MachiningVitrified Diamond Grinding Wheels by Ruizuan: Precision Grinding & Regrinding for PCD/CBN Inserts, MCD Tools & PCD Reamers
Polycrystalline diamond (PCD), cubic boron nitride (CBN), monocrystalline diamond (MCD) tools, and PCD reamers represent the gold standard of precision machining for hard-to-cut materials—from aerospace titanium alloys and automotive carbide components to semiconductor ceramics and wood composites. Grinding and regrinding these superhard tools demands an abrasive solution that delivers uncompromising precision, thermal stability, and wear resistance, as generic grinding wheels fail to preserve the critical geometric accuracy and cutting edge integrity of these high-value tools.
Zhengzhou Ruizuan’s vitrified (ceramic) diamond grinding wheels are engineered exclusively for the grinding and regrinding of PCD/CBN inserts, MCD tools, and PCD reamers. Our proprietary vitrified bond formulation, paired with high-purity diamond abrasives, addresses the unique challenges of superhard tool machining—eliminating thermal damage, maintaining micron-level tolerances, and extending tool life. As a trusted manufacturer with decades of superabrasive expertise, our vitrified diamond wheels set the industry benchmark for precision, efficiency, and consistency in superhard tool grinding across aerospace, automotive, mold & die, and electronic manufacturing sectors.
Core Technical Features of Ruizuan’s Vitrified Diamond Grinding Wheels
Ruizuan’s vitrified diamond grinding wheels are the product of advanced material science and precision engineering, with every component optimized for the grinding and regrinding of PCD, CBN, and MCD superhard tools. Our wheels stand apart with these foundational technical attributes:Proprietary Nano-Reinforced Vitrified Bond; High-Purity Monocrystalline Diamond Abrasives; Micron-Level Dimensional Precision;Customizable Wheel Geometries.
Unmatched Advantages for PCD/CBN/MCD Tool Grinding & Regrinding
Ruizuan’s vitrified diamond grinding wheels outperform resin-bonded and metal-bonded diamond wheels for superhard tool machining, delivering benefits that directly boost machining efficiency, tool quality, and operational cost savings:
1. Thermal Stability Eliminates Superhard Tool Damage
The low thermal conductivity of our vitrified bond and controlled porosity structure enable efficient coolant flow and chip evacuation, reducing grinding temperatures by 40% compared to resin-bonded diamond wheels. This eliminates graphitization of diamond (a critical issue for PCD/MCD tools) and delamination of CBN inserts, preserving the structural integrity of the tool’s cutting edge and substrate during grinding and regrinding.
2. Exceptional Shape Retention Preserves Tool Geometry
PCD/CBN inserts, MCD tools, and PCD reamers rely on precise rake angles, clearance angles, and cutting edge radii (≤5μm) for optimal performance. Our rigid vitrified bond maintains dimensional accuracy (±1μm) across long production runs, avoiding the bond wear and deformation that plagues resin-bonded wheels. This ensures consistent tool geometry for every grind and regrind, eliminating post-processing rework.
3. Ultra-Smooth Surface Finishes Boost Tool Performance
The sharp, uniform diamond grains and controlled grinding action of our vitrified wheels deliver surface finishes as low as Ra 0.02–0.05μm on PCD/CBN cutting edges and MCD tool surfaces. This eliminates micro-roughness that causes chip adhesion and tool wear, extending the working life of the finished PCD/CBN inserts, MCD tools, and PCD reamers by 25–30% in real-world machining applications.
