Good morning Everyone:
I posted in a recent thread, about how reluctant I've become to re-fill the coolant tank on my VMC, now that I've moved into a much smaller shop than my previous digs.
So I went on the net and found Unist, a company who makes a MQL system you can put onto your machine with a magnet to hold it on, so you no longer have to deal with the skanky, smelly mess of water based flood coolants.
Yesterday was the first time I ran a titanium (Ti6Al4V) part using the system.
I crapped my panties a bit and clutched the big Class D fire extinguisher close to my chest before I pushed the green button.
Obviously I was freaked about lighting the mill on fire.
I'd been reading on the internet about how you CANNOT mill titanium without massive flood coolant and how it will all be a BIG FUCKUP if you try.
Well, it ran like a bunny; no problems at all.
I stopped midway and felt the part...totally cool to the touch.
That was using a thrasher cutter too...I was too cheap to put in a new one until the old one was truly dead.
Granted I was using high feed milling (adaptive roughing with HSMWorks) so a big DOC (0.400) and a tiny stepover (0.0075") but it whistled along at 80 IPM and 3600 RPM, no burps no farts no nothing!
This is with a bog standard 5/16 4 flute TiAlN Garr endmill with a 0.020" bullnose in a vintage 2001 Haas Minimill.
I don't know how hard I could have pushed it but my fixturing is pretty wimpy (three 8:32 screws with 0.075" engagement holding a part spigoted into a fixture plate by 0.075" and sticking up about an inch), so I chickened out about making it work harder. (it's a high value part and I'd hate to lose one through Speed Greed)
This is an unexpected surprise...I didn't think it would go so well.
Just thought I'd let everyone know.
Also any comments others might have, I'd love to hear!
Here's a picture (yes it's part of another another freaky sex toy).
It's just roughed at this stage but the inside is already finish milled.
Came out very nice...better than I was used to seeing with Blaser.
Cheers
