FAQ: Technical Q&A
1. What material is used for the segment and core of a diamond blade for cutting granite?
The segments use a blend of synthetic diamond crystal (monocrystalline) within a cobalt-nickel based metal bond. The steel core is typically 42CrMo high-toughness alloy, ensuring fatigue resistance and precise stability.
2. What is “segment height”, and how does it affect blade life?
Segment height refers to the thickness of the diamond-carrying segment (usually 10-15mm). Higher segment means more diamond/equivalent longer lifespan on granite before the segment wears out.
3. Which certifications matter for granite diamond blades?
Key certifications include ISO 9001:2015 (quality control), EN13236 (abrasive safety Europe), and ANSI B7.1 (US). These ensure performance, safety, and international warranty eligibility.
4. What is the recommended RPM and feeding speed for granite cutting?
For a 350mm blade, 2800–3400 RPM is optimal, with linear feed speed of 2–4 m/min on wet saws to balance speed and precision.
5. Can these blades be used for both dry and wet cutting?
Most premium diamond blade for cutting granite models support wet cutting (for cooling, life extension); some turbo professional types also permit controlled dry use, but lifespan and debris control is superior with wet operation.
6. Are these blades suitable for CNC routers or only manual saws?
High-precision models with a sandwich core and reinforced edge are ideal for CNC routers, bridge saws, tile saws, and angle grinders. For oscillating multi-tool blades, a thinner core is essential.
7. How is blade balance and noise managed?
Advanced models utilize CNC peripheral balancing and laser noise-damping slots. Compliance with EN13236 limits ensures vibration/noise under regulatory thresholds during continuous operation.
