6. Key Precautions for CNC Machining Electric Curtain Prototypes
To ensure quality and efficiency, observe these precautions:
- Präzisionskontrolle: Strictly control track teeth accuracy (± 0,02 mm) and gear coaxiality (≤0.03mm) to avoid jamming; Reserve ±0.1mm tolerance for mounting holes to facilitate assembly.
- Material Adaptation: Aluminiumlegierung: Use cutting fluid to avoid overheating deformation; Pom: Control cutting speed (8000-12000 Drehzahl) zum Schmelzen zu verhindern; ABS: Dry before machining to avoid bubbles.
- Kostenoptimierung: CNC machining is ideal for ≤100 units; für die Massenproduktion (>1000 units), switch to injection molding (ABS/PC parts) und Extrusion (aluminum alloy tracks) to reduce cost by 50-60%. Simplify track design (Z.B., replace complex curves with straight sections) to shorten toolpaths.
- Safety Operation: Wear safety glasses/gloves during machining; Use fume extractors for painting/anodization; Ground equipment to prevent electric shock when testing control modules.
Standpunkt der Yigu -Technologie
Bei Yigu Technology, Wir glauben CNC machining is the core to developing reliable electric curtain prototypes. It enables precise control of critical transmission components—from track inner teeth (±0.02mm accuracy) to gear coaxiality (≤0.03mm)—and supports rapid iteration, which is vital for balancing functionality (smooth operation, low noise) und Haltbarkeit (load-bearing, Korrosionsbeständigkeit) in electric curtains. When producing these prototypes, we focus on two core aspects: material-function matching (aluminum alloy for load-bearing tracks, POM for low-noise gears) und Prozessoptimierung (spiral interpolation for tooth accuracy, multi-point fixtures for long tracks). By integrating strict quality control from design to testing, we help clients shorten development cycles by 25-30% and mitigate mass production risks. Blick nach vorn, we will apply AI-driven parameter optimization to CNC machining, further improving efficiency while maintaining ±0.02mm precision for more refined electric curtain prototypes.
