Import 900 Mm Resin Bond Diamond Grinding Wheel — Buy in wholesale FOB from Supplier in China

This 900 mm resin bond diamond grinding wheel is engineered for precision grinding of tungsten carbide, PCD/PCBN tools, ceramic coatings, and non-metallic materials where friable abrasives would load or degrade prematurely. The resin bond system uses synthetic resin as the matrix material, offering cooler cutting action and finer surface finishes than metal or vitrified bonds at equivalent concentrations. At 900 mm outer diameter, this wheel sits at the upper end of standard peripheral grinding wheel sizes, typically requiring dedicated arbor mounting and substantial machine rigidity. The supplier indicates availability in flat, cup, and dish profiles to suit peripheral, face, and tool-and-cutter grinding applications respectively.

The diamond abrasive in resin bond wheels is typically synthetic monocrystalline or polycrystalline diamond, with concentration expressed as 25% to 100% (by volume, with 100% equal to 4.4 carats per cubic centimetre). The exact concentration, mesh size, and bond hardness grade are not stated in the source data and must be requested from Zhengzhou Hongcheng Superhard Material Co., Ltd. Good free-cutting and abrasion resistance are claimed, which in resin bond wheels typically correlates with medium-to-hard bond grades and regular diamond sizes of 100/120 to 400/500 US mesh for finish grinding operations. Both dry and wet grinding are supported, though wet operation generally extends wheel life and suppresses thermal damage to carbide substrates.

Primary applications include tool-room grinding of PCD and PCBN turning inserts, cylindrical grinding of tungsten carbide rolls and dies, and finishing of thermally sprayed ceramic coatings on aerospace and industrial components. Buyers should specify the required profile (flat 1A1, cup 6A2, dish 12A2, or other), bore diameter, and keyway configuration to ensure machine compatibility. Given the Henan location, Zhengzhou sits within China's superhard materials cluster, with access to synthetic diamond feedstock and established freight corridors to Qingdao or Tianjin ports for export.

Zhengzhou Hongcheng Superhard Material Co., Ltd is located at No.8 Daxue Road, Zhengzhou 450000, Henan Province, China. Zhengzhou and the broader Henan region form China's principal superhard materials manufacturing cluster, with synthetic diamond production and abrasive tool fabrication representing established local specialisations. The supplier holds a Harbor trust tier on the platform, though like many specialised manufacturers in this sector, the response rate is recorded at 0.00% with no average response hours data, indicating limited or unrecorded platform engagement rather than operational scale.

The company profile does not state year of establishment, factory certification, research and development expenditure, named OEM clients, or production capacity in terms of wheel count or annual output. Buyers should request a factory profile, quality management system certification (ISO 9001 minimum, ISO 17025 for testing laboratory if relevant), and sample wheels for cutting test validation. The superhard materials sector in Henan includes both integrated manufacturers and trading companies; direct verification of in-house bond mixing, diamond sieving, and hot pressing capabilities is advisable before volume commitment.
