When cutting solid wood and logs, resin gums up the teeth and the cut goes fuzzy or burnt, dragging yield down. This article gives low-tooth high-rake blade degumming and high-frequency regrinding — reuse 3–5 times, fuzz/burn defects down 50–70%.

A solid-wood furniture / log board mill mainly cuts resinous species — oak, pine, birch, beech — where tooth gullets clog and the edge dulls fast. Main equipment is precision sliding table saws and band saws, blade diameter 300–400mm, slower speed with fast feed, demanding a smooth cut surface.

• ⚠Resin-gummed teeth: wood resin piles up in the gullets, wrapping the edge so cutting becomes rubbing and heat builds.
• ⚠Fuzzy / burnt cut: a dull edge generates friction heat, scorching the wood and raising the surface nap — downstream sanding time doubles.
• ⚠Frequent changes: resinous material wears fast; a new blade dulls in 3–5 days, outsourcing is slow and the line slows.
• ⚠High blade cost: constantly buying new blades inflates monthly spend, and special tooth profiles are hard to stock.

• ✓Tooth form: low-tooth-count high-rake TCG (ATB), consistent left/right tooth height to reduce gumming.
• ✓Tooth count: 40–60T; lower for rough cuts, higher for fast feed.
• ✓Material: carbide YG8/YC8, rake 18–22°, clearance 15°, sharpness first.
• ✓Spec: 300/350/400mm diameter, bore per machine (30/60mm).

• ✓Reuse 3–5 times per blade, regrind cost ~30–45% of new (by condition).
• ✓Fuzz/burn defect down 50–70%, smoother cut, less downstream sanding.
• ✓Changeover downtime down 40%+, line tempo more stable.
