Flutes—precision-machined grooves on CNC tools (end mills, drills, reamers)—are the backbone of cutting efficiency: they channel chips away from the cutting zone, reduce friction, and ensure coolant penetration. For high-performance CNC tools (HSS, carbide, PCD-tipped), flute grinding demands sub-micron tolerances, consistent helix angles, and smooth surface finishes—requirements that only specialized diamond wheels can meet. At Zhengzhou Ruizuan, we engineer diamond grinding wheels tailored for flute grinding, combining high-purity abrasives, advanced bond systems, and precision to unlock unmatched accuracy for CNC tool manufacturers.
Ruizuan’s Diamond Wheels: Engineered for Flute Grinding Excellence
Flute grinding’s unique challenges—complex helical profiles, tight dimensional control, and material hardness (up to 65 HRC)—require diamond wheels that balance sharpness, rigidity, and wear resistance. Our portfolio includes three core wheel types, each optimized for specific tool materials and flute geometries:
1. Resin Bond Diamond Wheels for Precision Finishing
Self-sharpening bond wear ensures consistent cutting edges throughout wheel life.Ultra-fine grit options deliver Ra 0.05–0.1μm surface finish, eliminating post-grinding polishing.Flexible bond system adapts to complex flute profiles (helical, straight, tapered) without chipping.
2. Metal Bond Diamond Wheels for Heavy-Duty Roughing
Grinding ratio (G-ratio) of 3,000–4,500 (vs. 500–800 for resin bonds), extending wheel life by 5x.Rigid structure handles roughing of carbide blanks (flute slotting with 0.5–1mm depth of cut).Resists wheel loading when grinding gummy materials like cobalt-binder carbide.
High-precision flute grinding is a marriage of advanced tools and optimized processes—and Ruizuan’s diamond wheels are the cornerstone of that partnership. Whether you’re producing HSS drills, carbide end mills, or PCD-tipped tools, our tailored solutions deliver the accuracy, efficiency, and longevity your operation demands.
