CNC Machining Center Precision Manufacturing Process for Service Robot Anti Collision Bumper Guide Posts With High Preci
2025-09-09
The manufacturing process of anti-collision bumper guide posts utilizes multi-axis CNC precision machining centers and automated production lines. Through strict process control and quality inspection, each guide post meets the high reliability requirements of service robots in various application scenarios. The machining process incorporates precision manufacturing technologies from the aerospace industry and polymer material molding processes.
The manufacturing process of anti-collision bumper guide posts consists of the following key stages:
Selection of aviation-grade aluminum alloy bar stock (AA6061-T6) and engineering polymer raw materials, followed by material composition testing and mechanical performance testing. Aluminum alloy materials undergo preheat treatment (350℃*2h) to eliminate internal stress and improve material stability.
Aluminum components are precision machined on five-axis CNC machining centers:
- Rough Machining Stage: Using φ6mm carbide end mills at 4800rpm spindle speed and 800mm/min feed rate to remove most excess material
- Semi-Finishing Stage: Using φ4mm ball nose cutters at 6000rpm spindle speed and 600mm/min feed rate for contour forming
- Finishing Stage: Using φ2mm precision mills at 8000rpm spindle speed and 400mm/min feed rate to complete final forming, ensuring surface roughness Ra≤0.8μm
Completed aluminum components undergo:
- Anodizing Treatment: Hard anodizing in sulfuric acid electrolyte (concentration 180g/L, temperature 20℃) to form 25-30μm thick oxide film
- Sealing Treatment: Soaking in hot pure water (95℃) for 30 minutes to improve corrosion and wear resistance of the oxide film
- Polymer Component Injection Molding: Engineering polymer POM is formed into anti-collision buffer components in injection molding machines (barrel temperature 185-205℃, injection pressure 80MPa)
Each guide post undergoes strict inspection:
- Dimensional Accuracy Inspection: Using coordinate measuring machines (CMM) to check critical dimensions, ensuring tolerances within ±0.01mm
- Surface Quality Inspection: Microscopic examination of surface defects and roughness
- Performance Testing: Impact tests (50J impact energy) and fatigue tests (1 million cycles)
Automated assembly lines complete precision assembly of metal and polymer components, with laser marking for product traceability, followed by anti-static packaging and pre-shipment inspection.
