QA: Uneven Relief Depth
问答：辊压纹理深浅不均怎么办
标签：深浅不均,辊距,厚度公差,轴承
深浅不均多因辊距两端不一致或板材厚度公差大。先用塞尺校准辊缝左右差值≤0.01 mm，并改用同批次厚度公差±0.02 mm 内的板材。若仍不均，检查辊轴轴承是否磨损导致挠度。局部过深可减薄该区辊距补偿。
Uneven depth usually comes from uneven roller gap or sheet thickness variation. Calibrate the gap with feeler gauges so left-right difference ≤0.01 mm, and use sheet within ±0.02 mm thickness tolerance. If uneven still, inspect bearing wear causing roller deflection. Compensate local over-depth by reducing gap there. ---
