My Zeiss grinding and polishing machine

The movie shows the Zeiss machine in all its phases, putting together notes, drawings and films that make up the story: from initial idea to the project, manufacturing of machine parts to the assembly, and again from the first test until the first job of a primary mirror of 400mm telescope.
The Zeiss machine is this: any optical reflection or refraction derived from conical shape (flat, sphere, ellipse, parabola, hyperbola) can be obtained from his work, although in the final stages, the human hand remains irreplaceable.
The project started some years ago, I have enriched experience and many aspects
the processing of optical drive is yet to be discovered, but already
satisfied with the results thus far obtained.
A forthcoming movie come alive in the processing, touching many aspects
optical processing in the variety of movements and speed.
Good vision.

Il filmato mostra la macchina Zeiss in tutte le sue fasi, mettendo insieme appunti, disegni e filmati che costruiscono la storia: dalla prima idea al progetto, dalla lavorazione dei pezzi meccanici al suo montaggio, ed ancora dal primo collaudo fino alla prima lavorazione di uno specchio primario da 400mm per telescopi.
La macchina Zeiss serve a questo: qualsiasi ottica, a riflessione o a rifrazione con forma derivata da coniche ( piana, sfera, ellisse, parabola, iperbole) può essere ottenuta dalla sua lavorazione, anche se nelle fasi finali, la mano delluomo resta ancora insostituibile.
Il progetto partito qualche anno fa, mi ha arricchito di esperienza e molti aspetti
sulla lavorazione delle ottiche a macchina sono ancora da scoprire, ma sono già
soddisfatto dei risultati sin qui ottenuti.

Un prossimo filmato entrerà nel vivo della lavorazione, toccando gli innumerevoli aspetti
della lavorazione ottica nella varietà dei movimenti e velocità.
Buona visione.

Very nice job. The best hommade machine I ever seen!Congratulation!

@attila8685

Thank you.

I realized it according on its basics scheme.

Little information exists on this machine, everyone must make his own experience.

I hope to publish my experience in the future to fill this gap.

Are you an ATM too?

Thanks for your sharing.

Do you have any experience Paraboloid Mirror grinding in CNC machine?

What can you say CNC grinding and polishing?

[RICCARDOSPADA]

@egeotomasyon

I've no experience in CNC machine but I can say that you don't need this kind of machine to work paraboloid mirrors, a Zeiss machine or Mirror-o-matic one is enough for ATM using normal diameters.....

hi, i'm from Spain.

how much € would you ask for a 16 / 20 inch mirror?

kind regards

Hello.

Unfortunately it is not considered the idea of working for third parties, at least for now, because of the limited time available, it is not my profession but a hobby, I'm sorry.

Right now I ‘m working my mirror 75 cm for a project that will engage me for some years in building a telescope.

Only a craftsman who has made a a dozen or so mirrors by hand and feeble machine

can truly appreciate what you have created. I thank you for raising the level that Porter

started so many years ago. May you go on to create even more wonderous devices.

Thanks for posting this video. Your an excellent engineer and craftsman. Maybe one day you'll sell plans of this machine.

Could you tell something about the bearing that is shown from 1:46 to 1:50, it's the bearing the turntable rests on. Was this completely build by yourself or did you purchase the ballrace?

Ciao, bellissima macchina!!

Quanto costerebbe fare uno specchio con la tua macchina, anche solo la lavorazione del vetro (diciamo un 400 mm giusto per avere un'idea), dato ho scoperto solo ieri la possibilità di autocostruire questi elementi e dato che mi stavo trasferendo in Albania dove ho la possibilità di trovare luoghi completamente buii così mi è ritornata la voglia di un telescopio. Grazie!!

Fantastic passion.

Like!

@RICCARDOSPADA

Yes I do! I have made earlier a lot of mirrors. Now I am interested in evaporation. I have two grinding machines, and two coating machines. The biggest has 50cm chamber.

Check my videos.
