应用背景

滚珠丝杠和线性导轨是数控机床（CNC）、加工中心、精密测量设备、半导体设备的核心精密部件，直接决定机床的定位精度和运动平稳性。随着制造精度要求不断提高，对精密润滑脂的性能要求也越来越严苛。

润滑挑战

  • 高精度机床要求定位精度达到μm级，润滑脂的一致性至关重要
  • 低速高负载场合容易产生"爬行"现象，影响加工表面质量
  • 切削液、切屑会侵入导轨润滑区域，稀释或污染润滑脂
  • 精密丝杠不允许润滑脂过多，需要精确定量涂覆

Bettlube 解决方案

产品型号NLGI基础油粘度核心特性
BT-PMG0000号100 cSt超流动，适合集中润滑系统
BT-PMG00号150 cSt半流体，丝杠导轨通用
BT-PMG22号100 cSt标准型，通用精密脂
BT-PMG-HT2号68 cSt高速型，适合高速导轨

典型应用效果

  • 某精密模具厂五轴加工中心导轨，换用BT-PMG2后重复定位精度从±3μm改善至±0.5μm
  • 某半导体设备厂Y轴丝杠，使用BT-PMG-HT后低速爬行现象完全消除
  • 某汽车零部件厂CNC车床导轨，采用Bettlube精密脂后换脂周期从3个月延长至15个月
