Aluminum CNC Processing
Aluminum CNC processing is a precision manufacturing technology that uses CNC machines to process aluminum and its alloys. Thanks to aluminum’s lightweight, corrosion-resistant and high-strength properties, it is widely used in high-end industries, with CNC processing ensuring high precision, consistency and efficiency for custom components.
Processing Process
- Design && Programming: Convert customer drawings or requirements into 3D models and CNC programs, specifying key processing parameters for precise production.
- Material Preparation && Clamping: Select suitable aluminum alloys (e.g., 6061, 7075), cut to size and firmly clamp on the machine workbench to avoid processing displacement.
- Precision Machining: The CNC machine automatically performs milling, drilling, tapping and other operations, ensuring stability and accuracy via high-speed spindle and precision guide rail.
- Post-Processing && Inspection: Conduct deburring, polishing or anodizing, then inspect size and precision with professional equipment to meet requirements.
Processing Difficulties
- Material Softness && Chip Adhesion: Aluminum is soft, leading to chip adhesion on tools; solved by special carbide tools and cutting fluid.
- Deformation Control: Thermal and clamping deformation is minimized by optimizing processing parameters and clamping methods.
- High-Precision Requirements: High-end industry components require ultra-high precision (±0.005mm), demanding high-quality machines, tools and programming.
- Surface Quality Control: Avoid scratches and uneven marks via high-speed cutting and enhanced post-processing.
Application Scenarios
- Aerospace Industry: Lightweight, high-precision components like brackets and engine parts.

7075 Aluminum CNC Machining
7075 aluminum is a premium aerospace-grade alloy with high tensile strength, superior hardness, good fatigue resistance and lightweight performance. It is the preferred material for high-load, high-precision structural components in high-end industries.
Machining Precision
We can stably control machining tolerance from ±0.05 mm for standard parts to ±0.005 mm for ultra-precision applications. The conventional guaranteed precision for most custom components is ±0.02 mm ~ ±0.03 mm.
Processing Difficulties && Our Solutions
Difficulty 1: Dimensional Deformation — 7075 has high hardness and internal stress, which easily causes deformation due to cutting heat and clamping force during machining.
Solution: Adopt multi-step cutting (rough machining + semi-finishing + finishing) to release internal stress step by step; optimize clamping force and use heat dissipation cutting fluid to reduce thermal deformation.
Difficulty 2: Tool Wear — Its high hardness leads to fast tool wear, increasing processing costs and affecting efficiency.
Solution: Use high-hardness carbide tools, adjust cutting speed and feed rate reasonably, and conduct regular tool inspection and replacement to ensure processing efficiency and precision.
Application

6061 Aluminum
6061 Aluminum CNC Machining
6061 aluminum is the most widely used general-purpose aluminum alloy, featuring good toughness, excellent corrosion resistance, easy welding and perfect machinability. It balances cost, performance and appearance, becoming the mainstream material for conventional CNC custom parts.
Machining Precision
Stable tolerance ranges from ±0.05mm to ±0.10mm for standard structural parts; precision components can reach ±0.02mm ~ ±0.03mm with optimized processes.
Processing Difficulties && Our Solutions
Difficulty 1: Chip Adhesion — 6061 is relatively soft, so chips are easy to stick to the tool head during high-speed machining, affecting surface finish and precision.
Solution: Adopt carbide cutting tools with special coating, match with high-efficiency cutting fluid, and optimize feed rate to reduce friction and chip adhesion, ensuring smooth cutting.
Difficulty 2: Surface Scratches — The soft surface of 6061 is prone to scratches during clamping and processing, affecting appearance.
Solution: Use soft clamping fixtures (rubber or plastic gaskets) to avoid direct contact damage; clean the workbench and tools regularly, and conduct post-processing polishing if needed.
Application
Widely used in automation equipment, automotive parts, electronic enclosures, daily hardware, fixtures and general mechanical structural components.
