Steel structure and hardware dry cutting see heating tooth break and short life. This article gives heat-resistant alloy dry-cut tooth blades with high-frequency angle-keep regrinding — reuse 3–5 times, cut defect down 40–60%, regrind cost ~30–40% of new.
For steel structure/hardware dry cutting with heating tooth break and short life, use heat-resistant alloy dry-cut tooth blades with Lingbang DM100 high-frequency angle-keep regrinding — reuse 3–5 times, cut defect down 40–60%, regrind cost ~30–40% of new.
A steel-structure / hardware factory mainly cuts carbon steel and stainless profiles and bars on high-speed dry cutters and metal circular saws, dry cutting without coolant. High heat, easy tooth break, blade diameter 250–400mm, demanding cut squareness.
Lingbang DM100 dry-cut blade grinding machine, high-frequency angle-keep regrinding: grind keep angle → top polish — 20–40 blades per shift.
Lingbang regrind center accepts mail-in blades, 48-hour return — ideal for small mills without space.
Buy DM100 + training, build "check runout → angle-keep grind → polish" high-frequency SOP; regrind dull blades same shift.
Send dull blades in batches with before/after inspection reports — for special dry-cut blades.
Lingbang DM100 circular saw blade grinding machine focuses on precision grinding, with the motto "Precision circular saw blade grinding — choose Lingbang for quality blades." We offer free sample test grinding, factory visits and operator training.
Precision circular saw blade grinding — choose Lingbang for quality bladesA: No coolant, tooth tip overheats and oxidizes, breaking. Use Lingbang DM100 high-frequency angle-keep regrinding to hold angle and sharpness — cut defect down 40–60%.
A: Heat-resistant teeth with small rake (8–12°) for impact resistance, paired with cobalt carbide for heat-crack resistance.
A: Yes. DM100 supports in-house dry-cut blade regrinding — 20–40 blades per shift — with operator training.
A: Regrind main dry-cut blades in-house to keep angle; outsource special/small-batch for flexibility. Combined cost ~30–40% of new.
