Is CNC Machining And Milling The Same Thing?
In the world of precision parts machining and customization, terms like CNC machining and milling are commonly heard. However, many clients often wonder if they are the same thing. In this blog post, we’ll explore the differences and similarities between CNC machining and milling, and also introduce you to a reliable partner in this field – GreatLight CNC Machining Factory.
Understanding CNC Machining
CNC, which stands for Computer Numerical Control, is a manufacturing process that uses pre – programmed computer software to control the movement of factory tools and machinery. CNC machining is a highly versatile process that can be used to create a wide variety of parts with high precision. It can involve different types of operations such as turning, drilling, and milling.

GreatLight CNC Machining Factory, established in 2011 in Chang’an District, Dongguan City, China, is a professional five – axis CNC machining manufacturer. With advanced five – axis CNC machining equipment and production technology, it can handle most materials and provide one – stop post – processing and finishing services. The factory covers an area of approximately 7600 square meters, has 150 employees, and is equipped with 127 pieces of precision peripheral equipment, including large high – precision five – axis, four – axis, and three – axis CNC machining centers.

What is Milling?
Milling is a specific type of machining operation within the CNC machining umbrella. It involves using rotary cutters to remove material from a workpiece. The cutter moves in multiple directions to create the desired shape. Milling can produce complex shapes, slots, and holes in a workpiece.
There are different types of milling operations, such as face milling, peripheral milling, and end milling. Face milling is used to create flat surfaces, while peripheral milling is used to cut along the edges of a workpiece. End milling is used for creating slots, pockets, and profiles.
Differences between CNC Machining and Milling
Scope: CNC machining is a broader term that encompasses various machining processes, including milling. Milling is just one of the operations that can be performed in a CNC machining setup.
Tool Variety: In CNC machining, different tools can be used depending on the operation. For example, turning operations use lathe tools, while milling operations use milling cutters.
Complexity of Operations: CNC machining can handle more complex and diverse operations compared to milling. For instance, CNC machining can perform turning and drilling operations simultaneously, which is not possible in a simple milling process.
Similarities between CNC Machining and Milling
Precision: Both CNC machining and milling are known for their high precision. They can achieve tight tolerances, with GreatLight CNC Machining Factory capable of processing to ±0.001mm / 0.001 In and above.
Automation: Both processes are automated, which means they use computer – controlled systems to operate the machinery. This reduces the chances of human error and increases the efficiency of production.
