Guidelines for Designing CNC Turning

Our guidelines for CNC turning incorporate essential design considerations to optimize part manufacturing, improve cosmetic appearance, and reduce production time.

Max SizeDiameter3.95 in.100.33mm
Length9 in.228.6mm
Min SizeDiameter0.16 in.4.07mm
Length0.05 in.1.27mm
Wall Thickness0.020 in.0.51mm
+/- 0.005 in.+/- 0.13mm


Here are some essential tips to keep in mind when using CNC turning:

1. The diameter should be at least 0.030 inches (0.76mm) for any area, but small features can be added.

2. Sharp, pointed cones are permitted., but the angle should be greater than 30 degrees. Walls less than 0.020 inches (0.5mm) might not survive machining.

3. China Metal Parts can achieve a machining tolerance of plus or minus 0.005 inches (0.13mm).

Surface Finish Options for Turned Parts

Enze aims to improve the surface qualities of your products in a wide range of surface finishes, including appearance, surface hardness and roughness, and chemical and corrosion resistance. They also help hide any visible tool marks from areas cut with live tooling. Here are some of your top choices.

As Machined Surface Finishes

Machining finishing is a good option for those on a tighter budget, but it can leave tool marks on the surface of CNC-machined parts, making it unsuitable for high-value projects.


Anodized Finishing

Anodized finishing enhances the corrosion, wear, and hardness resistance while protecting the metal surface.


Bead Blasting 

Bead blasting removes cutter marks and scratches, giving a textured appearance.



The process produces a surface with significant specular reflection.


Powder Coat

Add a protective polymer coating to the part for wear and corrosion resistance. Various colors are available for aesthetic effect.


Black Oxide Coating

It improves the capacity to battle corrosion, offers wear resistance, and offers high lubricity. This surface finishing is the best option for steel, copper, and other alloys that form well-bonded bonds with oxygen molecules.



Electroplating protects workpieces and inner components from contaminants and corrosive impacts.

CNC Turning Tolerance and Size Limitation

CNC Turning Tolerance: For Metal, ± 0.005″ and Plastic ±0.05″

Size limitations for the metric parameter:

The max swing diameter is  0.3 to 3600 mm ( 0.011 to 141.732 inches).

The max cutting length is  0.5 to 1500 mm ( 0.019 to 59.055 inches).

Since CNC turning has numerical control machining size restrictions, it is necessary to select a suitable lathe machining according to the characteristics of the material, the lathe, and the machining method.

Overview of CNC Turning

What is CNC Turning?

Computer Numerical Control Turning(CNC turning) is a subtractive manufacturing process method that controls machine tools to cut metal, plastic, and other materials through program control. Our CNC lathes have live tooling that machine flat features and holes into the workpiece. Threading for the outside diameter (OD) and inside diameter (ID) is also an option. After turning, the parts can be left with visible tool marks or polished through bead blasting. After finishing, the parts go through an inspection process, get packed, and then are promptly delivered.

How Does CNC Turning Work?

CNC turning involves several steps:

Design: Create a CAD (computer-aided design)

Model Programming: Converte CAD model into a CNC program

Setup: The workpiece is securely clamped onto the machine’s chuck, and the cutting tool is inserted into the holder.

Operation: The cutting tool removes material from the workpiece as it rotates and moves along the x and z axes, shaping it to the desired form according to specifications.

Finishing: Once the turning operation is complete, the part may be polished or coated to enhance its appearance or functionality.

Advantages of CNC Turning

What are the advantages of CNC Turning? Why do we take the CNC turning process as one of the critical CNC machining processes?  

Assisted by CNC machines, manual operations in the turning process can be eliminated. It offers a fast and precise tool to machine the parts accurately through CNC turning, removing excess material to get the desired shape. 

The CNC turning process offers many benefits; let’s discuss the specific advantages:

High precision

CNC turning can produce parts with tight tolerances and good surface finishes, making them ideal for high-precision applications, thereby improving machining accuracy and stability.

High efficiency

CNC turning is a highly efficient process that can produce parts quickly and accurately, reducing lead times and increasing productivity.


CNC turning can adapt to different processing needs by changing molds, adjusting process parameters, etc., and has strong flexibility.


CNC turning is widely used to produce parts, from simple shafts to complex components with multiple features.

Good repeatability

CNC turning can achieve mass production by writing standardized processing programs, and the product quality is relatively stable and repeatable.

Cost savings

CNC turning can reduce labor input and the resulting errors and variables, reducing labor costs and scrap rates.

Improve safety

 CNC turning operations are usually automated, which can effectively protect the health and safety of workers.


Frequently Asked Questions

Enze follows strict quality control measures to ensure that all parts produced meet your requirements. We use advanced measuring and inspection equipment to verify the accuracy and consistency of each component. Our engineers and technicians are willing to provide our clients with solutions that meet various specifications.

The difference between CNC turning and milling is that CNC milling uses a rotating tool, while CNC turning uses a rotating part for cutting.

In our daily lives, the most common turning objects are auto parts, elevator components, new energy rods, and other round items.
