山东科技大学继续教育学院毕业论文数控车床的典型故障分析与维护维修分析院（系）山东科技大学继续教育学院专业矿山机电年级2009级学生姓名周晴指导教师张纪良二○一一年十月十九号摘要：电子技术的发展以及国内数控装置的发展使得数控装置的价格走低,特别是经济型数控车系统的价格已经是到达了它的最低点。经济型数控车床在中国的机械加工行业中得到了迅速普及,使得我国机械加工水平无论在加工质量方面还是在加工效率方面也得到了迅速提高。但是随着机床使用时间的延长,数控机床会出现这样或那样的故障,本文就以经济型数控机床的常见故障为例,谈了一些解决的办法。关键词：数控车床故障检查法典型故障维修维护Abstract:ThedevelopmentofelectronictechnologyandthedomesticdevelopmentofnumericalcontroldeviceNCdevicemakesthepricelower,inparticulareconomicsystem,thepriceofNCalreadyreacheditslowestpoint.EconomicalCNClathemachiningindustryinChinahasbeenrapidlyinpopularity,sothelevelofmachiningqualityintermsofprocessingorinprocessingefficiencyhasalsobeenrisingrapidly.Butastimemachinetool,CNCmachinetoolswillbethefaultonewayoranother,thistypeofCNCmachinetoolstotheeconomiccommonfaults,forexample,talkedaboutsomesolutions.Keywords:CNClathefailuretestforfaultrepairandmaintenanceoftypical.目录一、数控机床......................................................................................................................................11.数控加工的概念....................................................................................................................12.数控机床的特点....................................................................................................................13.数控机床使用中应注意的事项............................................................................................2二、故障检查方法..............................................................................................................................3１．直观法..................................................................................................................................3２．自诊断功能法......................................................................................................................4３．功能程序测试法..................................................................................................................4４．交换法..................................................................................................................................4５．转移法..................................................................................................................................5６．参数检查法..........................................................................................................................5７．测量比较法..........................................................................................................................5８．敲击法..................................................................................................................................6９．局部升温..............................................................................................................................6三、典型故障......................................................................................................................................71、换刀装置故障.........................................................................................................
