Re: Leader pneumatic air chuck replacement with manual chuck

Why would there be a clearance issue with the turret? Surely the turret would never pass over the chuck body. Besides, even with a smaller chuck you can open up the jaws to such an extent that it will be much bigger than 150 mm.

There’s only 5mm difference on the radius between 150mm (currently ...

Re: Leader pneumatic air chuck replacement with manual chuck

What is the largest manual chuck anyone has put on the Cyclone? The spec plate says 150mm max but that seems to be a non-standard size. So I've got the choice of either 125mm or 160mm. I would prefer the 160mm but would that cause a problem? I found out that the 200mm (~8") backplate is actually an ...

Re: Cyclone TU150U spindle power clarification

I spoke to KEB and asked them the maximum speed this motor is rated for and they said 3600 RPM. So why put 5000 RPM as the maximum on the machine when this is way over the spec of the motor?

I see there are 2 different motor specs for the Cyclone. There is the 2.2KW like mine:

Re: Cyclone TU150U spindle power clarification


Well @Jon777 if you don't beat me to it, I'll give this a go and feed back the results, or it may take me another 4 years to get there.... :lol:


@drumsticksplinter I see you did beat me to it. I've got a long way to go on mine as I only recently bought it. I've got my eye on a Yaskawa V1000 4KW ...

Re: Cyclone TU150U spindle power clarification


I would like to know what my VFD is set to, however I've never been able to find the PIN to access the settings.


That's interesting that you mention the need for a PIN to access the settings on the KEB F4 VFD. How do you know this as the KEBs as supplied by Denford come with neither a Display ...

Leader pneumatic air chuck replacement with manual chuck

I have a Denford Cyclone U fitted with a 130mm (~5") Leader pneumatic air chuck:

I would rather have a manual chuck so I want to replace this one (and sell it on). However I'm not sure how to remove it as there are so many bolt heads on its face as compared with a regular ...

Re: Cyclone TU150U spindle power clarification

That’s very interesting.

Here is a photo of the motor plate if anyone wants to see it:

You mention that they maintain constant torque to 3kW although on my machine plate it says 2.2kW. Does your machine have a higher rating?

I wonder if I would lose ...

Cyclone TU150U spindle power clarification

I just bought a 1997 Denford Cyclone TU150U which I’m going to convert to single phase. However I’m a little confused about the motor power as the different specifications don’t agree.

According to the side plate it is 3hp, 2.2 kW on 3-phase 415v with 5000 max rpm.

The KEB VFD for the spindle is 3 ...
