Turn your digital designs into precise, production-ready parts with CNC machining. From rapid prototypes and functional components to low- and medium-volume production, 3DSPRO provides CNC machining services with a wide selection of engineering metals and plastics, multiple machining processes, and professional surface finishing options to meet your project requirements.
CNC machining is a computer-controlled subtractive manufacturing process that removes material from a solid workpiece using precision cutting tools. Based on a digital CAD model, CNC machines can mill, turn, drill, tap, and cut materials into accurate and repeatable parts. Unlike additive manufacturing, CNC machining starts with a solid block, rod, or sheet and removes material until the desired geometry is achieved, which makes it particularly suitable for applications requiring tight tolerances, high strength, excellent dimensional stability, and smooth surface finishes.
CNC machining can produce highly accurate components with tight dimensional tolerances.
CNC machined parts retain the mechanical properties of the selected engineering material.
CNC machining naturally produces a clean and consistent machined surface.
CNC machining is well suited to various engineering metals.
Multi-axis CNC machining can access multiple surfaces of a workpiece and produce complex features.
CNC machining can produce prototypes from the same or comparable production-grade materials.
Once customers upload their CAD files and place an order, we review the design, select the appropriate machining process and material, manufacture the parts, inspect them, and prepare them for shipment.
Our engineers review the CAD model and technical requirements to identify potential manufacturability issues.
The approved design is prepared using CAM software to generate machining toolpaths and machine instructions.
The CNC machine follows the programmed toolpaths to remove material from the workpiece.
After machining, parts can receive additional surface treatments
Finished parts are inspected to verify dimensions, appearance, and other specified requirements.
CNC milling uses computer-controlled cutting tools to remove material from a solid workpiece and create precise shapes and features. It can produce complex 3D geometries, holes, pockets, slots, and contoured surfaces with high accuracy. CNC milling is suitable for a wide range of prototype and production parts.
CNC turning rotates a workpiece while a cutting tool removes material to create cylindrical and rotational features. It is commonly used for shafts, pins, bushings, sleeves, and other round components. CNC turning can produce accurate diameters, threads, grooves, and other features with consistent quality.
CNC routing uses a computer-controlled router to cut, engrave, and shape materials along programmed paths. It is particularly suitable for large or flat workpieces and can efficiently produce panels, plates, templates, and other components with two-dimensional or relatively simple three-dimensional geometries.
Precision machining focuses on producing components with tight dimensional tolerances and highly accurate features. Advanced CNC equipment, appropriate tooling, and controlled machining processes can achieve consistent results for parts that require precise fits, critical dimensions, and fine surface finishes.
Large part CNC machining is used to manufacture oversized components that require large working envelopes and stable machining processes. It can produce large frames, structural components, housings, molds, and other parts while maintaining dimensional consistency across the workpiece.
Metal materials are a strong choice for CNC machining when parts need high mechanical strength, dimensional stability, wear resistance, or reliable performance under heat and stress. CNC machined metal parts are widely used in aerospace, automotive, robotics, industrial equipment, medical devices, electronics, and heavy-duty assemblies.
Metal is widely used in CNC machining because of its high strength, durability, heat resistance, and suitability for demanding applications. Common options include Stainless Steel, Mild Steel, Brass, Copper, and Titanium. CNC machined metals are commonly used for aerospace components, automotive parts, industrial machinery, medical devices, electronic components, brackets, and functional prototypes.

Plastic is widely used in CNC machining because of its lightweight, good machinability, corrosion resistance, and versatility for functional and end-use parts. Materials such as ABS, POM (Delrin), Nylon, Polycarbonate (PC), PTFE, and UHMWPE can be CNC machined into functional parts with consistent dimensions and good surface quality.
Engineering plastics offer a practical solution when low weight, electrical insulation, chemical resistance, or smooth mechanical movement is more important than maximum structural strength. They are often selected for housings, covers, gears, rollers, bushings, insulating components, laboratory equipment, and lightweight mechanical assemblies.
CNC machining is a subtractive process that removes material from a solid workpiece, while 3D printing builds parts layer by layer. CNC machining generally provides superior dimensional accuracy, surface finish, and mechanical properties from production-grade materials.
3D printing offers greater geometric freedom and is often more efficient for highly complex shapes, internal structures, and certain low-volume applications.
CNC machining does not require expensive production tooling and can therefore be more practical for prototypes, customized parts, and low- to medium-volume production.
Injection molding becomes more economical for large quantities of identical plastic parts once tooling costs are distributed across a high production volume.
CNC machining removes material from a solid workpiece to create precise three-dimensional components. CNC machining is generally better suited to solid parts, tight tolerances, and intricate machined features.
Sheet metal fabrication forms relatively thin metal sheets through processes such as cutting, bending, and forming.
CNC machining produces parts directly from solid stock and can achieve excellent dimensional control and surface quality without casting molds.
Metal casting is more suitable for larger or highly complex metal components and high-volume production, particularly when near-net-shape manufacturing can reduce machining requirements.
