近年来随着国内制造业的产业升级，机床用户对数控机床的需求不再是过去简单的产品加工，越来越多的用户开始对机床的切削能力、加工精度、效率以及复杂曲面处理能力等方面提出了更高的要求。为了满足上述客户需求，除了更出色的系统控制性能，还需要强大的电机作保障。所以本期小编推荐一篇关于如何维护主轴电机，才能保证其具有更持久的生命力的文章，敬请参考。
主轴电机的磨合
由于轴承内有高速油脂，在运输过程中或长时间不使用，油脂状态会改变，通过磨合使油脂纤维沿轴承运转方向顺序排列，可以降低发热，并使轴承得到较好的润滑，从而使主轴电机正常运转。如果不磨合直接高速启动，由于润滑条件不好，就会产生噪音、刺耳的尖叫声、发热等现象，甚至会损伤轴承，降低使用寿命。
当电机、维修后的电机开始使用时，或电机使用中出现扎刀的问题时，或停机两天以上的时间重新使用时，必须进行磨合工作！
主轴电机的磨合实际是非常讲究的，下面是一套主轴电机磨合的基本程序：
1)磨合之前必须清洗压帽、卡头和转子。
2)磨合时可以不装压帽，如果装压帽一定要装卡刀具到位。
3)低速延时缓慢启动。
4)检查电机旋转方向，磨合时必须保证顺时针旋转。
5)从主轴电机允许的转速空载运行30分钟，如果是扎刀磨合时间要延续到一个小时。
6)按照2000转为级差进数，每一档转速磨合10-15分钟。
7)达到速时运转20-30分钟。
8)在确认每一档转速下主轴电机运行正常、平稳，没有刺耳的尖叫声、没有不规则的振动、温升正常、电机温度稳定的情况下才能进行下一档的磨合。
主轴电机的预热
主轴电机预热是保证电机轴系能有一个良好的工作精度，这是每天开机时都要做的工作！请记住：高速电机在预热得情况下开始工作才能保证良好的工作精度！下面以额定功率上限速度为10000rpm的主轴电机举例，列出常用主轴电机的具体的预热工作程序，请大家在实际中参照不同型号电机的不同转速参数值，从低速开始按照2000转为级差进数进行预热。
预热电机时注意：装卡刀具之前一定要清洗压帽、卡头和转子，并将刀具装卡到位。
