Custom Nylon Parts CNC Milling

Some milling machines will be more appropriate than others, depending on various factors. The complexity of the CNC milling operations will be dependent on the design of the final part. The more structurally important and high-end the part or product is, the more complex the design may need to be.

For example, a more complex machine may need to be used for intricate designs requiring high precision, such as medical or aerospace components. This is to achieve the final design, finish, and aesthetic.

Basic parts that are machined for more general use may not require such high precision or high-quality finish. Complex and intricate designs will typically require additional milling.

Often milling machines utilise either 3, 4 or 5 axes.

For simpler parts, fewer axes are needed to achieve the final design. Simple geometries can generally utilise a 3-axis milling machine. They are easy to program and operate, achieving excellent accuracy at a low cost.

The cutting tools are attached to a spindle that works on three linear axes. They can spin at thousands of RPM, meaning even the sturdiest of materials can be cut through with ease and accuracy.

3-Axis machines are the most common variety of a CNC mill and can cut vertically (Z-axis) and in an X and Y direction.

However, it' s usually not possible to machine undercuts with 3-axis CNC mills. These are features that cannot be accessed with a standard end mill. This means that more complex designs may require a more complex milling machine.

The 4-axis milling machine is more sophisticated, with the additional ability to rotate on the X-axis (similar to a lathe).

5-Axis milling machines include rotation in both the X and Y-axis. They are the most complete milling machines available and are implemented for highly complex designs such as medical devices and implants for the medical industry, impellers and aerospace structures.
