DIY ATC Spindle

[Husky1]

that might be true, but even if the springs fail, it is much much cheaper to repair the damage than buying 3k+ spindle. At the end of the day, this is still home made cnc, not proffesional cnc so i hope it will do the job.

10krpm spindles are closer to 1k.
All you'd need to do is use a larger tube & bearings to accommodate adequate components, why would you not?

i want 15krpm+ spindle with atc and must fit my z axis configuration. Got made mine for almost half the price.

I like your approach. I am willing to help with calculations and design. All you have to do is point me at the desired components and define your space constraints

Hi Husky
Hi Irving (I sent you an email Irving)

Gee Husky sounds like you are on the right track to me. Belleville washers do fail after millions of operations, a common service repair for spindles in commercial use. For home use they should last a lifetime. And making something is always more satisfying than off the peg.

Im looking to do something similar. I'd be interested to see more details on the spindle size and bearing arrangement.

Is it a squeeze release or does it load the bearings when pressurised.?

Is the spindle hardened and ground?
