某手风琴厂需在大面积 0.6 mm H62 黄铜板上压出细密菱形纹以调节声学阻尼。采用双辊连续压花，花纹深 0.05 mm、辊速 5 m/min，压后板面平整度≤0.1 mm/m。成品共振频率更均匀，音色稳定性提升约 12%。
An accordion maker needed fine diamond relief on 0.6 mm H62 brass to tune acoustic damping. Using twin-roll continuous embossing at 0.05 mm depth, 5 m/min, flatness ≤0.1 mm/m was held. Result: more uniform resonance and ~12% steadier tone. ---
