Guilloché Meets Roll Texturing
非遗视角：玑镂刻花与辊压纹理结合

玑镂（Guilloché）是 18 世纪成熟的机刻花纹技艺（日内瓦纹、巴黎钉纹），传统靠车床手持刻刀单件车制，日产仅数件。工作室可手工车出母版（节距 0.5 mm、深 0.12 mm），经电火花翻制成 φ40 mm 小辊，在黄铜表盘、首饰上辊压复刻，单件 20 秒、纹理一致性约 95%。辊压走带方向须与母版车削螺旋升角一致，否则网纹错位。
Guilloché—the engine-turned patterning (clous de Paris, Côtes de Genève) perfected on 18th-century lathes—is made one piece at a time by hand. A workshop can hand-turn a master (0.5 mm pitch, 0.12 mm deep), EDM it into a φ40 mm roller, and roll the pattern onto brass dials and jewellery at 20 s per piece with ~95% pattern consistency. Feed direction must match the master's helix angle or the cross-hatching misaligns. ---
