Contribution to Reduce Defects in Production of Plain Bearings (original) (raw)

DAIDO METAL KOTOR AD (DMK) is a Japanese company dealing with production of plain bearings for vehicle engines. There are four highly productive automatized machining lines in DMK for bearings production. During production, some measures can deviate from the required ones. For this purpose, I have made a resolving concept, designed, had it made and tested a device-machine for checking bearings production and reached excellent results. The device is installed on the line consisting of: machine construction, electro-pneumatics, optical sensors, other sensors, PLC operation. After treatment, the bearing comes into device, it is checked, and if defected, it is rejected, the line is stopped and the operator searches the cause. This ensures quality of production, eliminates defected bearings, reduces costs, making customers more satisfied. Some of many high rating customers are: Honda, Volvo, Mercedes,..
