Import 6-Inch Diamond Grinding Wheel — Buy in wholesale FOB from Supplier in China

Zhengzhou Hongcheng Superhard Material Co., Ltd produces a 6-inch resin bond diamond grinding wheel for surfaceGSURFACE grinder applications, primarily targeting tungsten carbide and non-metal material grinding. The wheel is available in multiple shapes including flat, cup, and dish configurations, with the 6-inch diameter being a standard mount size for many surface grinding machines. The supplier is located at No. 8 Daxue Road, Zhengzhou, Henan, China, and holds a harbor trust tier with zero recorded response rate on the available data.

Resin bond diamond wheels typically use synthetic diamond abrasives (MBS, RBS, or SDB series) embedded in a phenolic or polyimide resin matrix, offering free-cutting action and lower grinding temperatures compared to metal bond alternatives. The bond type makes these wheels suitable for both dry and wet grinding conditions, though coolant selection affects wheel loading and finish quality. Typical applications from the supplier's profile include PCD/PCBN tool grinding, tungsten carbide insert sharpening, and ceramic coating stock removal, where diamond's hardness of 10 on the Mohs scale and Knoop hardness near 8,000 HK makes it the only practical abrasive.

Buyers are typically tool manufacturers, insert resharpening services, and precision grinding shops. The supplier does not state MOQ, price, or lead time in the available data; these must be confirmed directly with Zhengzhou Hongcheng. Standard trade practice for Chinese abrasive wheels involves FOB Shanghai or Tianjin, with payment by T/T or L/C. Buyers should verify that wheel runout, balance grade, and maximum operating speed (typically 3,500-5,500 RPM for a 6-inch resin bond wheel) are tested and marked before shipment, as unbalanced rotating abrasive tools present significant safety hazards.

Zhengzhou Hongcheng Superhard Material Co., Ltd is headquartered at No. 8 Daxue Road, Zhengzhou, Henan Province, China, 450000. The city of Zhengzhou is a recognized hub for superhard material production, hosting a significant concentration of synthetic diamond and cubic boron nitride manufacturers. The supplier carries a harbor trust tier on the platform, though the response rate shows 0.00% and average response hours register as zero, indicating either limited platform activity or incomplete data capture rather than a verified operational assessment.

The company's product focus centers on resin bond diamond grinding wheels for precision grinding applications, with explicit mention of surface grinder compatibility and PCD/PCBN tool processing. No factory size, annual output, R&D staff count, or ISO certification status appears in the available profile. The listing does not disclose clientele, export history, or third-party audit results. Buyers should independently verify production capacity, quality management system certification, and whether the company manufactures its own bond formulations or sources wheels from cooperating factories before committing to volume procurement.
