Selected nylon fibers, high-performance resin binders, and first-grade abrasives; adopted multi-layer non-woven fabric winding and tightening process with glass fiber cores, featuring excellent conformability and structural stability to meet the processing requirements of complex shapes of aircraft blades.
• High cutting efficiency: Burr removal speed is 30%-50% higher than traditional tools, with optimized processing cycles;
• Excellent heat dissipation: Avoids overheating damage to workpieces during grinding, ensuring the performance of blade materials;
• Strong wear resistance: Service life is several times that of ordinary domestic polishing wheels, extended to 3 times that of traditional products;
• High cleanliness: Effectively reduces dust and chip generation, improves operating environment, and enhances processing stability.
Contribution Dimension | Specific Performance |
Surface Quality Improvement | Precisely removes burrs, scratches, and other defects on blade edges, forms uniform grinding lines, significantly reduces the risk of over-cutting and rework rate, and ensures that blade aerodynamic performance meets design standards |
Processing Efficiency Optimization | Fast cutting speed reduces tool change downtime; combined with long service life, it significantly improves overall production efficiency |
Domestic Substitution Value | Performance is comparable to imported similar products (e.g., 3M EXL series), breaks dependence on imported tools, reduces procurement costs for aviation manufacturing enterprises, and ensures supply chain security |
Process Adaptability | Covers grinding of complex blade parts such as blade body, root, tip, tenon, and flange; compatible with automated equipment and manual operation, meeting the high-precision processing requirements of aero-engine blades |
1. Blade Deburring: Efficiently removes burrs from key areas prone to burr generation (such as tenons and flanges) without damaging the workpiece surface;
2. Surface Polishing and Conditioning: Repairs blade surface scratches, precisely controls surface roughness, and ensures compliance with aerodynamic performance standards;
3. Edge Treatment: Performs rounding and smoothing on inlet and outlet edges to reduce stress concentration and improve blade fatigue life.
The promotion and application of Pengyu EXL Winding Wheel have driven the domestic upgrading of China's aircraft blade grinding technology. It provides a high-performance, low-cost, and high-stability grinding solution for domestic aero-turbine manufacturing, helping to enhance the core competitiveness and autonomy of Interational and domestic aviation manufacturing industry.
