Import Diamond/Cbn Grinding Wheel — Buy in Bulk from Supplier in China

The Diamond/CBN Grinding Wheel from Zhengzhou More Superhard Company is manufactured for precision grinding of hard materials including carbide, ceramics, and hardened steels. Available in vitrified, resin, metal, and electroplated bond types, these wheels feature standard diameters from 100mm to 500mm and thicknesses between 3mm and 25mm, with grit sizes ranging from 46 to 600. The product is designed for surface, OD, centerless, internal, tool, and cylindrical grinding applications, with each bond type optimized for specific material removal rates and surface finishes.

Resin-bond wheels, commonly used for carbide rod and tool grinding, typically operate at speeds under 35m/s and offer high fracture toughness for fine grinding. Vitrified bonds provide superior heat resistance and dimensional stability, making them standard for high-precision tool grinding where surface integrity is critical. Electroplated wheels are single-layer tools with diamond or CBN crystals plated directly onto a steel core, ideal for low-volume, high-accuracy tasks. Metal-bond wheels, though less common, are used for aggressive stock removal in grinding hard alloys and are typically reinforced with sintered metal matrices.

These wheels are purchased by tool manufacturers, aerospace component producers, and precision machining shops in North America, Europe, and Southeast Asia. Buyers commonly specify bond type, grit size, and concentricity tolerance of ±0.02mm. Packaging is in sealed plastic with foam inserts inside corrugated cartons, with standard MOQs of 10 pieces per size. Lead times are typically 15 to 25 days after order confirmation, and FOB Shanghai or CIF terms are standard for international shipments.

Zhengzhou More Superhard Company operates from No.171 Zhongyuan Road, Zhengzhou, China, and specializes in the production of superabrasive grinding tools. The supplier is verified as a manufacturer with a harbor trust tier, indicating active export compliance and logistics infrastructure. Their profile confirms direct production of diamond and CBN wheels but does not state annual output, employee count, or client names.

The company does not claim certifications such as ISO 9001 or CE, nor does it list export volume or years in operation. Their focus appears to be on technical customization of bond types and grit configurations rather than broad marketing. Response metrics show no recorded communication history, suggesting buyers must initiate contact for technical clarification. There is no evidence of third-party testing or quality audits published on the listing.
