Zhengzhou Ruizuan's Double Disc Grinding Wheels are high-precision abrasive tools specifically designed for simultaneous grinding of two parallel end faces of workpieces. The product features a symmetrical structural design with grinding surfaces on both sides of the wheel body, enabling one-time clamping to complete double-end processing, which fundamentally eliminates the dimensional deviation caused by multiple clamping in traditional single-side grinding.
Crafted with high-purity synthetic diamond grains (or CBN grains for specific materials) and advanced bonding systems, the wheels are available in resin, vitrified, and metal bond options to match different grinding scenarios. The wheel body is made of high-strength aluminum or steel matrix, ensuring excellent dynamic balance performance (up to G1 precision grade) even at high linear speeds (35-60 m/s). With a diameter range of 300mm-1500mm and an abrasive layer width of 40mm-350mm, the product can be customized to fit mainstream grinding machine brands such as Supfina, Peter Wolters, Koyo, and Lam Plan.
Core Advantages: Driving Efficiency and Precision Upgrades
Zhengzhou Ruizuan's Double Disc Grinding Wheels integrate innovative material technology and structural design, delivering six core advantages that stand out in the global market:
- Ultra-High Grinding Efficiency: Simultaneous double-end grinding reduces processing cycle time by 30%-50% compared to single-side grinding. The sharp diamond grains and optimized pore structure ensure efficient chip removal, realizing high-volume production of precision parts without compromising quality.
- Exceptional Dimensional Precision: The symmetrical design and rigorous dynamic balance calibration guarantee consistent flatness and parallelism of workpieces. Even for thin-walled or brittle materials, the low-stress grinding process effectively controls workpiece warpage within ±5μm.
- Extended Service Life: High-purity diamond grains with excellent wear resistance and nano-modified bonding technology significantly extend the wheel's service life. Under standard working conditions, the dressing cycle is extended by 2-3 times compared to conventional wheels, reducing downtime for wheel replacement.
- Wide Material Adaptability: Compatible with a full range of materials including bearing steel, tool steel, stainless steel, carbide, ceramics (Al₂O₃, ZrO₂), SiC substrates, and sintered metal parts, satisfying diverse grinding needs in multiple industries.
- Customizable Solutions: Based on customers' specific processing requirements (workpiece material, size, precision), Zhengzhou Ruizuan provides tailored solutions for bond type, grain size, and wheel structure, ensuring optimal grinding performance.
