An aerospace customer approached CT Hone, Inc. to I.D. hone an AMS 4201 aluminum Bellcrank. To hone the .900″ thick, 5.975″ long and 3.951″ Bellcrank we used Sunnen honing machines & tooling. While honing several holes in the Bellcrank, we achieved a tolerance of ± .0001″ and true position of .007″. The I.D. of the final holes measured .8122″, .7770″ and .6872″ and a microfinish of 32.
