Best lenses and mirrors are both made by grinding the surface Start with a mirror or lens blank For mirrors only surface needs to be good Typical mirror want pyrex (eg BK7) Then need a tool blank poorer glass amp; softer glass Place mirror on top tool Now add grinding compound (grit) between tool amp; mirror Grinding moving the mirror over the tool with grit
MirrorOMatic grinding machine. 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 for the hands of a musician.
Making different components such as Mirrors (glass mirror, furniture mirror, concave mirror, convex mirror etc.), Painting of glass, Polishing of Glass, and Periscope etc. within required accuracy. 2nd Semester The practical training, it starts with operation of Lens Format cutting machine, Lens Grinding machine Opto lab. Followed by different operation such as Curve generation, Grinding
Second, the precision and mirror microgrinding along with the form errors of freeform microlens array was observed on the base of the transfer from brittlemode removal to ductilemode removal.
FREE Mirror/Lens grinding machine and various supplies, blanks, tools. I acquired this a few years ago from the son of the former owner of Optica, who produced lenses and mirrors in Oakland CA for over 40 years. WYSIWYG. The wiring could be overhauled, but the mechanisms seem sound if not in need of a little TLC. Variacs could be replaced/modernized. The whole thing is very stout and shows
Grinding Machine for Large Telpe Mirrors I designed and built a grinding machine for mirrors up to 42 inches [] in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work.
A good starter size is the 150 mm (6quot;) mirror. A 200mm (8quot;) will also work. Most ATM books and websites recommend a Pyrex#174; mirror blank, but in my opinion, annealed plate glass is better for this first, quot;learn and practicequot; 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
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 telpe or some other optical device. Here
My Mirror Grinding Machine. For a long time I''ve wanted to build a machine for grinding telpe mirrors. Dennis Rech''s MoM designs finally inspired me to just get up and do it. Over the years, I''d been collecting motors, gear boxes, pulleys, etc. Most of them came from industrial junk yards.

This device consists of a frame 51 which carries a set of projection lenses 52, a mirror 53 and a plane or screen 54 upon which to project. It is an advantage to have the projection device provided with an attachment 55 for a magnifying glass. In order to have no light entering from the outside upon the projection device the latter is covered by a casing 56. The optical profile grinding

I bought one of the B amp; I mirror machines back in 1969 when hey first came out and ended up selling it a few years ago. It wasnt anything spectacular but it was kind of neat. I just bought a couple of Bob Piekels books and saw a

MIRROR GRINDING MACHINE. I made my first mirror grinding and polishing machine over thirty years ago. It used the working principle of the machine illustrated at quot;Aquot;, Page 163, quot;Amateur Telpe Makingquot; Book 1. A bowl which rotated was fitted to the spindle. I also built another machine
