PlasticHubs delivers high-precision CNC milling services engineered for accuracy, consistency, and fast production. Our milling capabilities support rapid prototyping and low-to-high volume production with tight tolerances and high-quality surface finishes.
CNC milling is a subtractive manufacturing method where rotating cutting tools remove material from solid plastic blocks. The process supports 2D and 3D geometry creation, allowing detailed features such as pockets, curved surfaces, cavities, mounting structures, and precision contours. It is ideal for functional prototypes, housings, fixtures, and structural components.
Building on this foundation, modern CNC milling further extends its versatility through multi-axis configurations. By synchronizing movement across 3-, 4-, or 5- axes, the machine can reach complex angles without manual repositioning, enabling the creation of undercuts, deep cavities, compound curves, and highly contoured geometries.
This capability significantly improves accuracy on intricate parts, shortens production cycles, and ensures consistent quality across repeated runs. For plastic components used in assemblies, optical structures, or high-performance mechanisms, multi-axis milling provides the freedom to achieve tighter tolerances and more advanced design intent in a single, continuous setup.
CNC milling operates by translating digital design data into precise, automated tool movements. Once a 3D model is programmed into the machine, the system calculates toolpaths, selects cutting strategies, and controls spindle speed, feed rate, and tool engagement. The cutting tool then removes material layer by layer, shaping the workpiece with controlled accuracy. Throughout the process, the machine monitors position and motion in real time, ensuring dimensional stability and repeatability across every part.
CNC milling controls tool movement with high accuracy, allowing it to create pockets, contours, and 3D surfaces with tight tolerances. This makes it reliable for plastic parts that must fit or function with exact precision.
The rotating cutting tool produces smooth finishes and sharp details directly from the machine. This reduces polishing work and supports applications such as clear components, display elements, or visible housings.
Milling tools can reach into deep cavities, narrow slots, ribs, and internal details that other processes struggle with. This capability is ideal for functional prototypes and parts with complex internal structures.
With 3-, 4-, or 5-axis options, CNC milling completes multiple faces or angles in fewer operations. This improves turnaround speed and ensures consistency across batches, especially for low-volume precision plastic parts.

Here are the plastic materials most commonly used in our CNC milling service, with the option to support metals when project requirements call for it. Each material below offers distinct machining characteristics that make it suitable for different functional needs.
Known for its clarity and crisp edge definition, acrylic machines cleanly and delivers excellent optical-grade surfaces when cut at proper speeds.
With its low friction, high stiffness, and stable cutting behavior, POM supports tight tolerances and produces smooth, dimensionally reliable parts.
This high-performance polymer maintains rigidity under heat and stress, and machines into precise, durable components for demanding mechanical applications.
Polycarbonate handles machining well with the right parameters, offering toughness, impact resistance, and clean finishes suitable for structural or transparent parts.
Nylon mills smoothly into lightweight, strong components; its slight flexibility helps absorb impact, though attention to moisture control enhances dimensional accuracy.
ABS provides balanced strength and machinability, allowing sharp details, stable cutting, and reliable performance for enclosures, fixtures, and general prototypes.
Here is a list of standard CNC milling surface finishes available at PlasticHubs. For custom surface finishes, please don’t hesitate to contact us.
Produces a clean, uniform appearance directly from the cutter, with visible but fine tool marks and dependable dimensional accuracy.
Creates a smooth, glossy surface, ideal for clear plastics or parts that require improved transparency and refined visual quality.
Applies a matte, even texture that reduces glare and hides minor machining marks, suitable for both aesthetic and functional surfaces.
Offers customizable colors and finishes while adding a protective coating, often used for housings, prototypes, and display parts.
Used for metal components, providing enhanced corrosion resistance, improved hardness, and a uniform decorative appearance.
Adds a thin metallic layer to metal parts for increased wear resistance and visual appeal, often used in premium or high-contact components.
Delivers precise marking of logos, text, or identification codes without affecting part integrity, suitable for both plastics and metals.
CNC milling is widely used to create precise, functional components for prototyping, tooling, and low-volume production needs.
