Laser-Welded Cutting Blade for Granite

Different from soft stone such as marble, granite belongs to high-hard dense stone with strong wear resistance, which puts forward higher requirements on the wear resistance and impact resistance of saw blades. This laser welded granite horizontal cutting saw blade is fully optimized for horizontal flat cutting, layered splitting and fixed-thickness trimming of large granite slabs. It adopts high-hard impact-resistant tooth type and enhanced heat dissipation gap design, which can efficiently cope with high-resistance cutting of granite, accelerate heat and chip removal, and avoid high-temperature passivation and blade stagnation. The integral laser welding process realizes metallurgical fusion of segments and matrix, with super high welding strength, effectively resisting impact load during long-term heavy-load horizontal cutting without tooth falling or weld cracking. After strict dynamic balance calibration and flatness correction, the blade runs stably with low vibration, ensuring uniform cutting thickness and neat burr-free section. It is a durable and high-efficiency special tool for mass horizontal processing of granite.

Material Introduction & Product Specification  

Material Introduction  

• Reinforced Wear-Resistant Diamond Segment: Adopting high-hardness graded diamond particles and high-temperature resistant alloy bonding formula, the diamond has strong holding force. It features super wear resistance and impact resistance, which can continuously cut high-quartz granite without rapid wear, maintaining long-term stable cutting efficiency.

• Thickened High-Rigidity Steel Matrix: Made of high-quality thickened manganese steel, after multiple quenching and stress relief treatment. The matrix has high rigidity and strong anti-deformation ability, which will not deform or shake during long-time heavy-load horizontal cutting, ensuring consistent flatness of cutting surface.

• High-Strength Laser Welding: Adopting industrial inert gas shielded laser welding, the weld seam is dense and uniform without virtual welding. It has excellent high-temperature fatigue resistance and shear resistance, adapting to frequent heavy-load cutting and effectively preventing tooth falling failure.

Product Specification

*Hubei St. Bairui Diamond Tools supports customized non-standard sizes, special flatness calibration and logo printing for laser welded granite horizontal cutting saw blades to meet diverse heavy-duty processing and bulk procurement requirements.

Core Advantages  

1. Hard Stone Dedicated Wear Resistance: Adopting granite-specific high-hard wear-resistant formula, it resists strong friction of high-quartz stone. The service life is significantly longer than ordinary flat-cut blades, solving the problem of frequent blade replacement in granite mass processing.

2. High Temperature Resistant & No Burning Blade: Optimized large heat dissipation gap + laser welding integral structure, which accelerates heat discharge during heavy-load cutting. It effectively avoids high-temperature passivation and blade burning, maintaining continuous and efficient cutting state.

3. Laser Welding Super Firm & Impact Resistant: Metallurgical fusion welding without virtual welding, with strong shear and impact resistance. It adapts to high-resistance horizontal cutting of granite, no tooth falling or cracking, and stable performance throughout the whole process.

4. High Flatness & Consistent Thickness: Strict overall flatness correction and dynamic balance calibration ensure smooth cutting operation, uniform slab thickness and neat section, reducing subsequent grinding and polishing workload.

Operation Specifications  

Before operation, check the saw blade for cracks, deformed segments and defective welds, and calibrate the horizontal level of the cutting machine workbench to prevent inclined cutting. Install the blade strictly according to the rotation direction, fasten the flange bolts firmly, and perform 60 seconds no-load test run to confirm no abnormal vibration. When cutting granite horizontally, adopt low-speed and constant-speed feeding, avoid fast feeding and forced pressing to prevent blade jamming and segment chipping. Sufficient water cooling is required for the whole process, and the water flow is increased appropriately compared with marble cutting to control cutting temperature. Do not cut heterogeneous hard impurities such as iron blocks and sand grains mixed in the stone. After work, clean the stone powder and debris on the blade surface, store it flat in a dry and dust-proof place, and check the segment wear regularly. Replace the blade in time if serious wear, tooth loss or welding crack occurs.
