Aluminium CNC Cutting Service

We are a manufacturing company specializing in CNC processing, and have long provided high-quality aluminum CNC cutting services (aluminum CNC cutting service) to global customers. Relying on advanced high-speed machining centers, rich programming experience and a complete testing system, we are able to achieve cutting of various aluminum alloy parts with complex shapes and high precision requirements.

Our aluminum CNC cutting service supports a variety of aluminum alloy materials (such as 6061, 7075, 5083, etc.), and can process thicknesses from 0.5mm to 100mm, suitable for structural parts, housing parts and radiators in industries such as automation equipment, aviation parts, consumer electronics, and medical equipment.

Processing case: Overcoming the warping problem of 7075 thin-walled aluminum alloy bracket
We once processed a high-strength thin-walled aluminum bracket for a model aircraft customer. The material is 7075-T6 aluminum alloy, and the requirements are as follows:

The part size is 120mm × 60mm × 8mm, and there are multiple special-shaped lightweight holes in the middle

The wall thickness is only 1.0mm, and countersunk holes need to be processed at both ends. The flatness of the mounting surface is required to be ≤0.02mm

The surface needs to be sandblasted and anodized, and there must be no deformation, burrs or knife marks

Difficulty analysis:
7075 aluminum has high strength but poor ductility. It is easy to heat up locally during cutting to produce internal stress, causing the part to warp or twist after release;

Thin-walled structures are very likely to produce vibration and resonance during cutting, affecting the surface finish and hole accuracy;

If the deformation is not controlled after processing, the stress will be released again during the anodizing process, resulting in dimensional instability.

Use high-speed spindle (20000rpm) + small feed processing strategy to reduce heat concentration and cutting load;
Use special vacuum adsorption fixture to fix the workpiece to prevent vibration and offset;

Use multi-stage shallow cutting + reverse tool path for finishing, which is completed in partitions to ensure balanced stress release;

After processing, natural aging treatment is carried out for 48 hours before surface treatment to control deformation accumulation;

Before leaving the factory, three-coordinate detection of key holes and countersunk planes is performed to ensure correct installation and matching.

Through this series of control measures, the dimensional accuracy and appearance of parts meet the requirements of aviation assembly.
