Explore our certified catalog of diamond circular saw blades, engineered with proprietary cobalt-bronze matrix formulation for bridge saws, automated profiling tables, and handheld grinders.
Headquartered in the advanced manufacturing corridor of Wuhu, China, JIAYAN Superhard Materials operates as a tier-one OEM/ODM research and production plant for diamond circular saw blades, grinding discs, and custom cutting tools. With over a decade of metallurgy-driven innovation, we solve the most persistent challenges in structural ceramics, large-format porcelain slabs, and architectural stone fabrication.
Our factory integrates automated multi-axis hot isostatic pressing (HIP), German high-frequency laser welding systems, and optical dynamic balancing inspection. By strictly adhering to international safety specifications (EN13236 and ANSI B7.1), JIAYAN delivers industrial cutting blades that guarantee zero edge chipping, extended linear cutting lifespan, and high feed velocities under extreme production environments.
The cutting efficiency of a diamond ceramic blade depends on the continuous thermodynamic synchronization between synthetic diamond crystal degradation and the wear rate of the sintered metal bond matrix.
We select ultra-tough Ti-doped synthetic monocrystalline diamond grits (Grade MBD8/MBD12) with optimized octahedral crystal habits. Controlled mesh grading (#60/70 for ultra-fast roughing up to #200/230 for micro-fine glazed finishes) ensures razor-sharp cleavage planes that micro-fracture rather than pull out prematurely.
Our proprietary vacuum-sintered binders combine sub-micron Cobalt (Co), Copper (Cu), Nickel (Ni), and Tin (Sn) powders. By adjusting the Rockwell B hardness (HRB 85–105), the bond precisely exposes fresh diamond facets at the exact rate needed to cut dense vitrified porcelain without glazing or overheating.
The blade body is laser-cut from German 75Cr1 or Japanese 65Mn spring alloy steel, hardened to HRC 42–46. Each core undergoes mechanical roll-tensioning and CNC dynamic balancing to ensure lateral deflection stays under 0.03mm even under high circumferential speeds exceeding 40 m/s.

Direct proximity to top-tier synthetic diamond synthesizers gives us priority selection of diamond crystals and sub-micron metal powders at volatile-free pricing.
Multi-cavity automated hot-press machines guarantee precise temperature (+/- 2°C) and uniform pressure distribution across every single segment batch.
100% optical runout verification, ultrasonic weld shear-strength testing, and automated segment dressing guarantee ready-to-cut performance out of the box.
Monthly output exceeding 250,000 diamond discs, flexible container consolidations, customized retail packaging, and dedicated international customs documentation.
As the construction and interior surfaces market shifts toward ultra-compact sintered surfaces and porcelain jumbo slabs, traditional abrasive tooling has become obsolete.
Sintered slabs (Mohs hardness 7–8, zero porosity, high internal tension) easily fracture if the blade generates excessive lateral vibration. JIAYAN's continuous mesh rim design relieves internal tension instantaneously during cutting, preventing corner breakout and micro-hairline fractures.
To minimize material loss on expensive imported porcelain and reduce airborne respirable crystalline silica (RCS), we have engineered ultra-thin 1.0mm and 1.2mm continuous rim blades equipped with reinforced hub flanges to eliminate core wobble.
Compliant with European workplace noise directives, our 300mm–400mm bridge saw blades feature dual-steel plates laser-bonded with a micro-thin acoustic copper foil core, suppressing high-frequency harmonics by over 12 dB(A).
From automated CNC tile processing plants to demanding on-site architectural installations, our blade matrices are customized to distinct machinery kinematics and cutting dynamics.
Equipped on 5-axis CNC bridge saws for 45° miter cuts, sink cutouts, and countertop profiling on 12mm–20mm sintered slabs without chipping or edge deflection.
Integrated into multi-head continuous ceramic chamfering and squaring machines operating 24/7 with long maintenance intervals and consistent wear rates.
Reinforced 115mm and 125mm handheld blades featuring turbo-mesh slots for fast, dust-evacuated dry cutting by professional tile contractors.
Ultra-fine diamond grit matrix discs optimized for delicate glass mosaics, decorative borders, and precision radial waterjet pre-cuts.
