Need help with a precision tube cutting process

Hi,

Is there a high-precision process which we could use to cut the copper from the finish end of the tube while leaving the titanium tube underneath undamaged?
Sorry to be somewhat vague on details but trying to avoid confidentially issue.

Please help.

Thanks!

I didn’t find the right solution from the Internet.
