The 400H brazed diamond saw blade employs advanced brazing technology to securely bond diamond particles onto a high-strength alloy matrix. This innovative method substantially improves wear resistance and cutting efficiency, making it ideal for cutting a range of hard materials such as concrete, granite, and marble. Designed with a 400 mm diameter, the blade optimizes cutting depth and offers both dry and wet cutting modes. Enhanced blade tip design reduces noise and vibration to improve operator comfort and control. This article delves deep into the blade's core technologies, supported by real-world performance data and customer application cases, to showcase its versatile compatibility across diverse work environments in construction, décor, and stone processing industries.
Brazing technology, used in the manufacturing of the 400H saw blade, involves fusing diamond particles onto the alloy base using a high-temperature filler metal. Compared to traditional sintering, brazing ensures stronger adhesion, which directly translates to extended blade life and sustained sharpness during heavy-duty cutting tasks. Tests show that blades produced with brazed diamonds retain up to 40% more cutting segments after 30 hours of continuous use, compared to conventional bonded blades.
Equipped with a 400 mm diameter suitable for heavy industrial use, the 400H saw blade demonstrates excellent performance when cutting high-hardness materials:
| Material | Cutting Speed (m/min) | Blade Wear Rate (%) | Typical Applications |
|---|---|---|---|
| Concrete | 18 | 0.8 | Building foundations, roadworks |
| Granite | 14 | 1.0 | Monuments, countertops |
| Marble | 16 | 0.6 | Interior décor, flooring |
An often overlooked but critical feature of the 400H blade is its advanced blade tip geometry. Its patented wave-patterned segments minimize cutting resistance, effectively reducing operational noise by approximately 15% and vibration amplitude by 20%. These improvements translate into less operator fatigue and enhanced safety, especially during extended periods of use.
The blade’s design supports both dry and wet cutting modes without compromising cutting speed or longevity. In wet cutting, diamond particles benefit from continuous cooling which slows down thermal degradation, while dry cutting allows flexibility for on-site applications lacking water supply. Performance testing indicates that the blade maintains top cutting efficiency with only a 5% wear rate increase under dry conditions compared to wet operation.
A leading stone fabrication company in the United States integrated the 400H brazed diamond saw blade in their production line for granite and marble slabs. The switch from conventional blades reduced saw downtime by 30%, increased cutting throughput by 18%, and improved surface finish quality, which resulted in fewer reworks. Their operators reported marked decreases in vibration discomfort during 8-hour shifts, leading to better workplace ergonomics and morale.
When compared to typical sintered or electroplated diamond saw blades, the 400H excels with:
These factors contribute to a higher return on investment and less frequent blade replacements, setting a new standard for cost-efficiency and reliability in the market.
