Turning is a machining process used to create cylindrical parts by cutting away material from a workpiece. It's one of the most common operations performed on a CNC machine, and understanding the fundamentals of small part turning is essential for anyone who wants to get the most out of their machine. In this article, we'll cover the basics of small part turning, including what tooling is required and how to set up your machine for success.


The tooling section for small CNC part turning covers the basics of choosing and using the proper tooling for the job. It is essential to select the appropriate tooling for the material being machined, as well as the desired finish. The most common tooling used for small CNC turning is made from high-speed steel (HSS) or carbide.

HSS is the most common type of tooling used for small CNC turning. It is relatively inexpensive and can be used on a variety of materials. HSS tooling can be coated with titanium Nitride (TiN) to improve wear resistance and chip flow.

Carbide tooling is more expensive than HSS, but it offers a number of advantages. Carbide is much more complicated than HSS and can retain its cutting edge longer. In addition, carbide tools can be run at higher speeds than HSS without sacrificing quality or accuracy. 


Small CNC part turning is a process where a computer controls the movement of a cutting tool to remove material from a workpiece. This process can be used to create parts with complex shapes and features.

Small CNC part turning can be used to create high-precision parts. The process is often used to produce parts for medical or aerospace applications. Small CNC part turning can also be used to develop prototypes or one-off parts.

The small CNC turning process can be performed on various materials, including metals and plastics.

As a part of our series on small CNC machining, we're going to take a look at CNC turning. Turning is a process where the workpiece is rotated on a lathe while cutting tools are used to remove material. This can be done to create cylindrical or conical shapes.

CNC turning is an excellent option for small parts because it can be very precise and is relatively quick. Setup time is also shorter than with other methods like milling.

There are some things to keep in mind when considering CNC turning for your small parts. First , the diameter of the workpiece needs to be smaller than the length. Second, it's essential to have a good understanding of the cutting tools that will be used. And finally, the speed of the spindle and feed rate will need to be considered when choosing this method.


As part of the fundamentals of small CNC part-turning, understanding measurement is critical. This blog section will cover some of the basics of measuring small CNC-turned parts.

There are a few key things to keep in mind when measuring for small CNC- turned parts:

1. The first thing to consider is the size of the part. Small CNC-turned parts can be as small as a few millimeters in diameter, so it's essential to have a good understanding of what size the part needs to be. 

2. Another essential factor to consider is the tolerance, or how close to the desired size the part needs to be. With small CNC parts, even a tiny deviation from the desired size can cause problems, so it's essential to be aware of the tolerance requirements. 

3. It's also important to consider the surface finish when measuring small CNC parts. A rougher surface finish will require more material removal and higher tolerance, while a smoother surface finish can be achieved with less material removal and lower tolerance.

Keep these factors in mind when measuring for small CNC-turned parts, and you'll be sure to get the best results!


Sure, CNC part turning is a great way to automate your machining process and increase productivity. But what if you're not sure where to start? In this blog post, we'll cover the basics of small CNC part turning, including what it is, how it works, and some of the benefits it can offer your business.

What Is Small CNC Part Turning?

Small CNC part turning is a process of machining small parts using computer numerical control (CNC). A CNC machine is a computer-controlled machine that can be used to create exact parts. In a small CNC part turning, the machine is programmed to cut and shape the material into the desired shape. This process can be used to create parts for a variety of applications, such as medical devices, automotive components, and electronics.

How Does Small CNC Part Turning Work?

The first step in small CNC part turning is to create a computer-aided design (CAD) file of the desired part. This file will be used to generate the toolpaths, which are the instructions that tell the machine how to cut the material. Once the toolpaths are generated, they are loaded into the machine, and the cutting process begins. The machine will follow the toolpaths to cut and shape the material into the desired shape.

What is a Small Part Turning?

Small part turning is the process of machining small, cylindrical parts on a CNC machine. The process is similar to regular turning, but the parts are smaller in size and require more precise tooling and setup. Small part turning is often used for creating prototypes or small batches of parts that need tight tolerances.

What Tooling is Required for Small Part Turning?

The essential tooling for small part turning is the cutting tool. These need to be sharp and able to cut the material quickly and accurately. Smaller cutting tools are typically used for smaller parts, as they are less likely to cause vibration and can be more easily controlled. It's also essential to use tools that are designed specifically for small part turning, as regular turning tools can cause damage to the workpiece or create unacceptable tolerances.

In addition to cutting tools, another tooling such as chucks, lathe dogs, and live centers may be required depending on the specific application. These tools help to hold the workpiece securely while it's being machined and can also be used to support long or thin workpieces that might otherwise be difficult to turn safely.
