The facility performs precision machine-shop work on a job shop basis. The process begins with cutting the stock to size, machining and hand deburring the parts. Next, the parts are machine deburred in a large tumbler washed, degreased, shipped offsite for chromating, and returned, assembled, inspected packaged, and shipped. The team's report, detailing findings and recommendations indicated that the majority of waste was generated by the deburrer rinse but that the greatest savings could be obtained by replacing the cutting fluid concentrate, thereby eliminating the need for degreasing with 1,1,1-trichloroethane. 收起
