Steel Piston Shock Strut

CT Hone, Inc. precision I.D. honed this piston shock strut with an inside diameter of 3.000" for an aerospace client.  We used our custom long/horizontal honing machine & Sunnen tooling.  The piston shock strut, made of 4140 steel, with Rockwell hardness of 43 - 46, met tolerances of ± .001" and had a microfinish of 16.  We worked from a customer supplied operation sheet and 2D CAD drawing to meet our customer's specifications.
