客户挑战 / Challenge
某大型汽车发动机制造商凸轮轴分型线去毛刺依赖人工手持砂轮片打磨+钢丸抛丸，每班需要4名操作工，人工成本高且质量不稳定。分型线残留高度波动在0.05-0.3mm之间，超出0.15mm即判不合格。
A major automaker deburred camshaft parting lines manually with hand grinders + steel shot blasting, needing 4 operators per shift. Quality was inconsistent — parting line residual varied 0.05-0.3mm, anything over 0.15mm was rejected.
解决方案 / Solution
设计七头五工位自动去毛刺专机，四头圆盘刷阵列使用聚氨酯浸渍磨料刷盘（碳化硅#120）进行分型线强力去除，后接钢丝圆盘刷进行表面光整。机器人自动上下料，全程无人值守。
Designed a 7-head, 5-station automated machine with a 4-disc brush array using urethane-impregnated abrasive discs (SiC #120) for aggressive parting line removal, followed by wire disc brushes for surface finishing. Robot-loaded/unloaded, fully unattended.
实施效果 / Results
分型线残留高度稳定在0.05mm以下，远低于0.15mm公差要求。操作人员从4人/班降至0.5人（仅巡检）。单件加工成本降低68%，年产能提升40%。
Parting line residual stabilized below 0.05mm, well within the 0.15mm spec. Operators reduced from 4/shift to 0.5 (inspection only). Per-unit processing cost down 68%, annual capacity up 40%.
