I’m starting to machine Titanium on my Small X3 CNC milling machine. In this video I show some of the end mills I’m going to try and my first cuts in 6AL-4V.

Maybe I missed it but did you say your spindle speeds ?
Hearing people say quarter inch irks me. Metric is better
What model mill?
Hi Jim great video , I have been researching titanium just a little , and I was wondering if I could get your thoughts on something , I and getting into Paramotoring ( PPG, or Powered ParaGliding ) as a hobby , I know it will be expensive but eventually I would like to have a 2stroke engine case, crank , rod , cam and piston Machined out of titanium , (10k???? or so) would this be a good idea? the problem with cast aluminum is the heat and parts wear and or fatigue, for every 25 hours or so the engine has to be taken apart and inspected then rebuilt…….
I'm looking to build DIY CNC machine for titanium and I wanted to know if you need any special cnc machine parts?
Do you have any recommendations for trying to do simpler cuts with hand feed? I have an X3 as well.
do you have any problem when machining titanium ? if you do , contact me at whatsapp: + 86 18091695160. we supply the best titanium material .
The best metal!
What stepper motor driver are you using? What kind of connection to the computer?
Is it possible to make engine parts like this?
how much was the block?
Awesome vid Jim! I'm really glad to see you could apply some of the info from my videos. Looks like you're rockin the titanium.
What is the cost of this set up in total please, IE the machine and CNC had a package.
Thanks
are those the same carbide bits used on routers for wood working?
What DOC would you use for creating a pocket?
Did you mean 0.025" DOC – depth of cut? Or ~ 0.6mm.
Great! Hope you enjoy the X2 CNC. I highly recommend looking at high speed machining techniques. In my opinion it's the only real way to machine titanium on a small machine. I've been moving over to BOBCAM which seems like it's probably the least expensive true 3D high speed machining capable CAM package.
awesome i just got a x2 machine im in the process of cnc-ing out im a knife maker and im hoping it will work decent enough on some .187'' thick 6AL4v Ti i have for frame lock folding knife .enjoyed this video and gives me hope i can do it with mine-with a million slow passes of coarse haha
I got my X3 to be so quiet by turning the volume down in the video editing software 🙂
I have an x3 and your machine sounds sooooo quiet. How did you get it to be so quiet?
Thanks for the tip, I'll try that next time.
To get it to focus you have to put your hand or a piece of paper or something to get to focus at the closer object.
What kind of cuts can you make on the G0704? It seems to be a good bit stiffer than the X3.
I bought the piece of 6AL-4V as a cut-off for a little over $300.00. Expensive for me, but less than equivalent cut to order pieces. I should be able to make 2 lowers out of it, if I don't mess one up. Still, I'm going to take my time and try to not make any mistakes.
I thought about doing the flood cooling thing, but most manufacturers don't recommend it with high speed machining techniques and AlTin coatings. Since I'm at the limit of my machines rigidity and the tool is still barely warm, I don't think flood would do me much good. A good airblast to clear the chips on the other hand, would really help I think.
