Precision Micro CNC Milling For Aircraft Landing Gear Components And Hydraulic System Joints
Advantages of Precision Milling
High Precision: CNC milling machines can achieve extremely high precision, often reaching tolerances of ±0.001 inches or even tighter. This level of accuracy is crucial for components in the electronics industry, such as printed circuit boards (PCBs) and microchips, where even the slightest deviation can lead to malfunction.
Complex Geometries: The ability to produce intricate and complex shapes is another advantage. CNC milling can create detailed features, such as fine grooves, holes, and contours, which are often required in electronic components. This flexibility in design is essential for the miniaturization trend in the electronics industry.
Surface Finish: Milling can provide a smooth and consistent surface finish, which is important for electronic parts that require precise mating surfaces or good heat dissipation. A well-finished surface can also enhance the overall performance and reliability of electronic devices.
Material Compatibility: CNC milling is compatible with a wide range of materials used in the electronics industry, including metals like aluminum and copper, as well as various plastics and composites. This versatility allows manufacturers to choose the most suitable material for each specific application.
Reproducibility: Once a milling program is set up, it can be repeated with high precision, ensuring that each part produced is identical to the last. This is particularly important for mass production of electronic components, where consistency is key.

What Surface Treatment can Be Used?
Metal milling parts can undergo various surface treatments, including mechanical treatment (polishing, sandblasting), chemical treatment (pickling, passivation), electrochemical treatment (electroplating, anodizing), coating treatment (spraying, electrophoretic coating), heat treatment (surface hardening), as well as laser treatment and PVD/CVD coating.
The Difference Between Turning and Milling
| Characteristic | Milling | Turning |
| Suitible | Suitable for processing non rotational symmetric parts such as planes, grooves, holes, and complex surfaces. | Suitable for processing cylindrical, conical, and other rotationally symmetric parts |
| Process | Tool rotation, workpiece fixation or movement | The workpiece rotates and the tool moves axially or radially. |
| Precision | High precision, but may be slightly lower than turning | High precision, suitable for micrometer level size control. |
| Surface | The surface quality depends on the tool and process parameters, usually slightly lower than turning. | High surface smoothness, suitable for parts with high surface quality requirements. |
| Material removal rate | The material removal rate is low, but it is suitable for fine processing of complex shapes. | The material removal rate is high, suitable for quickly removing large amounts of materials |
| Flexibility | Suitable for processing complex shapes with high flexibility. | Suitable for mass production of rotational symmetric parts, with low flexibility. |
