Need help with a precision tube cutting process
Product is a two-layered tube less than one inch in outside diameter. Inner layer is titanium while outer layer is copper. Most of the tube is pressed together in our process except for about 2 inches at the ends. Customer wants the titanium to protrude from the copper at each end by less than one inch. One end of the tube's titanium protrusion length can be perfectly set but the other end cannot so we start out with an excess length of copper. Our process stretches the copper (to a varying degree) so cutting the copper in advance (prior to assembling the tubes) to a precise length in order for the finishing end of the tube to have the proper protrusion of the titanium after our process is not possible due to our process and material properties. Customer wants the copper cut after our assembly process in order to yield the desired amount of protrusion of the inner titanium tube at each end. [B]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?[/B]
Sorry to be somewhat vague on details but trying to avoid confidentially issues.
Thanks in advance for any help/suggestions.
