3040Z machine spindle upgrade/modification

[enterpryse]

Hello,

I am on the verge of buying one of these machines too, but as far as I can tell the motor doesn't look too great (looking at machines with 230W motors). I almost purchased the machine when I realized that the spindle mount looks integral to the Z axis. I am a complete mechanical engineering noob. Would you mind breifly expanding on how you would go about buying/creating a mount for a bigger motor (65mm or 80mm)?

Also, I don't suppose that you/anyone here knows whether the extra weight of a bigger spindle (2KG extra for 0.8KW, 4.5KG for 1.5KW and 7KG for a 2.2KW), would be too much of a problem? I'm very new to all of this.
Sorry if I've hijacked the thread (seems to be along the lines of what the op was asking though).

Thanks,
Tom

I'll send you a picture of the supplied clamp that I'm having machined. I think the original is 52mm. I too am a noob at this but if there is a lesson for me to take away from this it's this issue with the clamp and the carrier.

I personally got a bare bones type of thing and upgraded various bits like the spindle, motor etc etc. My spindle is 400W, I wanted a 1.5KW version but the cost of that and the power supply and the hassle of changing out the mount I just compromised.

Cheers

A picture of the mount would be greatly appreciated, thanks! I've been researching this for about a month, the spindle mount seems like the last hurdle before purchase, but I'm not sure how easy it's going to be to fix.
You say you're going to compromise on the motor, does that mean stick with the 400w or only upgrade to something like 800w?
I can't figure out the message system on this site, if you are able to then send me a message, I'll send you my email and you can send me the mount picture if that's still okay with you. Or just post the mount picture on the forum if you're okay with that. Either way would be a massive help :)

Many thanks,
Tom

TBH modifying the carrier so it's possible to mount alternative spindles has been quite a problem and am in the process of having it done by a machine shop.

The compromise I'm making is that I am settling for a 400W brushless motor (I don't like brushes LOL). I would have liked a more powerful alternative but the cost for that and a suitable controller means I'll have to wait a while. But when the bracketry has been modified it will be an easy upgrade..

I will send a picture as soon as I get it back from the machine shop.

Cheers

Hi Stuart
I have recently purchased a 3020T machine. I have now realised that the one piece Z axis mount is a serious obstacle to my upgrading the spindle from the current 300W spindle supplied with the machine. I was wondering what progress you have managed in obtaining and mounting your new mount (assuming that you went ahead with this).
Thanks
