Long-term Care of Mandrels & Spinning Machines
旋压芯模与设备的长期保养

芯模是旋压工作室最贵的重复资产，保养分材质：木芯模存于相对湿度 45–55% 环境，远离热源防裂，表面蜡封补涂每季度一次；铝芯模氧化斑用 800 目水砂纸轻磨并重新抛光，存放前涂防锈油；钢芯模尾锥面每周涂二硫化钼锂基脂，防拉伤与锈死。设备侧：主轴皮带张力每季度检查，液压油 2000 小时更换，旋轮轴温升超过 40 °C 立即停机查轴承。建立芯模台账（累计旋压次数+修模记录）可延长寿命 30–50%。
Mandrels are a spinning studio's costliest reusable asset; care by material: wood chucks live at 45–55% relative humidity away from heat, re-waxed quarterly; aluminium mandrels get oxidation spots slicked with 800-grit wet-and-dry and re-polished, oiled before storage; steel mandrel tapers take molybdenum-disulfide lithium grease weekly against galling and seizure. Machine side: check belt tension quarterly, change hydraulic oil every 2,000 hours, stop immediately if a roller spindle runs over 40 °C above ambient. A chuck ledger (cumulative presses + rework log) extends life 30–50%.
