In fields such as deep stone processing, infrastructure engineering, and high-end drilling, traditional diamond tools have long faced challenges such as low efficiency in processing hard materials, rapid wear under high-load conditions, and insufficient adaptability to specialized scenarios. For instance, when cutting ultra-hard granite with a hardness of F=20, ordinary tools often require replacement after just 2 hours, while the wear rate when drilling C80 high-strength reinforced concrete can exceed 30%. Addressing these industry bottlenecks, the JCB JSD series of synthetic diamonds has emerged as a key solution, driving advancements in processing technology and resolving the conflict between efficiency and cost with its exceptional crystal properties and adaptability to diverse scenarios.
Precision-Controlled Balance of Strength and Sharpness
The JCB JSD series is a high-performance synthetic diamond tailored for sawing applications, with grain sizes ranging from 20/25 to 50/60. It features a uniform golden hexahedral crystal morphology, a result of its stringent precision synthesis process. Under high pressure of 5–8 GPa and high temperatures of 1400–1800°C, achieved using a six-anvil press, the R&D team employs 99.99% high-purity graphite as the carbon source. The crystal growth rate is precisely controlled within 0.5 μm/h to ensure structural integrity, impurity content, and mechanical properties meet predefined standards.
To suit various processing scenarios, the JSD series offers differentiated grades, from the premium JSD90 to the entry-level JSD10, through gradient designs in crystal purity and structural regularity:
JSD90: Diamond purity exceeds 99.9%, with hexahedral crystal integrity over 98% and nearly zero lattice defects. Its static strength (Newton) and thermal stability (TTI) comply with the international ISO 13274 standard, and its wear resistance is 40% higher than that of ordinary synthetic diamonds.
JSD50: Crystal purity is approximately 95%, with regularity reduced to 90%. It balances medium strength with sharpness for high-speed cutting, making it suitable for medium-load processing.
JSD10: Although crystal regularity is only 50%, it exhibits exceptional edge sharpness and self-sharpening, enabling high-precision cutting under light loads.
Before leaving the factory, each batch of JSD products undergoes multi-dimensional testing, including scanning electron microscopy (SEM) for crystal morphology, X-ray diffraction (XRD) for impurity analysis, and mechanical performance testing for impact toughness, ensuring performance deviations between batches are controlled within 5%.
An Efficiency Revolution from Infrastructure to High-End Processing
The JSD series has deeply penetrated multiple core industries, reshaping processing scenarios with its "performance adaptability + efficiency enhancement":
In stone processing, JSD80 is suitable for cutting hard granite with F=15. Data from a large stone processing plant in Fujian shows that a 1200mm diameter saw blade equipped with JSD80 achieves a cutting speed of 25 m/min, 30% faster than traditional blades. A single blade can cut 800 m² of granite, reducing overall tool costs by 25%. JSD50, designed for soft marble and sandstone, prevents edge chipping during high-speed cutting and shortens processing cycles by 15%.
In infrastructure engineering, brazed tools made with JSD90 are "game-changers" for drilling high-strength materials. In a highway expansion project, JSD90 drill bits achieved a lifespan of 120 holes when drilling C80 high-strength concrete, 3.5 times longer than ordinary diamond drill bits. The construction wear rate dropped from 28% to 8%, directly shortening the project timeline by 20%.
In high-end processing, JSD30 and JSD20, with their exceptional sharpness, are the preferred choices for processing gemstones and crystals. Micro-drill tools using JSD20 for jade processing achieve a surface roughness below Ra 0.15 μm, enabling "cutting replace grinding" and improving processing efficiency by 40%. Additionally, they can be mixed with high-grade diamonds in a 3:1 ratio to precisely adjust tool sharpness for processing gemstones of varying hardness.
Furthermore, JSD90 geological drill bits tackle hard rock formations in deep oil and gas wells, while JSD50 grinding blocks enable scratch-free polishing of ultra-thin glass. Today, "JSD tools" have become synonymous with "efficient, low-wear processing" across multiple industries.
ospectsRiding the Wave of Industry Upgrades, Opening a New Cycle of Localization
The global synthetic diamond tool market has now exceeded $8 billion, with stone processing and infrastructure engineering accounting for over 60% of the market and maintaining an annual growth rate of over 8%. However, the domestic high-end synthetic diamond tool market has long relied on imports, with a localization rate of less than 30%. Against this backdrop, the market potential of the JSD series is rapidly being realized:
On one hand, its product matrix, covering more than 10 grades, can precisely match full-scene applications such as "heavy-duty engineering drilling," "batch stone processing," and "high-end gemstone precision cutting," meeting the differentiated cost and performance demands of both large infrastructure enterprises and small processing workshops. On the other hand, in the context of the "dual-carbon" initiative and the trend toward green processing, the long lifespan and low wear characteristics of JSD tools can reduce diamond waste emissions by 70% and lower carbon emissions by approximately 12% per 10,000 processed products, aligning with EU REACH environmental standards and domestic green manufacturing policies.
Industry analysts note that as the localization of high-end synthetic diamonds accelerates, the JCB JSD series, with its cost-performance advantage of "performance comparable to international top-tier brands at only 60% of the price," is expected to increase its domestic market share from the current 8% to 15% within the next three years. Simultaneously, it will gradually penetrate markets in Southeast Asia, the Middle East, and other regions with robust infrastructure development, positioning itself as a mainstream tool material in the global stone and engineering processing sectors.
