Hewing hall millgrav

[jif]

Hi there, Its nice to see a millgrav in good hands there. I worked at Newing-Hall as a fitter for 20 years and in that time I built or worked on just about every millgrav that we made. Its 10 years since the company went under but I think Pantograph Services of Leeds took over the handling of Newing-Halls affairs. I like the new spindle arrangment you have there, the large aluminium pulley on the original motor could sometimes cause trouble with vibration. The millgrav was one of my favourite machines because it did away with the old pantograph which could sometimes be difficult to set up and it was so easy to knock it out of square meaning a service call out to reset it. There were a couple of variations of the millgrav in that one had a solid aluminium plate holding the Y carriage and that had the slots for the ball blocks permanently machined at 90 deg to one another. The other had two aluminium plates on a spigot that allowed the two to swivel. We then had to manually set the plates at 90 deg to each other and dowel them with tapered pins. These machines were sold all over the world, The Jet Propulsion Lab USA (NASA) had one, Australia, South Africa, UK. Anyway, you will have to post some video footage of the machine working when its all up and running.

Hi Ian,

I've been using a PantoCut in my engraving business for nearly 10 years now. Would I be able to contact you to discuss what servicing & maintenance procedures I've been neglecting? I believe mine is also out of square. Or more specifically the spindle doesn't move perfectly straight in the x-axis, but instead has a slight arc to it. I guess the pantograph needs adjusting?

I hope you are still around and this request finds you.

Cheers

Rick

***UPDATE***

Just found and bought a MillGrav! These are very rare in Australia. They were over $80k (AUD) back in the 90's when new. Can't wait to put it to use!

Hi I am now the proud owner of a newing hall Millgrav, an older model but in beautiful condition, my question is about the controller and setting up, as there is no instructions to show how to use one of these machines, is there anyone out there in cnc land who may have some written instructions that they might want to share???

I am not used to posting stuff, else I would paste the text in, but it appears that is not possible. The filr I wanted to send you is an RTF, so in order to send it I have renamed it with the extension PNG. If you actuall get this you need to copy the file and rename it to an RTF. The file is called JLS_FIRMWARE_INSTALL Good luck!
No sorry, I can not see how to send this RTF, so contact me: - [email protected]

Stocky Welcome to the forum. I would remove your email because of the spammers out there. Also you do realise that this post is about 5 years old.

UPDATE - Overt the last 12months I have been able to successfully output G-Codes (full 3D) made in Fusion360 to the MillGrav via the Apex2 controller.
