Re: VMC-100 central lubrication intervals

FRANCOIS JACQUES
 

Bonjour Martin

 Avec ta solution le graissage se fera même si la machine ne bouge pas donc?
 Les valvules sont des doseurs qui se "chargent" quand la pompe tourne et libèrent leur quantité d'huile ensuite et progressivement, ils sont numérotés en fonction de leur capacité mais je ne sais pas à quoi ce nombre correspond.
 Je suis parti pour rétrofiter la machine avec Mach3, comme malheureusement je n'ai pas réussi à piloter les cartes d'axe d'origine j'ai trouvé des drives chinois pour les moteurs 5 phases,à vide cela fonctionne bien. Pour la broche , comme la carte était manquante j'ai acheté une alimentation DC 180V pilotable en PWM , fonctionnement ok également, juste des vibrations à haute vitesse, je vais essayer d'équilibrer le rotor que j'ai dû redresser. J'aurais aussi la vis du Z à changer ultérieurement , elle a du jeu. Les roulements de broches sont aussi à remplacer. Je remonterai les axes cette hiver tranquillement, trop de choses à faire à l'extérieur l'été.
 Ma machine a bien travaillé, elle a fini sa carrière en entreprise comme taraudeuse mais elle est complète mécaniquement avec l'étau et des porte-outil dommage que le drive de broche manquait à l'appel

 J'angoisse un peu pour la gestion du magasin d'outils mais bon , je n'en suis pas encore là.

 Content d'échanger avec toi sur VMC100 bien moins courante que le Compact5 CNC.

Bon week-end, à bientôt.
Jacques.

Salut Jacques

Je viens d'installer une minuterie qui est complètement autonome du LinuxCNC et qui met en marche la pompe chaque fois le relais d'arrêt d'urgence est réinitialisé et alors après un délai ajustable.

C'est vrai qu'on verra s'il-y-aura trop d'huile dans le réfrigérant, mais il est plus difficile de découvrir trop peu d'huile. Ce week-end j'ai fait l'installation de la pompe et avant j'avais assumé que la quantité d'huile qui est diffusée sera caracterisée par la durée de marche de la pompe. Mais maintenant j'ai découvert qu'il y a des valvules de dosage à la sortie de la pompe qui laissent passer seulement une très petite quantité d'huile qui est indépendante de la durée de marche. La pompe peut marcher 3, 5 ou 8 secondes la quantité ne change pas. Ca m'a surpris mais comme ça il ne faudra au moins pas ce casser la tête sur la durée de marche.

Est-ce que tu vas aussi utiliser LinuxCNC ou as-tu d'autres plans?

I also have the same machine however I do not have the ACC. As far as I have found it requires the WinNC software, MSD disk, and appropriate licenses to function. I have yet to successfully run mine. I'm unsure what changes with the ACC. From what I have read on the machine it is capable of accuracy and finishes of high quality machines only slower since the machine is not built for production. Becoming familiar and tinkering with feeds and speeds will be your go to for achieving best results.

Thanks a lot. I have my ACC without cables, so I need to create those cables myself, looking forward to your manual.

It came with the desk, some documentation, some cables, a few floppies. Also big, heavy big keyboard/ control panel.

I know next to nothing about CNC. But not going to let that stop me!
I have been poking around and have learned a few things about this unit.
It has the ACC upgrade installed. I plugged a monitor and keyboard into it and it boots up ! Looks like Linux OS. I understand there was another PC with this (I don't have that).
My question is: what do I plug the Ethernet cable into? I'm guessing it's another computer, but what OS do I need? What software do I need (want).
Any help on this would be appreciated.

  I had one of these conversions with the ACC electronics. They charged like $ 4,000. for the upgrade. You will need to use the ethernet cable to another PC and have the operating system of choice loaded on the hard drive.
  What controller plates are installed on the console you received? They offered: Fanuc O, Fanuc 21, Siemens, Heidenhan, EMCOTronic panels. These plates are secured with the knurled thumbscrews. There is a dealer here in North Carolina that may be able to sell you what you need.

