CNC Milling Services – HJY

CNC Milling Service

What is CNC Milling?

CNC milling, also known as computer numerical control milling, is a machining process that uses computer-controlled and rotating multipoint cutting tools to remove material from a workpiece.

CNC Milling Process

In CNC milling, the process begins with a digital design or computer-aided design (CAD) file that specifies the dimensions and geometry of the desired part. This CAD file is then converted into a computer-aided manufacturing (CAM) program that CNC mills can understand.

A CNC milling machine consists of a table or table that securely holds the raw material, usually metal or plastic, and a cutting tool that rotates at high speed. The machine is controlled by a computer that guides the movement of the tool along multiple axes (usually three or more), allowing it to precisely cut and shape the workpiece.

During milling, the cutting tool moves in various directions to remove material from the workpiece, following instructions provided by the CAM program. The tool can perform different operations such as drilling, facing, contouring, pocketing or slotting to obtain the desired shape and features.

Advantages and Disadvantages of CNC Milling


Precision and Accuracy

CNC milling machines can achieve high levels of precision and accuracy, often within tight tolerances. This ensures consistent and reliable production of complex parts with intricate details.

Automation and efficiency

Once a CNC mill is set up and a program loaded, it can run continuously with minimal human intervention. This automation increases productivity as multiple operations can be performed in one setup, reducing overall production time.


CNC mills can machine a wide variety of materials, including metals, plastics, composites, and even some types of wood. They can be produced in a variety of shapes, sizes and features, making them suitable for a variety of applications.


Required Skills

Operating and programming a CNC milling machine requires specialized knowledge and skills. Operators must be trained in programming, machine setup, tool selection and troubleshooting. This skill requirement can be a barrier for some individuals or companies.

Limited flexibility

CNC milling machines are best suited for repetitive and high-volume production. If frequent design changes or one-off parts are required, setup and programming time may outweigh the benefits of CNC milling.

Maintenance and downtime

CNC mills require regular maintenance to ensure optimal performance. Mechanical failures, software failures or tool wear can cause downtime and production delays.
