Product Background
As the automotive industry evolves toward electrification and high-performance engineering, the demand for complex, non-standard precision parts has reached unprecedented levels. Our client required a specialized component with intricate curved surfaces and demanding aesthetic requirements that traditional 3-axis machining could not achieve without excessive fixturing and cumulative errors.
The challenge lay in the material’s extreme hardness and the dual requirement for structural durability and a flawless surface finish. Previous manufacturing attempts resulted in inconsistent dimensions and tool vibration marks, compromising the part’s performance in high-stress automotive environments.
Technical Challenges
Extreme Geometric Complexity: The part features multi-faceted curved surfaces that require synchronized movement across five axes to eliminate tool marks and ensure seamless contours.
High Material Hardness: The workpiece material is exceptionally rigid, leading to rapid tool wear and potential deformation during high-speed cutting.
Stringent Aesthetic & Precision Standards: Maintaining a ±0.02mm tolerance while achieving a high-gloss finish requires sophisticated vibration control and optimized cutting parameters.
Integrated Thermal Processing: Achieving the final hardness specification requires a precise post-machining heat treatment without warping the high-precision dimensions.
The REBAN Solution
1. Advanced 5-Axis Synchronous Machining
REBAN utilized high-end 5-axis machining centers to complete multi-sided and complex curved surface processing in a single setup. This significantly reduced clamping errors, eliminated the need for specialized manual fixtures, and lowered overall production costs while increasing structural accuracy.
2. Optimized “Rough-to-Finish” Strategy
To manage the high-hardness material, our engineering team implemented a two-stage machining process:
Initial Roughing: Rapid material removal to reach near-net shape while managing heat dissipation.
Precision Finishing: High-speed, low-vibration finishing passes to ensure both dimensional precision and a superior “mirror-like” surface finish.
3. Precision Heat Treatment Integration
Following the CNC process, parts underwent a strictly controlled thermal treatment. By calculating material expansion and contraction rates during the design phase, we ensured the components reached the required HRC hardness while staying within the final ±0.02mm tolerance window.
4. Expert Process Planning (DFM)
From initial concept to mass production, the REBAN engineering team formulated a comprehensive manufacturing plan. This proactive “Advanced Product Quality Planning” (APQP) approach identified potential bottlenecks early, ensuring a zero-defect transition from prototype to final delivery.
Results & Customer Benefits
Dimensional Accuracy: Successfully maintained a consistent ±0.02mm tolerance across all critical dimensions.
Superior Surface Quality: Met the highest automotive aesthetic standards, eliminating the need for secondary manual grinding.
Enhanced Durability: Integrated heat treatment provided the exact hardness required for high-stress automotive applications.
