CNC Milling Services

CNC Machining

CNC milling is a subtractive manufacturing process that uses different tool types to remove or grind material from a piece of raw stock according to a programmed design, producing the desired part shapes and features. RevPart offers 5-axis CNC milling services, meaning that both the stock and the tools can move during the process, enabling the greatest versatility of design. We also specialize in plastic CNC milling for a broad range of material types.

Typical custom CNC milling applications include manufacturing holes, slots and other recessed structures, as well as dovetail joints, bevels and more. Precision CNC milling is also great for producing threaded features. Additionally, RevPart’s excellent CNC milling services can shape part contours. Our plastic CNC milling capabilities are most often drawn upon by the medical, aerospace, automotive, electronics, industrial, space and consumer industries.


Benefits of CNC Milling

CNC milling offers numerous benefits, which is why it is so broadly used across industries and applications. As a longtime CNC milling parts manufacturer, RevPart is committed to helping you realize these advantages and make a positive impact on your project. Primary CNC milling benefits include:

  • Cost efficiency: As one of the most common manufacturing methods in use today, CNC milling is a cost-effective solution to shape plastic parts and features. Material costs are typically low and setup time is minimal. Plus, it is a relatively high-speed technique that does not often require additional finishing processes, meaning less machine time and increased productivity.
  • Shape versatility: CNC milling is capable of producing a wide range of shapes, contours and part features. With 5-axis milling, our processes are especially versatile.
  • Smooth aesthetics: Create smooth corners, contours and an attractive appearance for consumer products and other applications. Although CNC milling can leave cut patterns on plastic, additional finishing is often not desired or required, keeping costs low and speed high.
  • Material versatility: CNC milling is suitable for any plastic that can be machined, making for a wide range of materials to compete with metal options. Generally, custom CNC milling for parts enables them to cost and weigh less, offering substantial advantages while maintaining similar strength.


CNC Milling Design Considerations and Options

In this section, we will look at some of the design considerations for our milling services.

  • Various recessed shapes: CNC milling is often used to create recessed structures, such as holes, slots, snap connectors and more. These recessions can be threaded or unthreaded. In fact, milling is often used to add features to already-machined parts, although the process is perfectly capable of producing entire parts on its own.
  • Rounded corners: Note that CNC milling produces visible cut patterns which — if a perfectly smooth finish is required — may require additional processing after milling.
  • Rounded corners: The nature of milling means that it is best suited for creating rounded corners. Right angles should be avoided for corners, edges and other part features.
  • Avoid deep pockets: Recessed pockets that are too deep can affect the strength of the part, making it susceptible to brittleness or failure.
  • Maintain sufficient wall thickness: Similarly, milling should not be used to create thin-walled features, since the material may break under the stress if it is machined too thin.

Frequently Asked Questions

Compared to traditional forms of milling, this process uses precision computer controls, rather than manual control. This means it is fully automated, capable of reproducing consistent results no matter how many times it is performed.


One of the primary benefits of the process is that it does a good job with a wide range of irregular geometries. On top of this, it also makes mass production more efficient after the initial setup is completed.


Yes — parts that have been produced using other methods including die casting or 3D printing can be put through CNC milling to add details and features.
