镀铬辊面(镀层 15–25 μm)保养要点:辊面残蜡与油污用 60 °C 中性皂液软布清理,严禁钢丝球与硬物刮擦划伤;辊面轻微划痕可用 2000 目油石顺轴向修整。镀铬层磨损后可退镀重镀 2–3 次,每次重镀须重磨辊形。机械侧:两端轴承每季度补高温锂基脂;装辊后打表检查辊颈跳动 ≤0.01 mm,超差会周期性压深不一致。停机超过一周时辊面离板存放并涂防锈油,木箱内加防潮剂,辊与辊之间软垫隔开。

Caring for chrome-plated rollers (15–25 μm plating): clean wax and oil off the face with 60 °C neutral soap and a soft cloth — never steel wool or scraping; light scratches are stoned out with a 2000-grit stone along the axis. Worn chrome can be stripped and re-plated 2–3 times, regrinding the profile each time. Mechanically: grease both bearings quarterly with high-temperature lithium grease; after mounting, indicate roller runout ≤0.01 mm — any excess cycles the pattern depth. For idle weeks, store rollers off the stock with rust-preventive oil, desiccant in the crate, and soft separators between rolls.
