WHY would you use a diamond wheel for a HSS???
WHY would a "cobalt drill" be so special?
What about "Titanium Drills"?
Titanium is stronger than steel, right?

Ya hey der (Minnisota/Wisconson) its tic tin coating two tenths
tick :-) don't ya know. Gotta love those cheese heads, fer kri yi
Yes titanium is good shit menard, one of the $strongest$, $easy$ to
machine soft metals that I have come across. It is not used to make
cutting tools, its soft & can't be hardend, to the best of my
knowlege, maybe gas or liquid nitrided? Hmm have to check into that.
Gotta alot of scrap Ti to make shit out of...........
The Ti claim on cutting tools is a coating.
Usually that gold stuff. All it really does is make a *slipery*
surface to help with chip ejection. ie when drill/milling say cast AL,
(the worst) the chips stick/weld themself to the cutting tool.
Basterds!<g> Fucked up way to many holes ect not being carfull w/o
coolent on finish passes or going to deep on last plunge/ream. Thank
god for ball bearings to bullshit close up loose dowel holes. Good
machinists can *hide* their mistakes or make a new one in 1/2 the
time.

Search for Titanium 80 to 100% ....
The Ti-6-4 alloys are sometimes used.

This one in this state is Rc 39.

Yes 6Al4 used in ultrasonic apps. It has a grain structure that has to
be oriented correctly when machining sonotrodes so it vibrates in the
right direction at 15,20,30,35,40 kHz.
Some think its tough to machine? Well compareed to some mold tool
steels, its a piece of cake. Nice finishes, I dont even use coolent on
a manual lathe. The other guys just look at me with the "deer in the
headlight look" Ive used about 1 new CNMG tool bit now in about
6months! Oh maybe 2, I cracked one when I thru the piece out of the
chuck. It got to the end of the cut & was taking about a 5mm cut due
to runout. Slow RPM, I was about 5ft away. when it happened. Hehehe,
damn 3"dia piece went rolling across the floor alomost hit the boss in
the foot.<g>
The chips aren't even that sharp! My hands are nice now, the ladies
like it :-)
Drilling deep holes & taping are a bitch. It heats up & expands whilst
taping, thus seizing the tap. Cant use coolent only *special*
cutting oil/or paste & good quality taps.
Another materiel used in sono's is CPM. Now that shit is crap to cut.
bye bye all cutting tool edges, nice knowing ya. Never get a nice
finish, chips turn into like concrete when the coolent dries. It is
powdered metal, what do you expect? Plugs up chip conveyor/augers real
nice if left in there too long.

Does this not depend on the shop owners priorities? Where I last worked
they hired me for this skill only. Many shops I have been in need someone
full time to "manipulate some obscure CAD/CAM program".
Actually I feel many shops can benefit from someone full time to automate
the CAD/CAM
program....whether it is obscure or not.
Just curious. What do you consider the "most important job skill for a
machinist".
Hope it's not agreeing with the status quo and fitting in so everything
runs smooth.

Anybody with a brain would keep drills sharpened in case you
ever need to drill a hole ... and keeping them sharp is
usually cheaper overall too.

Interesting. Why a Ti alloy?
Why oriented?
What grain structure? Annealed?
Tell us more.

cncmillgil
it has excellent acoustical properties, does not rust, can be used in
medical/food applications. A cheaper route when prototyping is to use
6061Al.
Hardened apps go with CPM.
> Why oriented?
Due to the way alot of steel/Al is made, rolled, it produces a grain
direction. When ultrasonics are applied, it vibrates in the grain
direction, So not oriented properly, a sonotrode(ultrasonic welding
horn) would vibrate, lets say, horizontal instead of vertical. Not
producing a good weld on the parts being joined.
> What grain structure? Annealed?
> Tell us more.
Thats about it for ultrasonics 101. See
The Recognized Technology Leader in Ultrasonic Plastic Welding:
http://www.herrmannultrasonics.com/
I've worked at Dukane & with Branson. IMO Herrmann is the "Ferrari" of
ultrasonics.
FYI: they have 10 apps in the new Mercedes E class.
