    Customer Profile & Application

    An industrial aluminum plate processor mainly cuts 5–50mm thick plates and ingots on horizontal/vertical large aluminum cutters. Single pieces are heavy and high-value; thick-plate corner break scraps offcuts at high material cost. Blade diameter 800–1600mm, needing long-stroke equipment to regrind.

    02

    Key Pain Points

    • ⚠Thick-plate corner break: entry/exit corner chips, scrapping offcuts, wasting material.
    • ⚠Delamination / tearing: wrong tooth count tears between layers, rough section.
    • ⚠Large blades hard to regrind locally: big diameter, no local equipment, mail-in is costly and slow.
    • ⚠Long changeover downtime: large blades take long to remove/install, high downtime loss.
    03

    Blade Selection

    • ✓Tooth form: medium-low tooth-count TCG or step tooth, smooth evacuation for thick cuts.
    • ✓Tooth count: 40–60T (large diameter), lower for thick plate.
    • ✓Material: carbide YG12/YC12, impact-resistant, mirror edge.
    • ✓Spec: 800/1200/1600mm diameter, bore per machine, face runout ≤0.03mm.

    Production & Regrinding Setup

    Long-stroke in-house

    Lingbang long-stroke grinder covers large-diameter aluminum blades, SOP: deglue → check double runout → grind keep angle → polish, rotating blades, regrind when dull.

    Regrind center mail-in

    Lingbang regrind center accepts large blades, per-blade pricing with inspection report — for mills without large equipment.

    Actionable Plan

    Plan A: On-site / in-house large blade

    Equip a long-stroke grinder for a line-side regrind station, rotating blades + regrind when dull — saves mail-in and downtime.

    Plan B: Centralized mail-in

    Mail large blades in batches, handover with before/after photos + inspection report — for occasional single blades.

    Combo tip: mainly on-site in-house to save mail-in, occasional large blade mail-in as backup — balancing offcut yield and downtime.

    Expected Results (typical range, by condition)

    • ✓Reuse 3–5 times per blade, regrind cost ~35–50% of new (by condition).
    • ✓Corner-break defect down 50–70%, less offcut scrap, material saved.
    • ✓Changeover downtime down 40%+, heavy-piece line more continuous.

    Q

    FAQ

    Q1How to avoid corner break on thick aluminum plate?

    A: Choose step/TCG medium-low tooth-count blades with angle-keep sharp regrinding. Use Lingbang long-stroke grinder — corner-break defect down 50–70%, less offcut scrap.

    Q2Can't regrind large-diameter aluminum blades locally?

    A: Equip a Lingbang long-stroke grinder for on-site in-house regrind, or mail to Lingbang regrind center — both with inspection reports.

    Q3What diameter does Lingbang long-stroke grinder cover?

    A: Covers large-diameter aluminum blades (commonly 800–2000mm), rotating blades + regrind when dull — suited to continuous thick-plate work.

    Q4In-house or mail-in?

    A: Mainly on-site in-house to save mail-in, occasional large blade mail-in as backup. Combined cost ~35–50% of new.
