Ken,

Now you're talking a language I know, other than SHP Chevy's.

Nice finish on the part ( from what I could see ).
What feeds & speeds are you running on the first cutter?
How much stock per pass were you taking off? Were you
running air/oil mist, or just cold air to cool the tools?

You'll probably find this interesting. I just finished a
multi-year development project with a client for ultra
high detail - high speed machining in tool steel. We
just purchased six 3-axis high speed milling machines
for this project at well over $2,000,000.00

We'll be running in the 30,000 - 40,000 rpm range with
cutters down to 0.006 diameter. Yes, that's two times the
diameter of a human hair. Get this - run time for these
cutters is anywhere from 20 - 30 hours. What are we cutting?
All future US coin dies at the US Mint.

I'd love to be able to post an video of that process, but
then I'd be conversing to you guys from behind vertical bars.

Pretty Cool Ken, that is very nice . Looks like it's time to paint the cabinet again . I worked for Wolverine tube years ago and if you had more than 5 minutes down time someone was handing you a gallon of paint and a brush... Never saw so much green paint in my life... I think some of the machines had 6 inches of paint on them .

I'll bet that the router bits are quite expensive...we used to use the same type of machines to route out the circuit boards at the facility that I worked at...

The vid looks good. Can't believe those cutters go thru 60Rc like that and throw real chips. Looks good so long as the numbers are there. Had a Bostomatic at my fingertips and did some hard milling in the past but the chips were usually dust. Since I have been working where I've been working, I have been designing a lot of parts that require wire work. The parts lend themselves to that process and they encourage it. You gotta wire dere on da nort side??

It really is a nice,clean,cutting edge professional shop up der.
The machinists know their stuff and the boss,Paulette, keeps everyone on their toes.

I love to watch stuff like that. I drive my wife crazy waching "How Things are Made" and "How Did they Do That".

Spindle 1650 RPM , Feed 40 Inches per Minute,
Depth of Cut .010 Deep........... Length of cut 1.5"
Modern Technology.....Crazy........It's the Coatings that have been developed that are the Key to this Magic.....these tools have two coatings on them, without the second coating they would fail......Here is how it was explained to me.......The second coating is put on in a thickness relative to the Empire State Building being 1MM (.040) high, the coating thickness would be like a Dime laying on the sidewalk in front of it.......The Crazy thing is that almost all the heat leaves with the chip, after machining the part is just mildly warm to the touch.....The Cutter cost about $175, and we did about 60 pcs with absolutely no change in size.......we had to hold +/- .0002 which was no problem........Can't deviate from the manufacturer's Speeds and Feeds....the first time we ran this part this way , as the Tool comes into the part you just stand back and wait for the crash because it go's against everything we have learned in the Past....Pretty Cool.......We ran with just air blowing on the Cutter to clear the Chips

Very cool! Thanks for the info...

Oh yeah,I'm in QC... Now I get to watch machines run as I eat my lunch....Thanks!
