Wow Lester, where did you find the MicroSpeed Electric Spindle, 600
watts, 8,000 to 24,000 rpm? Who makes it in Germany? Is it labeled
under other names, and what is the model number? Does the company
that makes the MicroSpeed make other medels? At 265 UK pounds, that
would be $492 US dollars. I have a few questions about the design.

Does it have pairs of angular contact bearings, configured for high
speed? Does it have a self adjusting bearing pre-load to compensate
for heat rise? What is the spindle run-out? Does it have a spindle
lock? What size collets does it come with? Does it have an air
cooling fan built in? Is it rated for continuous duty? As an example
the NSK Astro-E 250, at over $2,000 is a continuous duty device.

What a great find - it's a different price point, and if it doesn't
come with a range of small collets, then it is addressing a separate
market segment / applications, and compliments the Proxxon IB/E.

Thanks for the information, and God bless you.
