Aluminum alloy nut with slot adjustment piece - precision CNC processed hardware
Aerospace Field
Practical Products
Supporting nuts for aircraft fuselage structural components, engine block fixing nuts, satellite bracket locking nuts, aviation instrument fastening nuts, and UAV frame connection nuts.
CNC Production & Processing Features
High-strength and lightweight materials such as titanium alloy, superalloy, and 17-4PH stainless steel are adopted.
CNC machining achieves high-precision internal threads, special-shaped profiles, anti-loosening slots, and stepped structures, with coaxiality and flatness controlled within ±0.01 mm.
Multi-process one-step forming is supported to ensure batch consistency and stability.
Surfaces require anti-corrosion treatments such as passivation and anodizing to meet aerospace-grade weather resistance requirements, and internal thread precision must reach grade 6H or higher.
Product Performance Advantages
Light weight, high strength, vibration resistance, fatigue resistance, high and low temperature resistance, and corrosion resistance.
Internal threads are smooth without jamming, fit tightly with bolts, and do not slip or disengage after repeated assembly and disassembly.
No failure under long-term high-altitude / extreme environments, with extremely high locking reliability.
Adapts to the core “zero-failure” demand of aviation equipment and ensures stable component connection.
Common CNC Machining Problems & Key Points
Material Processing Difficulties
Titanium alloys and superalloys feature high hardness and toughness. Internal thread processing is prone to tool wear and chipping.
Hard alloy coated taps shall be used, with reduced cutting speed and increased feed rate to avoid built-up edge and ensure complete thread profile.
Precision Control Issues
Internal thread processing is prone to pitch deviation and irregular thread profile; deep-hole nuts may have inclined hole walls and substandard surface roughness.
Center drill positioning, step-by-step drilling + tapping, and cutting fluid cooling shall be adopted to reduce thermal deformation and ensure compatibility between internal threads and bolts.
Thread Processing Problems
Fine-pitch internal threads are prone to thread slipping and crest burrs.
Thread lead error must be strictly controlled, and go/no-go gauge inspection shall be performed after tapping to avoid loose fitting with bolts caused by insufficient thread precision, which impairs locking effect.
Surface Treatment Problems
Scratches and burrs easily appear on machined surfaces, and iron chips tend to remain in internal threads.
Finishing and chamfering processes shall be added at the final stage of CNC machining to remove residual impurities in internal threads, prevent burrs from affecting assembly safety, and ensure uniform surface treatment.
