Surface Integregity Testing for Aero update

Hello everyone!  I want to provide an update of where Makino is with surface integrity testing for aerospace.  Since the last webinar in January 2008, we have added Inconel 718 alloy to the testing, and have also added sinker test results for all alloys tested so far.  These include 6061-T6 aluminum, 718 alloy Inconel, 17-4PH stainless, and 6Al-4V titanium.  These materials were machined with wire EDM, using brass and coated wires with one, two, and three pass machining.  Sinker EDM tests were done with a widely recognized, premium grade of EDM graphite to rough, semi-finish, and finish states. 

The test results on all alloys have been very impressive.  If you would like a free copy of all three lab test reports, please email me, and I will be happy to send electronic versions for review.  Also, if anyone would like to work with Makino on more specific tests (materials, geometries, coupons, or additional testing such as tensile strength after EDM) contact me to set things up.  I can be reached at  jeff.kiszonas@makino.com  or 248-232-6208.
