Most workshops lower feed speed to solve bimetallic band saw blade chipping, yet ignore clamping rigidity and coolant concentration.
Excessive clamping clearance triggers micro vibration during cutting. M42/M51 high speed steel tooth tips suffer repeated impact shocks, producing spot chipping. Even with standard cutting settings, vibration can reduce blade lifespan by over 40%.
Over diluted coolant (ratio over 1:10) loses cooling‑lubricating performance. Cutting edge temperature exceeds 600°C and softens tooth tips. For high carbon and tool steel, maintain coolant ratio 1:5‑1:8 with steady kerf flushing.
Remind overseas clients to check fixtures and cooling systems. It cuts after sales complaints about chipping and breakage, reduces return costs and boosts repurchase rates.
