An aerospace client required multiple I.D. holes on a hinge, made of 4340 steel with a Rockwell hardness of 39 – 43. For this Level 2 Flight Safety part, we used our Sunnen honing machines & tooling to vertically hone three different-size holes. The customer also required a material microfinish of 16 and 63, meeting tolerances of + .0005″.
