Almost ;-) Myford Super 7 Long Bed, 1hp, 3 phase, at 2000rpm and 0.2mm DOC, manual feed so the material comes off like angel's hair on fire...

Interesting result. Is the original bit of machining as rough as it looks? I know that photographs are often misleading when it comes to surface...

Hi Ravi Sorry for not replying sooner but have been busy machining parts for my gas turbine. I see you have carried out some serious mods to your...

I'd love to help but as M_C says, how can we provide help when we know nothing about the system, what it is, what's wrong with it etc? You provide a...

You'll have to wait and see, you don't have the rubber mounts normally associated with single phase machines, they help significantly in smoothing...

Thanks for the link. It sounds like Fred is offering the "double floating" variety of bearing then.

I had a single phase 2.2kw motor handy... Do you think I'll see the lumpy torque in the surface finish?

So am I right in thinking that this kind of setup is essentially working like having fixed bearings at both ends? - there's an obvious advantage in...

I helped a friend to fit a VFD to his and convert the rest of the switch gear to 240, why on earth would you want to fit a motor providing "Lumpy...

Well, where you were educated it was obviously somewhere where it was customary to pose questions whilst providing insufficient information to...

Sarcasm the meaning: The use of remarks that clearly mean the opposite of what they say, made in order to hurt someone's feelings or to criticise...

I don’t have detailed plans that someone could follow. I’ve made changes along the way and it is quite a complicated machine. However I plan to put...

he's being sartcastic because you have given no details as to where you are and what machine and software you need setting up. Details will help get...

Updated.

Yes, 1c1 and 1c2 are the fwd/rev contactors operated by microswitches which are in turn operated by the motor control lever on the carriage. See...

My bad - 1C1/1C2 are the relays shown at the bottom of the schematic? Then use two pairs of the 1c1/1c2 contacts to provide the change-over for...

The schematic - yup, though I'd be interested in the 1c1/1c2 arrangement - these are contactors?, what actuates these? a mechanical...

So this is what I think I need to reverse the single phase with the two contactors I have in the machine: I took the lamp off, built like it's...

I used that setup on both sides of my screws and was very happy from it. I don't see the point of using floating end on a properly made CNC, given...

just realised that link is the same lol, will double check its a public vid :-)
