Spindle for sable 2015

[richie00boy]

I use my small machine mainly for PCBs. It came with a spindle basically the same as your 400w Chinese spindle. I get 40 microns runout and it is OK for PCBs. I do SMT, but not the really tiny pitch stuff. It will cope with sheet alloy too. The downside is it's speed of 8000RPM means that you can't run the machine all that fast.

CNC on a budget spindle. This looks very similar to the Wolfgang spindle which is supposed to hit about 20000RPM. I bought one of those before I got my machine. They are very accurate, but I have heard they are only any good for isolation milling not actual cutting out of PCBs, so I never bothered trying mine. Perhaps I should!

The SPD-ER11 looks similar, but only 10000RPM.

Lastly, I've also got a 0.8kW water cooled spindle. It's great, but I haven't dared to mount it on my machine as it weighs 3kg and with the leverage due to the amount the spindle hangs off the rails I think it's too much for my little machine. So I haven't bought the VFD for it yet.

So despite me buying two other high spec spindles I'm still making PCBs using the cheap spindle that came with my machine.
