Professional CNC Spline Machining Services

AOOM Technology brings over 15 years of precision manufacturing expertise to every cnc spline machining project. As an ISO 9001:2015-certified facility operating 50+ advanced CNC machining centers in Shenzhen, China, we combine state-of-the-art equipment with experienced engineers to deliver components that meet the most demanding specifications. From initial design consultation through final quality validation, our streamlined workflows ensure competitive pricing, reliable lead times, and consistent repeatability across prototype and full-scale production runs.

Key Technical Specifications

• Dimensional accuracy maintained within ±0.005 mm for involute, straight-sided, and serrated spline profiles
• Process capabilities: precision hobbing, CNC milling with form cutters, broaching for internal splines, and finish grinding
• Material expertise: alloy steel (4140, 8620), stainless steel, aluminum, titanium, and engineered composites
• Surface treatments: carburizing, nitriding, induction hardening, and hard chrome plating for extended wear life
• Full inspection suite: spline gauging, CMM tooth profile analysis, and runout verification

Applications

Precision-machined components from AOOM Technology serve critical functions across a wide range of industries, including:

• Power transmission shafts and splined couplings in heavy industrial equipment
• Automotive drivetrain components including CV joints and transmission shafts
• Aerospace actuator splines and flight surface control mechanisms
• Agricultural machinery drivetrain splines for high-torque transfer
• Robotic joint splines requiring zero-backlash engagement and long service life

Quality Assurance

Every component we produce undergoes rigorous quality assurance protocols aligned with ISO 9001:2015 standards. Our inspection workflow includes first-article inspection (FAI) with full dimensional reports, in-process CMM sampling at defined intervals, material certification and traceability documentation, and surface finish verification against specified Ra requirements. For complex geometries and tight-tolerance features, we employ 3D scanning against the original CAD model to validate conformance before shipment. This systematic approach ensures that every part leaving our facility meets or exceeds the engineering requirements.
