I recently acquired a Yuasa spindle speed multiplier with a straight shank. Woo! Hoo! The seller had said it had a 3/4 shank, and I already had a cou ple 3/4 Kwik 200 holders. Alas! As soon as I opened the box I knew the se ller didn't own a caliper.... or even a ruler. LOL.
I had to chase down a 1" holder for the Hurco, but now I have the ability t o turn upto 10,000 RPM. Knowing these speeders are hard to find, and new o nes are expensive I want to take care of it. There is nothing in the box r esembling documentation, so I was wondering about lubrication, bearing repl acement (if needed), other service, power handling capability, etc.
Anybody have good direct knowledge of these or even a manual they could sca n and forward? Be willing to share?
Thanks, Bob
