Capability & Engineering Review
Product Overview & Engineering Specifications
This product showcases Dongguan Ruibo’s large-scale OEM contract manufacturing capabilities for high-precision Multi-Hole Flanged Hubs and Stepped Precision Bushings supplied to Tier-1 automotive and industrial automation leaders.
Machined from premium alloy and stainless steel bars on high-speed twin-spindle turn-mill multitasking centers, all turning, radial drilling, and cross-tapping operations are completed in a single setup. These components offer exceptional dynamic balance, high concentricity, and superior fatigue resistance under high torque and continuous vibration.
Core Manufacturing Advantages & Quality Assurance
Turn-Mill Multitasking with Sub-Micron Consistency
Outer diameter turning, stepped bore boring, and multiple radial/flange tapped holes are machined in one unified clamping cycle. This eliminates indexing errors, achieving CpK ≥ 1.67 for large-volume runs.
Automated Micro-Deburring & Cleanliness Control
Intersecting holes and thread entrances undergo dedicated deburring and multi-stage ultrasonic degreasing, ensuring zero metal burrs or chips remain to damage seals or bearings in downstream automotive assemblies.
IATF 16949 Certified Quality Inspection
Equipped with ZEISS CMMs, optical profile projectors, thread gages, and roughness testers. Full First Article Inspection (FAI), in-process statistical process control (IPQC), and final batch verification (FQC) guarantee 100% compliance.
Scalable Production & Protective Export Packaging
Backed by dozens of CNC multi-axis centers with robotic loading, supporting monthly capacities from thousands to hundreds of thousands of units. Packed in custom anti-collision trays and treated with anti-rust oil for long-distance ocean freight.
Industrial Applications
Automotive & Powertrain: Drive shaft flange adapters, steering column bushings, torque converter hubs, suspension link mounts.
Industrial Automation & Robotics: High-rigidity servo couplings, harmonic drive adapter sleeves, rotary indexing hubs.
Hydraulics & Heavy Equipment: High-pressure pump flanges, tensioner pulleys, multi-port manifold bushings.
