精密機械加工折柳盤甩油盤葉輪鎖母，CNC加工的歷史已經經歷了長達半個多世紀，NC數控系統也由最早的模擬信號電路控制發展為極其復雜的集成加工系統，編程方式也有手工發展成為智能化、強大的CAD/CAM集成系統。

Precision machining of folding discs, oil slingers, impellers, and locking nuts has a history of over half a century in CNC machining. NC numerical control systems have evolved from the earliest analog signal circuit control to extremely complex integrated machining systems, and programming methods have also evolved from manual to intelligent and powerful CAD/CAM integrated systems
