Aluminum extrusion mills see aluminum sticking to the blade, built-up edge and dark end faces. This article gives high-rake TCG aluminum blades with “sharp + mirror polish” regrinding — reuse 4–7 times, end-face defects down 50–70%.
For aluminum extrusion with sticking, built-up edge and dark end faces, use high-rake (18–22°) TCG aluminum blades with Lingbang DM100 “sharp + mirror polish” regrinding — reuse 4–7 times, end-face defect down 50–70%.
An aluminum extrusion mill mainly cuts 6063/6061 architectural profiles on double-head and CNC saws, several thousand meters per day. Aluminum is soft and sticky, easily building up on the blade; end-face finish and burr-free cuts are critical, blade diameter 350–500mm.
Lingbang DM100 aluminum blade grinding machine, “sharp + mirror polish”: grind keep angle → polish face remove lump — 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 “remove lump → grind keep angle → mirror polish” SOP; regrind dull blades same shift, face stays bright.
Send dull blades in batches with before/after inspection reports — for special aluminum 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 blades
A: Soft aluminum and cutting heat weld chips to the tooth face, forming a built-up edge. Use Lingbang DM100 “sharp + mirror polish” regrinding to remove the lump and keep angle — clearly relieved.
A: High rake 18–22° cuts in more easily with better evacuation; paired with TCG and a mirror edge for higher face finish.
A: Yes. DM100 supports in-house aluminum blade regrinding — 20–40 blades per shift — with operator training.
A: Regrind main large blades in-house to keep sharp; outsource special/small-batch for flexibility. Combined cost ~30–45% of new.
