if the tool is the same size as the mirror and
Just grinding the telescope mirror probably took 80100 hours for me, but I was learning a lot and taking my time. For a mirror I'm making now I found this weird counter thing at a garage sale and used it, but marks on piece

A better way of showing how accurate a telescope mirror is by Strehl. The strehl percentage indicates the amount of light which is returned by the mirror, within the central peak of the Airy Disk. One of the most expensive mirror makers around is R. F. Royce. R. F. Royce does not let his mirrors out unless they have a strehl of at least 96%.
Mirrormaking at Stellafane. Richard Koolish. In general, no. Making a telescope mirror is a twostep procedure. First you generate and refine the curve in the glass, and then you carefully modify that curve, in the process known as figuring, to give the mirror’s polished surface the necessary paraboloidal shape.

The mirror also has to be stable over time and be self supporting to some extent. Semi equipment starts with a flat wafer and makes >20nm features (transistors) and doesn't create a surface. While the wafer is large, the die (chips on the wafer are small). Not a match for making a telescope mirrors. So1) can you 3D print a sphere or parabola
Nichol Optical and Oldham Optical are two other UK sources; Northcote Hill Farmhouse. Oldham Optical Web Site. as you've already drawn the line at making your own mirror, I'm sure you understand the reason for the prices. Thank you Yes, mirror grinding is a long slow and labourious process, I know, so I certainly understand the prices.

When I decided in 2009 after a tenyear break to get into mirror making again, it quickly became clear to me that I would need to construct machine, as hand grinding big mirrors is not something very beneficial
