CNC Turning Servcies

CNC turning services helps fabricate contoured cylindrical parts while providing repeatability, exceptional accuracy, high precision, and cost-effectiveness. With the help of turning, a wide range of shapes can be given to the workpiece, such as cylinders, cones, disks, polygonal, hexagonal, or a combination of these shapes with axial symmetry. It is helpful in both small batches and mass production.

The Types of CNC Turning Services

CNC turning is a lathe tooling operation that removes the material from the external surface of the workpiece. The type of CNC turning services below:


Cylindrical Turning

It is a process that reduces the diameter of the workpiece uniformly in order to prevent any variation in the cutting diameter. 


Taper Turning

Taper turning is the one in which a cylindrical shape is created out of a workpiece with a decreasing diameter.



Grooving is a type of CNC turning process in which a narrow cavity is formed by pressing a shaped tool into the workpiece.



Parting is the process in which gouging is done for removing the whole piece from the original workpiece.


Spherical Generation

A form is created around a fixed axis with the help of a program for lowering the diameter to zero to obtain a perfect spherical shape.



The knurling process is one in which a workpiece is cut into a serrated pattern. It is used for those materials needing extra grip.



Threading is a type of CNC turning. It helps in making grooves that can make the workpiece to be easily screwed into other objects.



A single-point tool is fed linearly, parallel to the axis of rotation, on the inside diameter of an existing hole in the part.

How does CNC Turning Work?

CNC Turning Services

CNC turning is a manufacturing process that involves rotating a workpiece while a cutting tool removes material from the workpiece to produce the desired shape or dimension. The process is automated and controlled by computer numerical control (CNC) software.

Here are the basic steps of CNC turning:

Workpiece setup:

The workpiece is mounted onto the spindle of the lathe. The lathe may have a chuck or collet to hold the workpiece securely in place.

Tool setup:

A cutting tool is selected based on the desired shape and material of the workpiece. The tool is mounted onto the tool turret of the lathe.


The CNC software is used to program the lathe with the desired dimensions and shape of the final product. This includes the speed and feed rate of the cutting tool.


The lathe begins to rotate the workpiece at a specified speed, and the cutting tool moves across the surface of the workpiece, removing material to produce the desired shape.


Once the rough shape is produced, the cutting tool is replaced with a finishing tool that produces a smooth surface finish on the workpiece.


The finished workpiece is inspected to ensure that it meets the desired specifications.

CNC Machining FAQs

A: CNC machining is a wide-ranging manufacturing category involving multiple computer-managed processes. The objective is to remove enough raw material from a piece to achieve a state of near completion.

A: Aria is a professional CNC machining manufacturer in China, The reliability and precision of high-tech tools powered by sophisticated software programs give CNC machining the ability to quickly generate prototypes and complicated end-use parts having exceptionally tight tolerances. with low cnc machining costs from Chinese.

A: CNC machining is a subtractive manufacturing process. When the material is added instead of removed, it’s called an additive manufacturing process. Examples of subtractive CNC machining include specialized applications such as CNC milling services, turning, surface grinding, and EDM. An example of additive CNC machining is 3D printing.

A: The spinning motion from the CNC machine’s cutter will leave visible tool marks. Although they stand ready for immediate service, they can be further refined with anodizing, painting, polishing, and plating.
