Hiya,

Its an upgrade to what your machine will come with that's for sure, the only thing I would consider is that it has an ER11 size collet.

Although thinking about it more and giving the overall strength of such machine consideration, ER11 is probably about the right limit to place on it...

...a machine like this really isn't designed to cope well with any kind of substantial machining.

Bigger Tooling = Bigger Forces

Cheers lee, this machine is pretty much only going to be used for engraving fibreglass and plastics, not sure how well it will cope with that?

The motor you linked to is air cooled and very noisy the water cooled one's are very quiet. You will also need a VFD to power it.

The one he linked to is not going to work anyway because his machine is just not made for these large spindles. Also, in regard of noise, I must say I disagree that it matters. I have a similar spindle, and while it may be noisier than a water cooled one, it is MUCH quieter than the one he has at the same RPM. I had a similar DC motor like he has and I know this for fact. Also, once the spindle starts cutting the cutting noise is several times more than the spindle noise. Not to mention the vac... :)

So, air cooled vs. water cooled... water cooled wins by miles when you cut air, but when you use it for cutting it makes no real difference at all.

Cheers lads some good info there, hoping to have it connected to a pc this evening, like I say im mainly using it for engraving plastic and fibreglass sheets. What is a vfd? I have seen a few spindles for sale which have some sort of pcb stating mach 3 controlled or something to that description

I just bought a 2.2kw spindle and it arrived today I fitted it into the spindle mount (80mm you would need to buy new spindle mount and modify your machine to fit) and then weighed them both and it weighed 6.5kg's I would think that a 1.5kw would be far too heavy for your machine.

It's making me rethink my gantry and I have a lot chunkier aluminium than yours has in the first place.

I would go with the 500w spindle linked earlier if I were you as it seems more in range what your machine can handle and a drop in replacement.

cheers desertboy, my head is in the shed now lol not sure which to buy

[ravihotwok]

is this a good compromise?

Yes, that's MUCH better. It is the one I am using today, but beware, it needs a VFD and the Z on your machine is not made for this type of heavy and large spindles.
