What Is CNC Milling

It is a typical and common machining process. It utilizes computerized controls to manufacture custom-designer machining parts, By optimizing the movement and operation of rotary cutting tools, the CNC machine will remove the excess material of the workpiece to achieve the required shape and dimensions. These milling parts have a good quality and precision surface finish. The milling process is welcomed in many industries because of its accuracy, consistency, and ability for mass production and stability. The serving industries include aerospace, shipping, automobiles, oil drilling, pump, electronics manufacturing, and precision engineering sectors. A CAD drawing is the beginning of the milling process, the drawing is used to control the output of the CNC machining process.

Advantages of CNC Milling

It is more advanced and provides a wide range of benefits compared with traditional manual milling methods, including:

  • 1

    High production:

    CNC machines can produce thousands of parts within a shorter time, and also it makes possibilities to allow for larger scale production with higher repeatability.

  • 2

    Less labor

    CNC mill is the most common type of CNC machining, by Using a CAD program and optimizing the machining strategies, there’s little requirement for skilled labor.

  • 3

    Superior precision

    Since the machine is controlled by CAD/CAM software and works automatically. It greatly ensures precision and stability by eliminating the risk of human labor.

  • 4

    Material universality

    The CNC milling process can be used to machine a wide range of materials, including hard materials, such as HSS.

  • 5

    Dimension uniformity

    CNC milling allows the same parts to be machined over and over again with uniform dimensions.

  • 6


    Computer-controlled machining makes. it very affordable over traditional manufacturing methods
