A Certain Blade Grinding Automation Cell

• Core Requirements: The client requires precision grinding of multiple positions on XX blades, including the tenon teeth, tenon bottom surface, leading/trailing edges, platform areas (concave/convex sides), and blade tip. The requirement also includes the integration of automatic batch marking, projection inspection, CMM inspection, and unified control of full-process data.
• Existing Pain Points: The original machining mode suffered from issues such as high investment costs, low grinding efficiency, and long debugging cycles. Additionally, part clamping was cumbersome, and quality could not be managed via a closed loop, making it difficult to meet the demands of mass production and high-precision R&D. There was an urgent need for an integrated automated grinding solution.

• Core Machining Equipment: Custom-configured with 4 CNC creep-feed grinding machines (3-coordinate grinder + 2-axis rotary table, non-5-axis linkage) and 1 five-axis milling center. Innovatively adopting a "3-axis + rotary table" control mode, it precisely covers multi-position grinding and milling, significantly reducing equipment procurement costs while ensuring precision.
• Automated Logistics: Equipped with a 6-axis articulated robot (mounted on a 7th axis linear rail), a high-precision zero-point positioning system, CHINAF custom fixture libraries, and loading/unloading stations. This realizes full-process automation for blade transfer, clamping, loading, and unloading, achieving multi-station machining with a single clamping and eliminating manual intervention errors.
• Inspection and Support: Integrates a CMM, a tenon profile measurement system, an identification system, and automatic marking equipment to realize automatic projection inspection, full-dimension CMM inspection, and automatic batch number marking. Meanwhile, CMM data is utilized for machining compensation and pose adjustment, constructing a full closed-loop quality traceability system.
• Integration and Assurance: Features the CHINAF cleaning system, safety protection system, custom fixtures, and the self-developed PCS Production Manufacturing Management Software. By integrating digital twin technology with turnkey service, it achieves seamless data integration and unified control over the entire cell, completing project implementation via a one-stop solution.

• Significant Cost Reduction and Efficiency Increase: The innovative "3-axis + rotary table" configuration replaces traditional high-cost 5-axis linkage, maximizing cost-effectiveness. Utilizing the company's self-developed HF-DTwins® digital twin technology shortens debugging and R&D cycles, while multi-station integrated machining increases overall efficiency by 10%.
• Precise and Controllable Quality: Relying on the CMM to achieve machining compensation and full closed-loop processing, combined with multiple high-precision inspection systems, ensures comprehensive assurance of blade grinding precision and consistency, with product qualification rates far exceeding expectations.
• Intelligent Digital Control: Through the PCS system, full equipment data collection and centralized control are realized, breaking down information silos; the deep synergy between digital twins and automation drives the upgrade of production towards intelligence and standardization.
• Worry-Free and Efficient Implementation: Providing a full-process turnkey service covering all aspects from fixture design and equipment debugging to part machining eliminates the need for multi-party coordination by the client, rapidly realizing capacity upgrading and digital transformation.
