saw this on Instagram, a two thou end mill!
and do you do conventional or climb milling with it.......I get nervous using 1mm milling cutters
Kearns can really hog metal off so maybe ceramic?That is cool. I wonder what cutting RPM they used, and how on earth they kept that cutting with no runout. Must have been an air bearing spindle and about 50k rpm I guess.
Actually I’ll just ask them!That is cool. I wonder what cutting RPM they used, and how on earth they kept that cutting with no runout. Must have been an air bearing spindle and about 50k rpm I guess.
I've heard a story of something similar, one company gave a tiny drill bit to another so they EDMd a hole down the length of it and gave it back.I remember my father telling me about an engineering show he was at, 1950s I think. A German exhibitor was boasting to his British rival how much better the Germans were and gave him a very small drill bit to show their superiority. At the next show the British boss gave it back to the German and told him to unscrew the end and then tipped out three more.
I would 1000% smash that endmill on first cut.

That was Lockheed who sent Marconi avionics in basildon a drill bit thinking they was clever.I've heard a story of something similar, one company gave a tiny drill bit to another so they EDMd a hole down the length of it and gave it back.
But would they know what Basildon Bond is let alone put a pen to it.I not sure anyone in basildon can read
Two thou is like a very fine hair, right?
I'd put it down once and it'd be lost forever!

Forty years on the site is warehouses and I not sure anyone in basildon can read
I got a reply, spindle speed is up to 70000rpm!!That is cool. I wonder what cutting RPM they used, and how on earth they kept that cutting with no runout. Must have been an air bearing spindle and about 50k rpm I guess.
