3.2 Usinage des détails clés
Critical details directly affect the prototype’s functionality and pet safety:
- Sealing Groove Machining: Control groove width (2MM) and depth (1MM) with tolerance ±0.05mm; Ensure groove uniformity (no depth deviation >0.03mm) to fit silicone gaskets (étanche, IPX7 standard).
- Water Level Mark Engraving: Use laser engraving on acrylic water tanks to mark “Max.” (limite supérieure) et “Min.” (limite inférieure) lines; Engraving depth 0.2-0.3mm (clear visibility, pas de fuite d'eau).
- Pump Mounting Hole Machining: Ensure hole coaxiality (≤0,05 mm) with water pipe interface; Add positioning boss (height 2mm) to fix the pump (prevent vibration displacement).
- Edge Chamfering: All components in contact with pets (water tank edges, base corners) must be chamfered (R1mm) or rounded (R2mm) to avoid scratching pets’ mouths or paws.
3.3 Inspection de la qualité de l'usinage
Conduct in-process checks to ensure quality:

Follow this sequence to avoid errors:
- Vérification avant assemblage: Inspect all parts for defects (pas de rayures, dimensional deviation ≤0.1mm); Prepare auxiliary materials (silicone gaskets, non-toxic glue, food-grade hoses, vis).
- Component Installation:
- Water Tank Assembly: Place silicone gasket in the tank’s sealing groove; Fix tank to base with M3 screws (torque 0.8-1N·m, even force to avoid cracking acrylic).
- Pump & Filter Installation: Mount pump on the support (snap-fit or screws); Connect pump to water pipe connector (use food-grade hose); Install filter element in the filter tank (snap-fit, ensure tight seal).
- Pipeline Connection: Connect water pipe from pump to tank inlet, and from tank outlet to filter tank; Check for pipeline kinks (ensure smooth water flow).

6. Key Precautions for CNC Machining Pet Water Dispenser Prototypes
Pour assurer la qualité, sécurité, et efficacité, observe these precautions:
- Safety Priority: All materials must be non-toxic (pass RoHS, FDA food-grade certifications); Avoid sharp edges (chamfer all pet-contact parts to R1mm); Stainless steel parts must be corrosion-resistant (prevent rust from contaminating water).
- Contrôle de précision: Sealing groove tolerance ±0.05mm (ensures waterproofing); Pump hole coaxiality ≤0.05mm (prevents vibration noise); Acrylic parts reserve ±0.1mm shrinkage (avoids post-machining size deviation).
- Optimisation des coûts: CNC machining is ideal for ≤100 units; Pour la production de masse (>1000 units), switch to injection molding (ABS/acrylic) to reduce cost by 50-60%. Simplify complex curves (Par exemple, replace irregular tank shapes with regular cylinders) to shorten toolpaths.
- Protection de l'environnement: Use non-toxic, biodegradable coolants for machining; Dispose of plastic/metal waste in accordance with environmental regulations (recycle stainless steel scraps).
Point de vue de la technologie Yigu
À la technologie Yigu, nous croyons CNC machining is the core to developing safe and user-friendly pet water dispenser prototypes. It enables precise control of critical structures—from pet-safe edge chamfers (R1mm) to waterproof sealing grooves (± 0,05 mm)—and supports rapid iteration, which is vital for balancing functionality (circulation, filtration) and pet safety (non-toxicity, pas de bords tranchants). When producing these prototypes, we focus on two core aspects: material-safety matching (acrylic for transparent tanks, food-grade stainless steel for connectors) et l'optimisation du processus (vacuum adsorption for acrylic, low-speed machining for stainless steel). By integrating strict quality control from design to testing, we help clients shorten development cycles by 20-25% and mitigate mass production risks. Regarder vers l'avenir, we will apply AI-driven parameter optimization to CNC machining, further improving efficiency while maintaining ±0.03mm precision for safer, more reliable pet water dispenser prototypes.
