CNC Milling

Our CNC milling process produces custom prototypes and end-use production parts in as fast as 1 day. We use 3-axis milling and 5-axis indexed milling processes to manufacture parts from more than 30 engineering-grade plastics and metals.

CNC milling design guidelines will help you understand capabilities and limitations.

 

Why Use CNC Milling For Your Project?

Protolabs’ CNC machining service can deliver machined parts, in both plastic and metal, in less time than it takes to get a quote from other, more traditional machine shops. Upload a CAD file, choose the material and part quantity, and tell us when you need the parts.

CNC material data sheets can be found in our Material Comparison Guide

 

How Does CNC Milling Work?

We have multiple tool sets based on efficient cutters for a particular plastic or metal material. The machine then rapidly mills parts out of the block in a subtractive manufacturing process that uses 3- or 5-axis milling.

Machined plastic parts are left as-milled, which typically means they show visible tool marks. Some metal parts allow more finishing choices. When the run is complete and your required surface finish is applied, parts are boxed and shipped shortly thereafter.

Watch: CNC Machining process and capability

Proto Labs is the world's fastest source for custom prototypes and low-volume production parts. Our high-speed CNC machining service uses advanced CNC technologies to create parts ranging from highly complex prototypes to functional, end-use parts. A range a plastic and metal materials are available through two CNC processes: milling and turning. Get 1 to 200+ parts in as fast as one day with CNC machining at Proto Labs.



 

 

Watch: From Art to Part

Watch an initial concept for a product move from sketch to 3D CAD model to final part. Once a design is uploaded at Proto Labs, we provide an interactive quote with real-time pricing information and manufacturability feedback within hours. Product designers and engineers can choose from various injection moulding, CNC machining and 3D printing processes — all built to produce quick-turn parts in as fast as 1 day.


Design Guidelines

Our basic guidelines for CNC milling include important design considerations to help improve part manufacturability, enhance cosmetic appearance and reduce overall production time.
