Technical FAQ: Diamond Blade Expertise
What diamond concentration is optimal for asphalt cutting applications?
Optimal diamond concentration ranges between 20-25% for most asphalt cutting applications. Lower concentrations (18-22%) work best for softer asphalts while harder formulations require 24-28% concentration with finer grit sizes (50/60 mesh). The specific blend depends on aggregate composition and bitumen hardness.
How does segment design impact cutting performance in concrete?
Segment geometry directly affects cutting efficiency. Wider segments (12-15mm) provide stability in deep cuts but require more power. Radial slots improve debris removal while trapezoidal segment shapes reduce drag. For reinforced concrete, alternating segment heights (staggered design) help prevent blade binding when encountering rebar.
What's the significance of bond hardness for concrete cutting?
Bond hardness controls the diamond exposure rate. For soft concrete, harder bonds (S25-S35) prevent premature wear. Hard concrete requires softer bonds (S15-S25) for proper diamond exposure. The optimal bond wears at approximately 0.15-0.25mm per linear meter cut to maintain continuous diamond exposure.
How important is RPM in blade longevity?
Operating at manufacturer-specified RPM is critical. Under-speed causes glazing as segments overheat while overspeed creates segment stress fractures. The ideal surface speed for concrete cutting is 33-38 m/s (meters per second). For example, a 500mm blade should operate at 1,300-1,500 RPM to maintain correct cutting speed.
What distinguishes asphalt-specific blades from concrete blades?
Asphalt blades feature softer bonds (to combat the material's abrasiveness), higher diamond concentrations, and specialized segment designs with wider gullets for improved debris removal. Concrete blades utilize harder bonds and tougher diamonds to handle aggregates while asphalt blades prioritize heat dissipation due to the material's thermal sensitivity.
How should contractors choose blade diameter?
Blade diameter must exceed the cutting depth by at least 100mm. For cutting depths under 100mm, 300-350mm blades offer best stability. Standard road cutting uses 500-900mm diameters. Larger diameters (1,200mm+) are used for bridge decks and thick structures. Consider equipment power capacity as diameter increases.
What maintenance extends diamond blade life?
Implement water cooling whenever possible to prevent overheating. Rotate blades regularly to ensure even wear. Periodically dress blades with abrasive concrete blocks to maintain diamond exposure. Inspect for segment cracks or weld fractures after 5 hours of operation. Store horizontally in dry conditions to prevent core warping.
