Durability of a 6040 ?

[jimbo_cnc]

I've read that they won't last etc, but how long will they last?

If I want to make an item from Nylon, which involves cutting a 64mm x 64mm block from 16mm sheet and removing 15cm3 from the inside.

How many will it make ?

If it makes a 1000 it will have paid for itself.

High Chance it will do that and much more if you spread the production out but no one can say for certain you won't have issues or how long before you do. I've seen some work fine without any problems and I've seen some give up the ghost within the week.!! . . .Here in lies the problem.!!!

For it to work thou you'll need to buy one with a decent spindle like the water cooled/vfd setups, the poxy little DC spindles that come on the cheaper ones won't be any good.

Thanks, I'm itching to get making things, and I have a plan.

I think a little 3040 will do me to make the my plastic bits I'm interested in. I'll see if better spindles are available but I might just get a cheap one and then get a water cooled replacement ready for when it dies.

This way I can get into the hobby quickly while I design a better and bigger machine or two :)

Will be searching eBay now, if anyone has suggestions let me know. I won't hit the buy button until at least Sunday.

Wouldn't do that or buy the spindle at same time because those brushed spindles are Crap and will fry within the weeked if pushed hard. BUT Then you also have other issues like mounting the spindle and running the cables. Those cheap 3020 machine with poxy spindles have no spare room in the energy chains for water pipes etc but worse the Z axis is often not designed to take the heavier spindle and you will have problems.

Worst thing you can do is go rushing in so just hold off the "buy it now" button and do some more reasearch. What's your budget.?

Well, I was very happy with £480 for 3040 (not 3020) when I thought that would do what I wanted.

£180 for water spindle and VFD is OK too, as that will carry over to my next machine I assume? although it doesn't seem to include pipes/pump/etc.

Post the link because if it's the one I'm thinking then wouldn't buy that.!
