Machine tools are, hands down, an essential component of CNC machining.

They make the manufacturing process possible, helping us craft perfect custom-machined parts and products. Simple structure or super-complex, 3D shape or 5D, 2mm piece or 200mm- there is nothing apt CNC machining tools can’t create.

Simply put, if the CNC machine is the brain, machine tools are the limbs- converting instructions into actual action.

While CNC machine tools are fairly new, two-three decades-old- machine tools have existed for a long time. They were there even before CNC or anything computer machinery came into existence.

As everything is machine-related, CNC machine tools have gradually evolved with time. The manually handled tools have now transformed into computerized ones that decrease our workload by a hundredfold.

We can now repeat sequences and create millions of similar pieces with an accuracy of a marksman.

To achieve machined parts of different shapes, a CNC machine utilizes several different types of CNC tools. Additionally, several other types work exceptionally well with certain materials like wood, metal, and more.

Some work on different speeds and feed to get perfect custom machined parts.

All in all, there are several types of CNC machine tools. Let’s look at the types and functionalities. 

CNC Machine Tool Types

Milling Machines

Milling machines are used for cutting, drilling, and boring operations. There are two types of milling machines:

  • Vertical Machining Centers – These machines have a vertically oriented spindle that moves the workpiece vertically. They are ideal for flat parts that require drilling, milling, or tapping.
  • Horizontal Machining Centers – These machines have a horizontally oriented spindle that moves the workpiece horizontally. They are ideal for complex parts that require 4-axis or 5-axis CNC machining.

Turning Machines

Turning machines create round parts by removing material from the workpiece. There are two types of turning machines:

  • Horizontal Lathes – These machines have a spindle that is parallel to the ground and hold the workpiece in a horizontal position. They are ideal for creating long, slender parts.
  • Vertical Lathes – These machines have a perpendicular spindle to the ground and hold the workpiece vertically. They are ideal for creating large, heavy parts.

Grinding Machines

Grinding machines remove material from a workpiece by grinding it with an abrasive wheel. There are two types of grinding machines:

  • Surface Grinders – These machines grind flat surfaces on a workpiece. They are ideal for creating smooth finishes on parts.
  • Cylindrical Grinders – These machines are used for grinding cylindrical surfaces on a workpiece. They are ideal for creating precise cylindrical parts.


Other types of CNC machine tools are commonly used in manufacturing:

  • Electrical Discharge Machines (EDMs) – These machines use electrical discharge to remove material from a workpiece. They are ideal for creating complex shapes or cutting hard materials.
  • Laser Cutting Machines – These machines use a laser beam to cut through the material. They are ideal for cutting through thin sheets of material, such as metal or plastic.

CNC Machine Tool Functionalities

Precision Machining

Precision machining is one of the primary functions of CNC machine tools. CNC machines can achieve very high levels of accuracy and repeatability in the parts they produce. It is achieved through high-precision sensors and actuators, which allow the machine to precisely control the cutting tool’s movement.

High-Speed Machining

High-speed machining is another crucial function of CNC machine tools. Using high-speed spindles and cutting tools, CNC machines can achieve faster cutting speeds and higher material removal rates. This allows manufacturers to produce parts more quickly and efficiently, reducing production times and costs.

Multi-Axis Machining

CNC machines can perform multi-axis machining operations, which involve moving the cutting tool along multiple axes simultaneously. This allows manufacturers to create complex, three-dimensional shapes and features that would be difficult or impossible to create using traditional machining methods.

Tool Changing

CNC machines are capable of changing cutting tools automatically without the need for operator intervention. This allows manufacturers to use multiple cutting tools in a single machining operation, reducing the need for manual tool changes and increasing efficiency.

Program Storage and Retrieval

CNC machines are capable of storing and retrieving machining programs electronically. This allows manufacturers to easily recall and reuse machining programs for future production runs, reducing setup times and increasing productivity. It also allows for easy modifications to existing programs, making it easy to update part designs or make other changes.
