What is CNC Turning?
CNC turning is a subtractive manufacturing process, which means it starts with a larger block of material and removes what is needed in order to form the final part. Turning uses computer numerical control (CNC) to spin a part and control the movement of cutting tools to remove material to create a desired shape.
CNC turning is a highly versatile process that can be used to create a wide range of parts, from simple shafts to complex geometric shapes. Depending on the type of CNC machine used, turning machines can also add holes, change tooling, add milled-style features, etc. for more complicated parts.

What Types of Parts Can Komacut Make With CNC Turning?
In general, the parts more commonly made with CNC turning are cylindrical, with or without threading, which require a level of precision that simpler processes cannot provide. This can include such common mechanical parts types as:
- Bushings
- Pins
- CNC turned screws and bolts
- Shafts
- Axles
- Nuts
What Applications Is CNC Turning Used For?
CNC turning is used to manufacture a wide variety of parts in a wide range of industries, including:
- Automotive
- Aerospace
- Medical
- Electronics
- Industrial machinery
- Consumer goods
Basically, any possible application that requires precise metal and plastic pins, shafts, axles, pins and other parts will utilize CNC turning.
CNC Turning Process
The CNC turning process typically involves the following steps:
- Setup: The workpiece is loaded into the CNC lathe and secured in a chuck.
- Programming: The CNC lathe is programmed with the desired part geometry.
- Machining: The CNC lathe rotates the workpiece and moves the cutting tools to remove material according to the programmed geometry.
- Inspection: The finished part is inspected to ensure that it meets the required specifications.
Commonly Asked Questions for CNC Turning
CNC turning involves rotating the part while the cutting tool remains stationary, whereas in milling, the cutting tool rotates and the part is generally fixtured in place.
CNC milling is more flexible in the types of geometries it can make, but due to the high speed cutting and simple processing, CNC turning is very cost competitive for simple to relatively complex cylindrical parts.
CNC turning is known for its high precision and accuracy, capable of meeting tight tolerances for intricate designs. Refer to the tables below.
Yes, CNC turning is capable of handling complex geometries. This technology is highly versatile and can be used to create parts with intricate designs and detailed features.
