Nema17 motors driving 1204 ballscrews ...that ok?

[HankMcSpank]

That spindle assembly looks really good and excellent value. I can't comment about the noise as I can't hear it!!!(only the cleaner). G.

Ironically, having just bought asbo's 300W spindle (which is a surprisingly fine spindle type for the price) ....the one I've now just gone and bought afterwards (above) looks to have exactly the same driving motor on it - they are just gearing up the motor's RPM with the pulley (I note they quote the motor at 24V vs. "upto 48V" that the 300W spindle motor is normally spec'ed for - I guess the spindle that the motor is driving only has modest bearings & wouldn't cope well with RPM above 10,000RPM - actually, perversely, I'm hoping the spindle *doesn't* use ceramic bearings & therefore the spindle shaft might be groundable - is that a word?)

Re the noise...as someone who mainly mills PCBs, I'm a sucker for a quiet spindle, and yes it's very quiet, which is why I pulled the trigger so quickly (the seller had sold 4 & only had one left)...only last week, I was comtemplating water cooled spindles, but I'm pleased I didn't now...I really don't need the extra grunt (& complexity/weight) that it yields.

Is there space between the linear bearings? could always make a new block up so as not to ruin the existing.

It's all too easy to reason that most members on here are of a solid engineering background ilk...I'm not - really small children laugh loudly at my output (I often hear them muttering things like "FFS, that bloke should have used angular contact bearings on his Z axis"...I have no idea what they're going on about).

I'm a reluctaant CNC'er ...I potter along blindly, then hit a problem ...& spend way too long trying to find an inadequate solution! (whereas, I'd much rather be playing my guitar & gulping on a cool one)
