I have been thinking about a micro machine build, and I stumbled across this on eBay: NSK Nakanishi NR-303 Ultra High Speed Spindle 30,000 rpm - Standard Size Chuck | eBay I was wondering how often these things show up on ebay. Not NSK specifically, but rather just quality high speed spindles in general with less than 2 microns of runout. I am not nearly ready to buy yet, but I have been fretting over spindle sourcing for awhile and this seems like a good deal. |

but I thought I'd just point out that that's not a complete spindle assembly. It would need a control unit, for one thing. You don't want to know how much those cost - just to give you a hint, that site they refer you to for more info wants $271 for one collet (which is also not supplied with that unit listed.)

| Given that they come with no VFD or collets, and that they are described as "unsure if they are new or used", by the look of them they certainly look far from new, and may not have the spec of 2 microns now? It may be well worth it as I don't know what these run for brand new, but it seems a lot to me for what appears to be an incomplete "pull"? cheers, Ian
