四.主轴轴承

采用国际知名厂牌P4A及混合陶瓷球角按触轴承。采用KLUBR NBU15油脂润滑。

五.主轴电机

采用高品质符合有色合属材料及独有的腔封处理；
六.组装

组装区采用空调控制温度，精确选配零件公差配合。采用进口轴承加热器加热轴承，无过热及残留磁性隐患。组装步骤均标准程序校正。
锁紧螺母均依标准值以扭力扳手锁紧，井坚持不以调整螺母校正主轴。出厂主轴直径在150mm及以下的，偏差均达到0.0015mm以内。主轴直径170mm以上的，偏差均达到0.002mm以内。
采用进口电主轴专用测试设备，精确检测每根主轴的功率、振动，噪音，温升旋转精度。

七.主轴的平衡测试

使用CEMB电脑平衡校正机，精确检验主轴平衡，井提供检验记录。检验主轴平衡已达到IS01940标准的G1等吸。

八.主轴的胞合测试

采用电脑控制的全自动跑合程序，提供温升过热保护剂完整温升记录。跑合程序可依据主轴转速及特性设定运转测试时间，保护温应从而保护轴承。出厂主轴均经完整跑合程序，可以缩短用户上机的跑合时间，减少机床组装时间。
