Double disc grinding wheels are high-precision abrasive tools specifically designed for the simultaneous grinding of two parallel end faces of workpieces. Featuring a symmetrical structural design with grinding surfaces on both sides of the wheel body, they enable one-time clamping to complete double-end processing, fundamentally eliminating dimensional deviations 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 constructed from a 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 300 mm–1500 mm and an abrasive layer width of 40 mm–350 mm, the products can be customized to fit mainstream grinding machine brands including Supfina, Peter Wolters, Koyo, and Lam Plan.
Core Advantages: Driving Efficiency and Precision Upgrades
These double disc grinding wheels integrate innovative material technology and structural design, delivering key advantages in the global market:
-
Ultra-High Grinding Efficiency
Simultaneous double-end grinding reduces processing cycle time by 30%–50% compared with single-side grinding. Sharp diamond grains and optimized pore structure ensure efficient chip removal, supporting high-volume production of precision parts without quality compromise.
-
Exceptional Dimensional Precision
Symmetrical design and strict dynamic balance calibration guarantee consistent flatness and parallelism. For thin-walled or brittle materials, the low-stress grinding process effectively controls workpiece warpage within ±5 μm.
-
Extended Service Life
High-purity diamond grains with excellent wear resistance and nano-modified bonding technology greatly extend service life. Under standard working conditions, the dressing cycle is extended 2–3 times compared with conventional wheels, reducing downtime for wheel replacement.
-
Wide Material Adaptability
Compatible with bearing steel, tool steel, stainless steel, carbide, ceramics (Al₂O₃, ZrO₂), SiC substrates, and sintered metal parts, meeting diverse grinding needs across multiple industries.
-
Customizable Solutions
Tailored solutions for bond type, grain size, and wheel structure are provided based on workpiece material, size, and precision requirements, ensuring optimal grinding performance.
