Diamond Cylindrical Grinding Wheels

High-Performance Vitrified Diamond Wheels for Precision Cylindrical Grinding of Superhard Materials

ZYsuperhard’s Vitrified Bond Diamond Cylindrical Grinding Wheels are expertly engineered to meet the demanding requirements of grinding ultra-hard and difficult-to-grind materials. Designed for high-precision industrial applications, these wheels deliver exceptional performance and longevity when cylindrically grinding PCD, PCBN, tungsten carbide, technical ceramics, natural diamond, and other ultra-hard substances.

The Vitrified Bond Advantage: Precision, Durability, and Cool Cutting Efficiency

Our advanced vitrified bond technology is the cornerstone for achieving superior results on these difficult-to-grind materials, offering distinct advantages:

• Exceptional Rigidity & Form Holding: The robust, rigid ceramic bond structure minimizes wheel deflection under load. This ensures excellent geometric accuracy (roundness, cylindricity, parallelism) on the workpiece and superior shape retention of the wheel itself, critical for maintaining tight tolerances over long grinding cycles.
• Controlled Porosity for Optimal Performance: The engineered, interconnected porous structure within the bond facilitates efficient coolant delivery directly into the grinding zone and promotes effective chip evacuation. This significantly reduces grinding heat, prevents wheel loading (clogging) even in demanding applications, and minimizes the risk of thermal damage to sensitive workpiece materials.
• Strong Abrasive Grip & Tuned Self-Sharpening: The vitrified bond provides a tenacious grip on the premium diamond abrasive grains while also being formulated for controlled micro-fracturing (self-sharpening). This dynamic balance ensures continuous exposure of fresh, sharp cutting edges, resulting in both strong, consistent grinding force and remarkably long grinding life between dressing operations.
• Chemical & Thermal Stability: Vitrified bonds are inherently resistant to chemical reactions with most grinding coolants and possess excellent thermal stability, ensuring consistent and predictable grinding performance.

Key Features:

• Premium Diamond Abrasive: Utilizes high-quality, carefully selected and graded diamond grains chosen for maximum cutting efficiency, wear resistance, and durability when grinding specific ultra-hard materials.
• Precision Manufacturing & Balancing: Produced using state-of-the-art manufacturing processes to guarantee high dimensional accuracy, excellent wheel balance, and structural integrity. This ensures smooth, stable, vibration-free operation, especially important at high grinding speeds.