Re: 3.5 inch floppy drive controller

Keith
 

Hi Dieter,
Thanks for your message.
Whatever the circuit is it is not doing anything.
16 Volts appears on the transistor but the transistor is never switched on, I have removed and checked it.
I have assumed that the base is fed from the logic on the interface which is in turn triggered by the PIA on the CPU PCB.
As I have mentioned the interface card has a lot of components (see photo album) which I am slowly trying to trace what they do and how they are connected.
I have now also removed the black capacitor and tested it.
The 16 volt supply is directly on its terminals.
The 1000 micro farad cap is also OK but the 5 volt supply is not there.
I do not know the history of the lathe except that it did have some water damage so the Floppy and interface could have been wet at some point.
I will keep trying and hope that somebody somewhere has a schematic.
The lathe is otherwise in complete working order now.

Keith

Hi Keith,

Your schematic looks like a switching power supply:

Re: 3.5 inch floppy drive controller

Keith
 

Hi All,
I have added another photo to the album.
The photo shows a sketch of the 5 Volt supply on the interface board.
I believe that the component in my photos marked PJ220 is I think an encapsulated inductor.
The component marked PH I think is a zener diode, the full markings are PH37G.
My guess is that the 16 volt rail is switched on be the logic through the base of the transistor.
The 16 volts is then reduced to 5 Volts by the zener and the inductor act to prevent surges.
I cannot find any reference to either the PJ220 inductor or the PH37G components so all this is supposition at this stage.
I have trawled the net for interface cards but not found anything remotely similar.
Any ideas would be much appreciated.

Keith



Re: VMC-100 central lubrication intervals

FRANCOIS JACQUES
 

Bonjour Martin
 je possède aussi une VMC, en cours de rétrofit car la TM02 incomplète est inutilisable, ton idée est simple et acceptable à mon avis. Je pense que commander le graissage en ce basant sur le temps de fonctionnement de la broche (1h,2h?) serait simple à réaliser sans programmation, une commande manuelle (bouton poussoir lumineux) à actionner avant de démarrer un usinage complétera ta modification.
Tu verras à l'usage pour optimiser la temporisation, trop d'huile de graissage dans le liquide réfrigérant par exemple.
Cordialement.
Jacques.

Hi

I am currently retrofitting my VMC-100, it is a slow process but I think I'm getting there.

For the Willy Vogel central lubrication my plan is to turn it into a time-interval lubrication. I'm sure that LinuxCNC can do the same travel-based lubrication that the M2 control does (add up the travel on the guides and turn the pump on for 8 s after every 20 m) but I can still dive into that later if necessary, for the moment I try to keep the fancy programming to a minimum. I have also added a level control that starts beeping if the oil level in the reservoir goes too low, basically every other machine I know does that anyway.

The only thing I wonder is what interval might be appropriate. Has anyone else done it this way and what intervals are you using?

Re: Windows 98 hard drive help

wild_kow
 

I have mine installed on a Pentium II. The most important thing is that the computer does not have a built in video port. This causes conflicts which cannot be overcome easily. Look for a computer without the port built in but with the port on a separate plug-in card. Make sure that is a plain video card without added features. Also make sure the serial port is not doubling as a gaming port.

I spent many hours resolving issues. I bought identical computers for my PC50 mill and PC55 lathe. I got the mill to work but not the lathe, even with the same computer. I bought another almost bare computer for the lathe and that does work.

Hi All,
Windows 98 as far as I can remember came in two parts one floppy disk and one CD.
The floppy was the startup disk.
I think the later versions Windows 98SE may just have been on CD.
The startup disk and the ISO are available on the net.
I understand that there is a floppy disk version on Windows 98 which is/was available from MS but was 39 Disks.
There seem to be plenty of second hand internal IDE CD readers on various websites.
Best of luck,

Keith
