Professional CNC Small Gear Machining Services

AOOM Technology delivers precision CNC small gear machining for miniature gear profiles under 50mm diameter used in automotive actuator systems, aerospace flight controls, robotics, and medical instrumentation. Our 5-axis CNC systems produce spur, helical, bevel, and worm gears with micron-level tooth accuracy and complete dimensional inspection reports, backed by gear measurement system (GMS) verification for every critical parameter.

Key Technical Specifications

• Gear tooth accuracy: DIN Class 5 to 7 / AGMA Quality Q9 to Q11 depending on material, geometry, and heat treatment
• Diameter range: 3mm to 50mm; modules M0.3 to M2.0; pressure angles 14.5°, 20°, and 25°
• Materials: 4140 and 4340 alloy steel, stainless steel 17-4PH and 303, aluminum 7075-T6, brass C360, Delrin, and PEEK
• Heat treatment options: carburizing and case hardening, through-hardening, induction hardening of tooth flanks, and cryogenic stress relief for dimensional stability
• Full gear metrology: tooth profile (involute), lead (helix), single- and adjacent-pitch, total composite error, and runout using dedicated CNC gear measurement systems
• Rapid prototyping: 72-hour turnaround for single-piece gear samples and first-article inspection reports

Applications

Our small gears are integral to automotive actuator mechanisms such as power seat adjuster drives, mirror positioning gear trains, and throttle control actuators; aerospace trim control servo gear boxes and flap actuator planetary stages; robotic joint harmonic drive input stages and precision positioning stage worm-wheels for semiconductor wafer handling; medical infusion pump peristaltic drive gears, endoscopic surgical stapler rack-and-pinion mechanisms, and dental handpiece reduction gear sets; and industrial encoder hollow-shaft assemblies and flow meter turbine drives where low inertia and high reliability are paramount.

Quality Assurance

Every cnc small gear machining order from AOOM Technology is manufactured under a comprehensive quality management system certified to ISO 9001:2015. We employ coordinate measuring machines (CMM) for full dimensional verification, First Article Inspection (FAI) per AS9102 for new production runs, and in-process statistical process control (SPC) to maintain consistent quality across all batches. Material certifications, dimensional reports, and compliance documentation are provided with every shipment.
