                                                    數控機床系統的維護
                                                    作者:    發布于:2016-01-31 16:55:49    文字:【】【】【
                                                    數控機床系統的維護:
                                                      
                                                      (1)嚴格遵守操作規程和日常維護制度
                                                      
                                                      (2)應盡量少開數控柜和強電柜的門在機加工車間的空氣中一般都會有油霧、灰塵甚至金屬粉末,一旦它們落在數控系統內的電路板或電子器件上,容易引起元器件間絕緣電阻下降,甚至導致元器件及電路板損壞。有的用戶在夏天為了使數控系統能超負荷長期工作,采取打開數控柜的門來散熱,這是一種極不可取的方法,其最終導致數控系統的加速損壞。
                                                      
                                                      (3)定時清掃數控柜的散熱通風系統應檢查數控柜上的各個冷卻風扇工作是否正常。每半年或每季度檢查一次風道過濾器是否有堵塞現象,若過濾網上灰塵積聚過多,不及時清理,會引起數控柜內溫度過高。
                                                      
                                                      (4)數控系統的輸入/輸出裝置的定期維護
                                                      
                                                      (5)直流電動機電刷的定期檢查和更換直流電動機電刷的過渡磨損,會影響電動機的性能,甚至造成電動機的損壞。為此,應對電動機電刷進行定期檢查和更換。數控車床、數控銑床、加工中心等,應每年檢查一次。
                                                      
                                                      (6)定期更換存儲用電池一般數控系統內對CMOSRAM存儲器件設有可充電池維護電路,以保證系統不同電器件能保持其存儲器的內容。在一般情況下,即便尚未失效,也應每年更換一次,以確保系統正常工作。電池的更換應在數控系統供電狀態下進行,以防更換時RAM內信息丟失。
                                                      
                                                      (7)備用電路板的維護備用的印制電路板長期不用時,應定期裝到數控系統中通電運行一段時間,以防損壞。
