Laser Grooving for Inlay Pattern Preparation
激光开槽用于错金银图形预制

用 20–30 W 光纤激光在铜面开 V/U 形嵌槽（宽 0.15–0.5 mm、深 0.3–0.8 mm），CAD 图形直接导入，复杂纹样开槽效率为手工錾刻的 10 倍以上且槽宽一致，利于机嵌银丝。参数参考：频率 30–80 kHz、扫描速度 100–300 mm/s、同轴压缩空气吹渣；槽底熔渣须以 400 目油石轻磨清除，否则影响银丝咬合。激光热影响区约 0.05 mm，着色后不可见。该路线已用于乐器装饰件与批量文创产品的嵌银图形预制。
A 20–30 W fiber laser cuts V/U inlay grooves in copper (0.15–0.5 mm wide, 0.3–0.8 mm deep) straight from CAD drawings—over ten times faster than hand chasing with uniform groove width that suits machine-set silver wire. Typical parameters: 30–80 kHz, 100–300 mm/s, coaxial air blast; slag at the groove root must be lightly stoned off with 400 grit or wire seating suffers. The ~0.05 mm heat-affected zone disappears under coloring. The route now preps inlaid patterns on instrument fittings and production cultural goods.
