Professional CNC Precision Small Parts Machining Services

AOOM Technology, a trusted CNC machining service provider, specializes in the precision fabrication of miniature components used across aerospace, medical, and electronics industries. Our advanced 5-axis machining centers and temperature-controlled workshop enable consistent micron-level accuracy for even the most demanding small-part geometries. We understand that when it comes to small parts, even a few microns of deviation can compromise assembly fit and functional performance, which is why every operation is carefully planned and executed with precision.

Key Technical Specifications

• High-speed spindles up to 50,000 RPM for clean micro-cutting of miniature features
• Tolerance capability of ±0.005 mm consistently achieved on complex small parts
• Surface finish down to Ra 0.4 μm verified per ISO 4288 standards
• Laser-assisted tool measurement and in-process vision inspection systems for real-time quality feedback

• Medical devices: surgical instrument components, micro-implant prototypes, and dental tool parts requiring biocompatibility
• Electronics: precision connectors, heat sink micro-fins, RF waveguide components, and enclosure parts
• Optics: lens mounts, aperture blade assemblies, and alignment fixtures requiring sub-micron positioning accuracy
• Automotive: fuel injector nozzle components, turbocharger variable vane assemblies, and EGR system precision parts
• Industrial instrumentation: pressure sensor bodies, flow meter components, and pneumatic valve actuators

Quality Assurance

At AOOM Technology, quality is integrated into every stage of production from the initial material receiving through final packaging. Our ISO 9001:2015 certified quality management system governs all processes and is subject to regular internal and external audits. Every production run begins with a comprehensive first-article inspection (FAI) using coordinate measuring machines (CMM) with repeatability as tight as 0.5 μm. Dimensional data from the first article is compared against the engineering drawing in every axis and feature, and the results are documented in a full inspection report. In-process inspection at defined frequency ensures that any dimensional drift is detected and corrected in real time before non-conforming parts can be produced. Surface roughness is verified per ISO 4288 standards using calibrated profilometers, and material certifications provide full traceability from mill source to finished part. We also perform capability studies (Cpk analysis) on critical features to guarantee process stability before transitioning to volume production. All inspection equipment is calibrated on a scheduled basis with NIST-traceable standards, and our quality team maintains detailed records for every order to support your audit requirements.
