What Is CNC Turning?
CNC turning is a highly precise and efficient subtractive machining process that works on the principle of the lathe machine. It involves placing
the cutting tool against a turning workpiece to remove materials and give the desired shape.

What is the Difference Between CNC Turning and Milling?
While CNC turning rotates the part for cutting, CNC milling rotates the tool to cut the part.
Going further, CNC turning will typically be used for cylindrical parts, as you rely on the part itself to rotate and create the friction to
remove material when the cutting tool is placed against it.
On the other hand, CNC milling can create more complex parts as it is the cutting tool (rather than the material) that is spinning.
Our advanced CNC turning center routinely works with a wide variety of materials, ranging from copper, brass, stainless steel, carbon steel, aluminum, and titanium. We can always choose a suitable precision turning process to reach your requirements. Our custom CNC machining services ensure that our customers receive the highest quality CNC turned parts.

Materials for CNC Turning
We stock a range of metal materials that are suitable for various part applications and industries.
Choose from aluminum, brass, low carbon steel, stainless steel, steel alloy, and titanium for turned parts.
The main parameters for CNC turning are:
Spindle speed. The unit is rotations per minute (rpm) and it shows the rotational speed of the sp indle (N), thus also the workpiece. The spindle speed is in direct correlation with the cutting speed which also takes the diameter into account. Therefore, the spindle speed should vary to maintain a constant cutting speed if the diameter changes considerably.
|
Workpiece diameter. As said, this plays an important role in arriving at the right cutting speed.The symbol is D and the unit is mm.
|
Cutting speed. The equation for calculating the cutting speed is V=πDN/1000. It shows the relative speed of the workpiece to the cutting tool.
|
Feed rate. The unit is mm/rev and the symbol is s. Cutting feed shows the distance the cuttingtool moves per one turn of the workpiece. The distance is measured axially.
|
Axial cut depth. Pretty self-explanatory as it shows the depth of a cut in the axial direction. It is the primary parameter for facing operations. A higher feed rate puts more pressure on the cutting tool, shortening its lifetime.
|
Radial cut depth. The opposite of axial cut, this parameter shows the depth of cutting perpendicular to the axis. Again, lower feed rates help to lengthen the lifetime of tools and secure a better finish.

Frequently Asked Questions
1. What is your maximum diameter capacity for turned parts?
We can turn parts with diameters ranging from 0.5mm to 65mm for stock bars.
Our turning capabilities can reach up to 3000 mm for billets.
2. What’s the difference between CNC milling and CNC lathe?
The major difference between CNC milling and CNC lathe is in their machining process.
CNC milling involves rotating the cutting tools against a stationary bar stock or workpiece.
In contrast, a CNC lather works by rotating the bar stock or workpiece against a stationary tool.
CNC milling is more suitable for machining irregular and flat surfaces, while CNC lathes work best for
cylindrical or conical parts.
3. What parts can CNC turning make?
The CNC turning process is mostly ideal for cylindrical-shaped raw materials.
However, several manufacturers also use it for hexagonal and square-shaped workpieces.
It is a popular method for making machine parts for microfluidic tools, signage components,
surgical instruments, automotive frames, and aerospace parts.
4. Can you produce plastic turned parts?
Yes, our CNC turning services include plastic parts manufacturing. We can produce small or
large batch prototypes and production parts from various engineering-grade plastics.
Choose from our extensive range of plastic materials and upload your design file to get custom plastic components.
5. How about your quality?
Passed ISO9001 quality management system certification.
After the sample is approved, we will develop the operating instructions.
We will check 100% of the product before shipping.
