A Quick Comparison: Different Types of CNC Machine Tools


In this blog post, we will provide a quick comparison of the different types of CNC machine tools. In the realm of manufacturing, CNC (Computer Numerical Control) machine tools have revolutionized the way parts and components are fabricated. These advanced machines are programmed to execute various machining operations, offering versatility and accuracy. Whether you’re a manufacturing professional, an aspiring machinist, or simply curious about the world of CNC machines, this guide will help you navigate through the diverse landscape of CNC machine tools.

CNC Milling Tools (CNC Cutting Tools)

A CNC milling tool is a cutting tool used to remove material from a workpiece by rotating and moving along multiple axes, guided by the CNC control system. CNC milling tools are crucial components in CNC machining processes. Enabling precise and efficient material removal to create complex shapes, profiles, and surface finishes. Here are some key types of CNC milling tools to consider:

End Mills

  • A cutting tool used in milling operations to remove material and create precise contours and features on the surface of a workpiece.

Slab Mills

  • A type of milling cutter with a wide, flat cutting surface. That removes large amounts of material in a single pass.

Face Mills

  • A milling cutter is designed for facing operations, creating flat surfaces perpendicular to the spindle axis of the milling machine.

Fly Cutters

  • A single-point cutting tool mounted on a rotating spindle. Typically used in milling machines to produce a smooth surface finish by removing material in a single pass.

Hollow Mills

  • A specialized cutting tool used in turning or milling operations to create hollow features in a workpiece.

Other CNC Cutting Tools

  • Reamers
  • Side-and-face cutters
  • Thread mills
  • Involute Gear Cutters

CNC Turning Tools

A CNC turning tool is used to remove material from a rotating workpiece to create cylindrical shapes. CNC turning tools are available in various types, each designed for specific turning operations. These tools are essential in CNC turning operations. They allow for precise and efficient material removal to achieve desired dimensions, surface finishes, and geometries. Consider these types of CNC turning tools:

Boring Tools

  • A cutting tool used to enlarge or refine existing holes in a workpiece with high precision and accuracy.

Chamfering Tools

  • A cutting tool used to create bevelled or angled edges, on the corners or edges of a workpiece. Provides a finished and deburred appearance.

Knurling Tool

  • A cutting tool used to create a textured pattern of diamond-shaped or straight-line ridges on the surface of a workpiece, improving grip and aesthetics.

Parting Tool

  • A cutting tool that is used to cut or separate a workpiece into two distinct parts by creating a groove or cut along a predetermined line.

Drilling Tools

A CNC drilling tool is a cutting tool used to create holes in a workpiece by removing material through rotational cutting motions. These tools are vital for CNC drilling operations, enabling precise and accurate hole creation in a range of materials, such as metal, wood, plastic, and composites. Take into account the following varieties of CNC drilling tools:

Center Drills

  • A specialized cutting tool that is used to create a precise starting point or center hole for subsequent drilling or turning operations.

Ejector Drills

  • A specialized cutting tool used in drilling operations that features an internal spring mechanism to automatically eject the drilled material from the hole, facilitating efficient chip evacuation.

Twist Drills

  • A common cutting tool used in drilling operations that features spiral flutes to efficiently remove material and create cylindrical holes in a workpiece.

Grinding Tools

A CNC grinding tool is a cutting tool used to remove material through abrasive cutting and grinding processes to achieve precise shapes, dimensions, and surface finishes on a workpiece. CNC grinding tools enable the precise shaping and finishing of surfaces, edges, and profiles, ensuring high levels of accuracy and surface quality.


The world of CNC machine tools offers a diverse range of options, each tailored to specific machining requirements and applications. Whether it’s CNC milling machines for versatile material removal, CNC turning machines for cylindrical component fabrication, or CNC machining centers for comprehensive machining operations, there is a CNC machine tool to meet every manufacturing need. By understanding the unique features and benefits of different types of CNC machines, manufacturers can make informed decisions to enhance productivity, precision, and efficiency in their operations.
