In this video I discuss spherical radius milling of both metal and glass. In addition the principle of the Loh Spheromatic CNC 120 radius grinder / mill is discussed. This machine can be used to mill / grind spherical surfaces on glass and ceramic objects. In the video I also use blocking wax. The wax was home made and consists of 1 part polishing pitch, 1 part colofonium and one part beewax. If you have questions concerning the machine, please leave a comment in the remarks.
I stumbled upon this channel by accident. I am amazed on the level of detail you provide. Amazing content!
Seeing the convex and concave surfaces pair so nicely together at the end... so good. soooo good hahaha
And its just really cool that because its glass you can see just how nicely they're paired .. SATISFYING!!
Onto the POLISHING VIDEO!!!
Wow! The machine looks amazingly well kept. Did you have to clean it up yourself, or was it already nearly perfect?
Thanks for sharing your work, extremely educational. I'm surprised by how strong that blocking wax is, I would've expected you would need to clamp down the blank to prevent it from moving during milling.
Interesting. Thank you for the view. Thanks for the explanation why the cylinders are used instead of servos or stepper motors and ball screws. I wouldn't expect the system to be more stiff by using cylinders!
Thank you for the explanation. 750 EUR for such a machine is a steal. I envy you :)
More videos please. Awesome work!!
Subsurface damage is also increased by feeding the diamond wheel too fast into the glass. I could generate nice smooth radii on a Strasbaugh generator with a coarse wheel by just feeding a little slower.
Woo, best channel for learning optics component processing in YT. Thanks very much Sir!
Really interesting videos, thank you. Your explanations are models of clarity..
Good ol' Loh. I regularly work with Satisloh single point diamond turning machines for eyewear. Cool to see the other side of things out there.
Cool explanation, wonder if those diamond angle grinder cutoff blades could be used? Wanted to make some mirrors for PIR sensors. Optical quality is not really needed? Given me a few ideas.
I imagine using hydraulics would also eliminate the backlash of a drive screw which would definitely help the the accuracy
So interesting! Thank you for sharing!
What an awesome machine
If you wanted to make optical elements out of Silicon or Geranium ingots - would you take similar steps but use a different tool? Or is Diamond the solution?
It is similar except that the swarf left behind makes the cleaning of the machine a huge mess (been there, done that).
hello super machine and incredible price :)
what is the biggest side of glass you can grind on this machine ?
very interesting video.
Thanks for the feedback. The largest diameter this machine can handle is approx. 130mm. So it is more suitable for lenses than for example for telescope mirrors, which are generally larger.
@Huygens Optics i was definitely thinking about telescopes :)
@Huygens Optics
good afternoon, write your email address
@ШтільОК No...
Have you ever done grinding of fluorite crystals on your Loh Spheromatic machine?
No, I've just used it for glass and glass-ceramics. I guess it should be possible since it is relatively soft material.
Many thanks for knowledge!
The last part looks like the process for grinding telescope mirrors.
Incredible
It's from switzerland. Great machine
750.00 €?!?!?! That’s about 1,000.00$!!!!!! I need a machine like that to experiment with custom camera lens 😂😂😂👍🏼
It is actually $820 with the current excange rate of 1.09.
@Huygens Optics Is normal price.
@Alex Stepanov No... No its not!
750 Euros for an optics making machine, ironically you must have seen them coming
I liked the NurdRage homage at the end
why does the larger base glass need to be centered?
because that glass base is the part in contact with the fixture in the machine. If you didn't have the blank and the base centred to each other then you would induce wedge in the blank and your radius would be off centre. If you were in mass production mode you would simply make a fixture the right size for the blank and skip the waxing altogether
"A very impressive stiffness" that is what she said.
That is what she said. Do you know what I am saying.
CNC --- Computer Numerical Control
The Machine is not from Germany, but from Switzerland.
nur weil die Rechnung aus der Schweiz kommt heißt es nicht das die Maschine nicht in Deutschland gebaut wurde. Die Firma hat in beiden Ländern Standorte und wurde ursprünglich mal in Deutschland gegründet.
Many a fortune made out of military surplus!
Some machine, must have cost 500k new
so why is the audio like that in the last few seconds? Are you secretly some sort of demon? Not that there's anything wrong with that
@Huygens Optics >>> 👍👍
Look to be from Switzerland (CH-4702, Soloturn), not Germany.
Sounds like mads mikkelsen
I would advise to buy any future lenses on Aliexpress. Cheap and saves you a lot of work

Your videos are great, please keep up the great work. I regularly fall down the "machining" rabbit hole in youtube, but these niche machines for optics are so cool!
