Aluminum Bellcrank

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.
