Top 10 tips for cutting granite with diamond blades

Diamond Blade Cutting Granite In stone fabrication, diamond blades are the ultimate tool for cutting granite. But improper use can reduce efficiency and shorten blade life! Today we reveal industry-approved 10 essential tips for cutting granite with diamond blades to help you become a cutting expert. 10 Essential Tips for Cutting Granite with Diamond Blades Tip 1: Choose the Right Blade Type Select diamond blade concentration and bond based on granite hardness. For high-hardness granite, use blades with 30%-40% concentration and metal bonds for stable performance. Tip 2: Equipment Inspection Matters Always check diamond blade installation and ensure equipment RPM matches the blade’s maximum rated speed before operation. Tip 3: Implement Proper Cooling Maintain continuous water cooling to prevent diamond segment overheating and reduce dust emission. Tip 4: Control Feed Rate Keep cutting speed at 1-2 meters/minute for granite. Excessive speed causes abnormal wear, while slow speed reduces productivity. Tip 5: Maintain Perpendicular Cutting Use guide rails to ensure diamond blade remains perfectly perpendicular to the stone surface. Angled cutting accelerates unilateral wear. Tip 6: Adopt Step Cutting Method For large granite slabs, use “shallow-to-deep” step cutting (3-5cm increments) to extend blade life significantly. Tip 7: Regular Blade Rotation Rotate diamond blade 180° every 30 minutes to balance wear patterns, improving utilization by over 20%. Tip 8: Clean Residue Promptly Remove stone powder buildup with a wire brush after each cut to maintain cutting precision. Tip 9: Proper Storage Conditions Store unused diamond blades in dry, temperature-controlled environments to prevent metal core corrosion. Tip 10: Monitor Cutting Sounds Listen for high-pitched screeching – this indicates need for blade inspection or parameter adjustment. Q&A Section Q: What’s the typical lifespan of a diamond blade when cutting granite? A: Quality blades can cut granite for 80-120㎡, depending on stone hardness and operation standards. Q: What if sparks appear during cutting? A: Stop immediately! This signals insufficient cooling or excessive blade wear – check water supply and blade condition. Q: Can I perform dry cutting on granite? A: While some blades allow dry cutting, water cooling is always recommended. Dry…
