CNC machining is a plastic manufacturing process involving cutting tools mounted on a CNC machine and controlling them using g-codes and m-codes (which carry instructions for the tool’s movement) to create machine parts.

Depending on the project, there are many CNC machining techniques, each with advantages for machining HDPE.
CNC Milling HDPE
The most common CNC machining technique for HDPE is CNC milling. This technique involves removing material from the workpiece using rotating cutting tools. Depending on the project, several technologies are used, but the milling technique can machine HDPE parts with complex designs but at low-volume production.
CNC Turning HDPE
Another common CNC machining technique is CNC turning. This technique involves rotating the workpiece while a stationary cutting tool removes material. It can machine cylindrical HDPE parts like pipes, rollers, or bushings. However, unlike CNC milling, it is less flexible in handling complex geometries.
CNC Routing HDPE
The CNC routing machining technique is another popular technique for machining large, flat HDPE sheets. This technique can cut 2D shapes from these sheets, making it common in industries that require speedier sheet production, like HDPE parts.
CNC Drilling HDPE
We also can use CNC drilling alongside other CNC machining techniques. This CNC machining technique can create holes or channels in HDPE workpieces and is a common part machining technique where applications need exact hole placement.
