Key CNC Demands for Automotive Precision Parts
▎Lightweight and energy efficiency improvement
- Material upgrade: aluminum alloy (40% weight reduction), magnesium alloy, carbon fiber composite material (CFRP) precision molding, used for body structure, battery tray, etc.
- Miniaturized design: The fuel injection system nozzle aperture is ≤0.1mm, relying on micro-electrodischarge machining (μEDM).
▎Electrification and intelligent transformation
-Electric drive system: The motor rotor shaft accuracy must reach IT4 level (roundness ≤ 2μm), relying on ultra-precision grinding technology.
-Sensor components: The roughness of the laser radar optical mirror surface Ra ≤ 0.02μm, requiring single-point diamond turning (SPDT) technology.
▎Large-scale production and cost control
- High-efficiency processing: cylinder block/cylinder head production line cycle ≤ 60 seconds, relying on modular fixtures and high-speed machining centers (HSM).
- Zero defect management: CPK ≥ 1.67 for key parts (such as gearbox gears), and real-time correction through online detection (such as laser scanning).
