Mirror-O-Matic grinding machine. When I decided in 2009 after a ten-year 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 for the hands of a musician.
One machine is designed for grinding concave mirrors of small focal length. The other machine, a much larger piece to implement, grinds mirrors of large focal lengths. Though Leonardo da Vinci creates sketches of mirror grinding, one crucial and logical question to ask is whether he used such mirrors in his artwork or drawing.
The mirror machine came to me as a result of astronomical horse-trading, swapping a large GEM mount and a 8 Newtonian OTA for the machine as it was and a start kit consisting of two 6 blanks and the grit, rouge and pitch to manufacture a mirror. The grinding machine had been built to the design of the mirror-o-matic design of Dennis Rech ...

The original grinding machine was used under the sponsorship of Hale to grind a 60-inch mirror initially intended for the Yerkes Observatory. The grinding machine was moved to Pasadena in 1904 to complete work on the mirror at some point it was transferred to the California Institute of Technology.
Grinding Machine for Large Telescope Mirrors. I designed and built a grinding machine for mirrors up to 42 inches 1.1m in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work. The machine can also work smaller mirrors if the drip pan is moved to the fast shaft on ...
In his Codice Atlantico, Leonardo offers two of sketches of mirror making machines . One machine is designed for grinding concave mirrors of small focal length. The other machine, a much larger piece to implement, grinds mirrors of large focal lengths. Though Leonardo da Vinci creates sketches of mirror grinding ...
A good starter size is the 150 mm 6 mirror. A 200mm 8 will also work. Most ATM books and websites recommend a Pyrex mirror blank, but in my opinion, annealed plate glass is better for this first, learn and practice mirror.It is cheaper, it is softer and grinds faster, needing less abrasives and with these small sizes, the low expansion glass like Pyrex has no practical visible at ...
Much is also unchanged - mirror grinding techniques are very similar to those written up by Porter and Ingalls in the 20 s and 30 s. Many amateur astronomers still choose to fabricate their own instruments, for the pride of accomplishment, the gaining of knowledge and the insurance of quality.

Oct 01, 2016 The mirror grinding of curve surface may be fabricated by the ELID grinding , but the electrolytic dressing system of superfine diamond wheel was complex and inefficient. It has been known that the ductile-mode mirror grinding depends on the grain cutting depth less than the critical cutting depth for the transfer from brittle-mode removal to ...
George Willis Ritchey built this mirror grinding machine at the Yerkes Observatory in Williams Bay, Wisconsin, in the late 1890s. Under the sponsorship of George Ellery Hale, the machine was used to grind a series of telescope mirrors starting with a 24-inch and then a 60-inch mirror for a telescope initially intended for the Yerkes Observatory. The grinding machine was moved to Pasadena in 1904 to
The mirror or lens grinding machine is a masterpiece of mechanical engineering. It has several gears in mesh at all times and also has several variable settings built into it. This machine was most likely designed by Leonardo while he was either investigating the different ways that light reflected off things or maybe he was planning on inventing a telescope or some other optical device.

The M-o-M is a marvellous machine due to its simplicity and yet refined design. It is extremely flexible accommodating mirror sizes from 4 inch up to 20 inch with slight modifications and can be used for all three steps necessary in producing a mirror. That is you can use it to grind, polish and figure your optics.
Mar 08, 2021 Mirror grinding is a grinding that the surface roughness of the workpiece is Ra 0.01m, and the light is like a mirror after grinding, so it can be clearly photographed. The flatness of the grinding surface is not greater than 3m 1000mm. The surface machining of high precision and high added value parts requires mirror grinding.

I had an idle mirror grinding machine a modified MOM 20, so I volunteered to grind and polish his blanks and check for strain using the cross-polarized light test. Soon, three plate glass blanks arrived, two 10 inch and one 7.5 inch. They looked pretty bad. They showed a lot of strain where Horace had taken a belt sander to them.
