High-performance circular saw blades and micro-cutting discs manufactured via hot-press sintering and laser welding technology for industrial tile, ceramic slab, and natural stone processing.
Unlocking superior tool longevity, zero-chipping edge retention, and optimal kerf economics across hard ceramic substrates and dense metal-ceramic matrices.
In modern precision manufacturing, processing engineered ceramics (such as alumina Al₂O₃, zirconia ZrO₂, silicon carbide SiC) and dense sintered porcelain slabs requires dynamic control over the brittle-to-ductile cutting transition. Traditional abrasives suffer rapid bond degradation and severe thermal micro-cracking when operating under high tangential feed forces.
At JIAYAN Superhard Materials, our OEM/ODM tooling architecture utilizes advanced Vacuum Hot-Press Sintering Metallurgy. By encapsulating high-purity synthetic diamond micro-crystallites (grade MBD-12 / PCD series) within an ultra-dense cobalt-nickel-copper matrix reinforced with micro-alloyed tungsten carbide (WC), our tools maintain a controlled self-sharpening rate while maintaining structural rigidity up to 900°C.
Leveraging Anhui and Henan’s superhard material industrial clusters to deliver uncompromised cutting precision, low minimum order quantities, and massive total cost of ownership (TCO) optimization.
Located at the epicenter of China’s synthetic diamond raw material production, JIAYAN controls quality from sub-micron diamond powder synthesis to final cold pressing, hot sintering, and automated laser segment welding. This eliminates middleman markups and reduces raw material procurement lead times by up to 60%.
One size does NOT fit all. Stone hardness, porcelain density, CNC bridge saw horsepowers, and water cooling flow rates vary globally. Our in-house metallurgical laboratory customized metal powder bonds (Cobalt, Bronze, Iron, Nickel, Tungsten Carbide) tailored to match your specific target market substrate specs.
Every single blade undergoes dynamic balance testing, segment shear strength testing (>600 MPa laser weld shear load capability), and side-runout checks using optical precision lasers. We guarantee 100% adherence to European EN13236 safety standards for high-speed cutting discs.
JIAYAN Superhard operates automated hot-press sintering furnaces, multi-axis CNC laser welding cells, and automatic tensioning benches. As a proud member of the China Superhard Material Association, our manufacturing plant delivers over 200,000 diamond saw blades and cutting discs per month to global buyers in North America, Europe, the Middle East, and Southeast Asia.

High-density porcelain slabs (Laminam, Neolith, Dekton) require zero-chipping, smooth edge finishes. Our ultra-thin J-Slot and continuous rim saw blades eliminate edge cracking and micro-fractures under 2,000–3,000 RPM wet cutting environments.
For Class 4 & 5 abrasive granites (Mohs hardness 7+), our 350mm to 800mm laser-welded keyhole and turbo-segment blades utilize heavy cobalt bond matrices that withstand extreme heat and severe abrasive friction without segment loss.
Machining non-oxide ceramics (Silicon Nitride, Boron Carbide) requires specialized sub-micron diamond grit sizes with high diamond concentration (50%-75%) to maintain dimensional precision and micro-inch surface finish tolerances.
Fast-cutting turbo-segment diamond blades engineered for reinforced concrete, asphalt, curing pavement, and heavy clay bricks. Designed for high feed speeds, dry or wet operation, and maximum tool resistance to lateral wear.
Use this technical specification matrix to select the optimal diamond saw blade geometry, segment height, bond hardness, and recommended peripheral cutting speed for your factory setup.

From raw material metallurgical formulation to custom private labeling and global logistics—how JIAYAN turns client specifications into market-leading cutting tools.
Our engineers evaluate your cutting equipment RPM, power rating (kW), feed rate, water supply pressure, and target material abrasive index to define optimum tool geometry.
We blend synthetic diamond powders (mesh size 30/40 to 230/270) with precise cobalt, copper, nickel, and tungsten carbide concentrations tailored specifically for your wear rate target.
Cold-pressed green compacts are high-temperature vacuum sintered, then joined to tensioned high-alloy steel cores using fully automated German laser welding equipment.
Each blade core undergoes tensioning adjustments to guarantee vibration-free cutting at working speeds up to 80 m/s, preventing deflection under high lateral torque.
