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. |
