3M Co. subsidiary Ceradyne Inc. will trim 93 workers at its plant in Lexington, Ky., according to a filing with the Kentucky Office of Employment and Training.

St. Paul, Minn.-based 3M acquired Ceradyne late last year for $860 million and has folded the Costa Mesa-based company into its advanced-ceramics business.

Ceradyne’s plant in Lexington, which opened in 2004, makes body armor components. It will remain in operations, according to 3M, which did not disclose total employment at the Lexington plant. The company indicated the cuts are a result of reduced funding from the U.S. Department of Defense as part of federal across-the-board budget cuts that took place March 1.
