Re: TU150U in need of TLC

That was in a sorry state! On the plus side, when you've finished you'll have a fantastic Lathe!

I'm envious of your power chuck & parts catcher!

It looks like a good candidate for a new control system as yours looks more antiquated than even my Fanuc.

Best of luck with the restoration.

Re: New Cyclone - need phase converter advice.

Just as a quick update, 2 Months on from getting it up and running on 230V 3 Phase - it's still running nicely! I've pushed it quite hard a few times and it has not complained - and the magic smoke has not escaped! £500 Inverter + £100 choke is all you need! The 10Hp is only needed for a few seconds...

Re: Cyclone X Axis Dovetail Repair

You've made a nice job of the repair. Sadly, I don't have any Ballscrew ideas other than someone like https://www.cnc4you.co.uk/Ballscrew There's are not bad quality - but you have to machine the end yourself to suit. Seeing what you've done above, this is not going to be a problem for you! To be fa...

Cyclone Dripfeed - Possible?

I'll answer the 'why' question first. On a previous machine, I made a little Arduino powered box which had a number of wizards for quick machining jobs selected from a touch-screen. Things like facing, chamfers, radiused ends & slots, much like the wizards built in to Mach3. You dialed up what you w...

So it would be usefull for me to know what the rpm range and pulley ratio were on the original 2.2kw machine
Mine is 2.2kw and the spindle will go up to 5000rpm (at least, that's what it says, I have no way to measure, but it looks scary fast!).
Pulley ratio looks 1:1

Re: New Cyclone - need phase converter advice.

Good news - I have it running! To make yours run, you will need a 10Hp / 7.5kW Phase converter. I used a digital converter, I don't know if it will work with a rotary, but it seems likely. The Cyclone needs 415v to operate, but can be made to run on 230V 3 Phase (see later). The simplest option is t...

Re: New Cyclone - need phase converter advice.

That's kind of the conclusion I'm coming to! Looking at the (simplified) schematics I have: Coolant Motor - 415v 3Ph The spindle, spindle fan and axis drives - 220V 3Ph Fanuc - 200v + 100v 1Ph (1.1kVA) Control & E-Stop - 110v 1Ph (200VA) Tool Post - 110v 1Ph (300VA) Transformer box fan - 24v 1Ph It'...

Re: New Cyclone - need phase converter advice.

Thanks Pete. So, mine is a Cyclone P - that's a start! The current quoted in the literature as well as on the rating plates seems random! I've seen rating plates as low as 16A and up to 29A where the literature is generally 16 to 20A. Have any of you run one on a phase converter? If so, what size / ...

Re: New Cyclone - need phase converter advice.

Unfortunately, I don't have the manual - or much else other than the machine.

27A is possible as production mmachines have high acceleration / deceleration.

Re: New Cyclone - need phase converter advice.

I've just spoken to David from Drives Direct - who has quoted me £3995.00 +VAT for a digital phase converter to run the Cyclone. Is that realistic? or was that him trying to get rid of me? I'd appreciate any advice. I could just convert the whole thing to Mach 3 - and that's looking promising today....

New Cyclone - need phase converter advice.

I previously owned an Eazyturn3 - which was fantastic (post Mach3 conversion). The only thing I didn't like was no ATC. I've now bought a Cyclone which is obviously a much more grown-up machine. 20181210_081429.jpg 20181210_081448.jpg I don't know much about it - I don't even know the model number! ...

WANTED: Denford Cyclone F

I'd like a cyclone with Fanuc control & 35mm through the bore.

I have a budget of £3-4k depending on condition, tooling etc

Anything considered.

I'd quite like a Triac with ATC too. Similar budget.

Do any of you have assembly drawings or photos of the cross slide assembly to see if adjusting the backlash is even possible?

Re: CNC Virgin

The CNC4PC board will talk directly to the original stepper drivers without a problem. You need to identify which pins on the drivers are step, direction and ground then trace these through whatever lead connected these to the original computer board. It might be best to buy a socket, solder it to a...

It is!

It's a 125mm HBM chuck. The back of the chuck is threaded to screw on to a Myford (and obviously the Indexer has a Myford thread sticking out)

Re: Easiturn power chuck wanted

The chuck has a pneumatic line to open/close the jaws. You will need to arrange your own pneumatic valves / air source. There is a spigot which sticks out of the bottom of the chuck to hold part of it stationary while the remainder rotates. You need to fabricate a fork to receive this as you slide t...
