Slitting burr reduction is one of those \u201csmall edge\u201d problems that becomes a big cost problem fast: burr drives customer complaints, creates downstream forming issues, and quietly shortens knife life.<\/p>

This handbook is compiled by\u00a0Jerry Chu, Technical Support Specialist at\u00a0Maxtor Metal, drawing on 10+ years of field troubleshooting experience across coil slitting lines processing carbon steel, AHSS, stainless, and aluminum. It is peer-reviewed by Maxtor Metal’s application engineering team and written in a practical, verification-first spirit where the winning approach is disciplined setup windows, fast root-cause isolation, and consistent measurement.<\/p>

If your line uses\u00a0\uae08\uc18d \ub864\ub7ec \uc804\ub2e8 \ube14\ub808\uc774\ub4dc<\/em><\/strong><\/a>\u00a0(or equivalent slitter knife systems), the principles below still apply: treat the cut as a controlled fracture\/shear event, then lock down the few variables that actually move burr.<\/p>

What this handbook covers<\/strong>
A shop-floor and engineering reference to reduce edge burr by isolating root causes (clearance\/overlap, knife condition, alignment, speed, lubrication, tension), defining starting setup windows by material family, and standardizing inspection, acceptance bands, and ROI tracking. It is not a substitute for your customer print requirements \u2014 use it to converge faster, then verify against your own process capability.<\/p><\/blockquote>

Who it’s for<\/strong>
Process engineers tuning slit quality across changing grades and thicknesses; maintenance leads responsible for arbor condition, runout, and stack integrity; production managers balancing edge quality with uptime; technical procurement evaluating tooling, spacers, and regrind economics.<\/p><\/blockquote>

How to use it on a live line:<\/strong> confirm measurement discipline first \u2192 use the root-cause matrix to identify the most likely lever before changing anything \u2192 apply the material setup window as a starting point, then tune in small increments \u2192 after any change, run a short verification strip and re-measure.<\/p><\/blockquote>

Key metrics to track<\/strong>
Burr height\u00a0as % of strip thickness (and\/or absolute height when the customer specifies it) \u00b7\u00a0Width tolerance\u00a0and drift (including cumulative spacer\/stack error) \u00b7\u00a0Uptime \/ OEE\u00a0impact (setup time, changeovers, unplanned stops) \u00b7\u00a0Tool life\u00a0(tons per grind, tons per set, and failure mode: wear vs micro-chipping)<\/p><\/blockquote>

Key Takeaway:<\/strong> Burr improvement that isn’t logged and verified against the print will not stay improved.<\/p><\/blockquote>

Clearance and overlap errors<\/h3>

Start here because horizontal clearance and vertical overlap are often the highest-leverage, fastest-to-test variables. Practical industry guidance consistently ties burr to incorrect clearance and excessive overlap.The Fabricator: \u201cHow to avoid slit-in coil slitting problems\u201d (2006)<\/strong><\/em><\/a><\/p>
