Quality assurance is integral to our process. Post-machining, every spiral bevel gear set undergoes rigorous inspection for gear accuracy using German Zeiss CMMs (Coordinate Measuring Machines) and dedicated gear measuring centers. We verify critical parameters including:
- Tooth Profile & Lead Accuracy: Ensuring the curvature matches design specs for optimal contact patterns.
- Runout & Pitch Variation: Guaranteeing concentricity and consistent tooth spacing to minimize vibration.
- Surface Hardness & Case Depth: We conduct random Rockwell hardness tests and metallurgical sampling to confirm our heat treatment (carburizing/nitriding) meets the required 58-62 HRC surface hardness with a tough core.
- Contact Pattern Test: Before shipment, we perform a “blueprint” contact test on assembled pairs to ensure the load is distributed evenly across the tooth face. All inspections comply with AGMA 2009 and ISO 18653 standards, and we provide a full Inspection Report with each shipment for your records.
