Hewing hall millgrav

Hi New Member

I am sorry to be the bearer of bad news but my friend john has been unable to find any of the software that came with his machine, he informas me that he never used it anyhow as he uses a really weird program called casemate this outputs a hpgl type of language and machines in layers and colours...way too weird for me and this prog is well locked up with dongles

So perhaps you will go a similar rout to me......Wire cutters...................

I have this weekend i have got the MPG ( manual pulse generator ) working and calibrated along with the spindle inverter working under Mach3, i will soon be fitting processing power back into the box on Millgrav..

If you want any tips on how to do this i will be very happy to help

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

***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!
