What is CNC Milling

CNC milling is to cut solid plastic or metal material into final precision parts using different axis milling processes. Unlike CNC lathes, CNC mills remove material from the workpiece by rotating and moving a cutting tool, such as a milling cutter, and position the workpiece properly, to create a finished or semi-finished shape.

The multi-axis milling machines realize a versatile, accurate, and repeatable CNC milling process for the production of different features and complex geometries. Take channels, holes, curves, and corners for some examples. Milling can be also used as a perfect way of making tooling for die casting and injection molding.

Our advanced facilities conclude imported 3-axis, 4-axis, and 5-axis CNC mills that are equipped with different tool sets to maximize production efficiency and speed. Send us your inquiry or 3D files online to get an online quote for free now.[Get Quote]

Advantages of CNC Milling Processes

  • Making angled shapes

    CNC milling is an ideal choice for manufacturing angled shapes, planes, grooves and channels, holes, curves, chamfers, and many other features.

  • Rapid tooling

    Milling is not only used to manufacture finished parts, but also used to build molds for plastic injection molding and pressure die casting.

  • High accuracy

    CNC milling machines can remove a large number of materials quickly and accurately, and produce good surface finishes at the same time.

  • Various material options

    CNC milling can machine different parts with a variety of materials. This process can be carried out on any rigid material.

  • Versatile

    Milling is the most versatile of all available CNC machining processes.

  • Cost-effective

    Because no other specialty tools need to be manufactured and no requirements for minimum order quantity, the process is highly cost-effective and almost no waste compared with additive manufacturing.

  • Time-saving

    Minimal setup time makes it possible that CAD files can be converted to finished products in a few hours.

  • Cost-Effectiveness

    CNC milling makes up for the initial cost with high productivity and fewer part errors to efficiently manufacture your part or prototype and achieve a true-to-life part of your design.

CNC Milling FAQs

  • Q

    What is CNC machining?


    CNC milling is just one of the CNC machining processes available. Milling is a particular form of precision CNC machining. Milling uses a cutter that removes material by moving into the workpiece at an angle. The movement of the cutter is controlled by computer instructions, allowing for extreme precision and repeatability.

  • Q

    Why use CNC milling?


    Besides CNC turning, CNC milling is one of the most popular custom CNC machining processes. CNC milling services are used for the majority of machined parts because it can handle a wide variety of irregular geometries. It is also an efficient means of mass production once the setup is complete.

  • Q

    What kinds of CNC milling machines does NOBLE have?


    NOBLE works with vertical, horizontal, and multi-axis milling machines. The vertical milling machine is highly accurate equipment that carries out 3-axis milling, suitable for vertical surfaces and angular shapes.

    Our horizontal milling machines perform 4-axis milling and are suitable for heavy milling operations. Our multi-axis milling machines can move along different axes and cut at various angles. They include 2-, 3-, 4-, and 5-axis CNC milling machines.

  • Q

    Can I combine CNC milling with 3D Printing?


    Yes, you can combine both manufacturing processes to reinforce your custom parts. Printed parts can be milled to achieve dimensions with tight tolerances or to meet surface quality requirements. Intelligently combining these two methods can ensure faster manufacturing, less waste, and lower costs. It even achieves higher accuracy and precision, repeatability, and sustainable production.

  • Q

    How does CNC milling work?


    CNC milling starts with designing a digital part with CAD software. Then the file will be converted into CNC readable program code, which can be recognized by a CNC mill and dictates to the mill how to rapidly fabricate parts from raw material blocks.

    Different from CNC lathes or turning centers where a stationary cutting tool removes material by making contact with the spinning workpiece, CNC mills cut away block or bar stock by a rapidly rotating cutting tool moving against the workpiece. The tool path is controlled by computer instructions, enabling improved reliability and repeatability regardless of potential human error.

  • Q

    What are the types of CNC milling operations?


    Different milling types can achieve different functions and can be suitable for different applications. Usually, CNC milling services can be divided into the main 8 types of operations:

    Gear Milling
    Thread Milling
    Plain Milling
    Form Milling
    Face Milling
    Angular Milling
    Profile Milling
    Straddle Milling

  • Q

    What kinds of CNC milling machines do you employ?


    We quote German and Japanese advanced equipment including imported three-axis, four-axis, and five-axis CNC milling machines equipped with different tool sets to maximize production efficiency and speed.

  • Q

    What should I note for CNC milling design?


    CNC milling is used to produce many typical geometry parts with tight tolerances and high accuracy. In the precision CNC milling design process, we recommend typical CNC milling parts including complex planes, curved surfaces, shell parts, connecting rods, propellers, and component housings. But consumers should also notice that some factors like thin walls, deep cavities, and inner wall cutouts may be not suitable for the CNC milling process.

    We provide professional design considerations as follows:

    Avoid Sharp Internal Corners.
    Avoid Narrow, Deep Slots.
    Avoid flimsy shapes.
    Corner radio of 10% or more of wall height is ideal.
    Avoid flimsy shapes.
    Practical shape as straight edges.
    Weak shapes are difficult to mill, such as long thin shapes and thin walls.
    Visible cutting surface pattern for cutter rotation and movement.

  • Q

    What’s the difference between CNC milling and CNC lathe?


    The major difference between CNC milling and CNC lathe is in their machining process. CNC milling involves rotating the cutting tools against a stationary bar stock or workpiece. In contrast, a CNC latter works by rotating the bar stock or workpiece against a stationary tool. CNC milling is more suitable for machining irregular and flat surfaces, while CNC lathes work best for cylindrical or conical parts.
