Aluminum CNC Cutting Services

We are a professional CNC precision processing company, dedicated to the efficient Aluminum CNC Cutting Services of aluminum alloy parts for a long time, with more than 16 years of industry experience, serving more than 100 customers worldwide. With advanced CNC machining centers and strict quality systems, we can quickly deliver precision and complex aluminum parts to help customers shorten the development cycle.

Our Aluminum CNC Cutting Services covers services from prototype development, small batch trial production to mass manufacturing, and supports customers to provide 2D drawings or 3D model data for customized processing. The processing materials mainly include 6061, 7075, 2024, 5052 and other aluminum alloys, and provide a variety of post-processing options, such as anodizing, electroplating, sandblasting, laser engraving, etc., to meet the application needs of different fields and industries.

Deformation control and process breakthrough of thin-walled deep-cavity aluminum parts

We once undertook a core shell part for a UAV customer. The material is aviation-grade 7075-T6 aluminum alloy. The structure includes multiple deep cavities, multi-step slots and ultra-thin wall areas. The thinnest part is only 1.2mm, and the overall length is 140mm. The difficulties are concentrated on:

• Multiple inner cavity design, complex cutting path, easy to accumulate heat;
• Uneven wall thickness, asymmetric structure, very easy to produce stress concentration deformation during processing;
• The finished product needs to achieve ±0.01mm accuracy, the bottom surface flatness ≤0.03mm, and the surface needs to be within Ra1.6.

1. Pretreatment stage: rough machining of the blank is naturally aged for 48 hours to release the internal stress of the material;

2. Fixture design: vacuum adsorption fixtures are used in combination with local support to avoid the compression and deformation of thin-walled areas by traditional mechanical fixtures;

3. Rough-semi-finish-finish three-level processing path: adopt layer-by-layer step-by-step cutting, leave enough margin, and prevent the superposition of processing stress;

4. Tool path optimization: select high-speed low-feed + fillet interpolation process in programming to avoid tool marks and micro-cracks;

5. Finishing tool path process: use R tool to slowly circle tool path on key steps and joints to ensure smoothness and consistency;

6. Quality inspection: CMM three-coordinate measurement of 50+ key dimensions is used for each batch, and the whole process is archived for easy traceability.

In the end, the delivery accuracy of this project far exceeded customer expectations, with a yield rate of over 99.5%, helping customers to smoothly advance product finalization and small-batch trial production
