An Engineering Study of Automatic Bar Machine Maintenance and Repair Held at Concord Manufacturing Company,Michigan on 4May 1975,

摘要

The manufacturing processes at Concord Manufacturing Company are primarily involved with the operation of seventeen automatic bar machines. Many bearing failures and corrosion of copper and brass components were being experienced with all of the automatic bar machines. It was felt that the high cost of maintenance and loss of machine operation time should be reduced. This study was initiated to try to find a solution to the problem of machine failure,and consisted of three steps: (1) Records of equipment breakdown and repairs were reviewed and compared with those of other companies with similar equipment; (2) Failed components were examined to determine the cause of failure;and (3) Plant operations and facilities were analyzed to uncover any contributing reasons for the problem. Based on these findings,many contributing factors were uncovered and several recommended courses of action were suggested to solve the problem.
