DIY Texture Rollers: Steel Choice & Heat Treatment
自制花纹辊：钢种选择与热处理对比

自制花纹辊三种钢种评测：①60Si2Mn 弹簧钢——淬透性好，HRC 55 后韧性强，适合压深 ≤0.3 mm 粗纹，单辊材料成本 200 元级；②Cr12MoV——HRC 60–62 纹棱保持性最好，压深 0.5 mm 级深纹首选，但需 950–1000 °C 专业淬火炉；③45 钢表面渗氮（白亮层 0.3 mm）——成本低，适合 φ100 mm 以上大辊。工艺顺序：粗车→数控刻花或滚压成形→整体热处理→精磨外圆，热处理变形 0.05–0.1 mm 须预留磨量。对比市售雕辊（3000 元级），自制可省约 60%。
Three steels benchmarked for DIY texture rollers: (1) 60Si2Mn spring steel — good hardenability, tough at HRC 55, best for coarse patterns ≤0.3 mm deep at ~¥200 per blank; (2) Cr12MoV — HRC 60–62 holds pattern crests best for 0.5 mm-class depth, but needs a proper 950–1000 °C quench; (3) nitrided 45 steel (0.3 mm white layer) — cheapest, fine for large rollers over φ100 mm. Sequence: rough-turn → engrave or form the pattern → through-harden → finish-grind the OD, allowing 0.05–0.1 mm for distortion. DIY saves about 60% over commercial engraved rolls (~¥3,000).
