Micro drilling help needed
My research and information from drill bit and autofeeding drill vendors are yielding conflicting information regarding necessary drill speed (RPM) and feed rate for my application. I need to determine the time required to drill through .090 inch thick Inconel 625 using a .028 inch DIA drill bit. Time needs to be ~3 seconds or less in order for my process to be feasible for production.
Can this be done with an automatic feeding drill assuming rigid mounting of both workpiece and drill?
Appreciate any response from someone well versed in drilling tiny holes in very hard metals(2205, 2507, Inconel 625).
Thanks
