Briefly explained

What Is CNC Turning and How Does It Work? 

CNC turning is a precision machining process where a rotating workpiece—typically metal or plastic—is shaped by a computer-controlled cutting tool. This subtractive manufacturing method is essential in industries like aerospace, automotive, and medical device production

Key CNC Turning Operations

Common operations include:

  • Facing

  • Grooving

  • Threading

  • Taper turning

These are ideal for making cylindrical parts with tight tolerances.

Modern CNC Turning Machines

Advanced CNC lathes feature multi-axis machining (up to 16 axes) and integrated milling tools. They can cut complex features like:

  • Hex shapes

  • Threads

  • Wrench flats

This reduces setup time and improves efficiency.

Why CNC Turning Is Trusted

CNC turning is:

  • Accurate and repeatable

  • Fast and cost-effective

  • Used in high-stakes industries

It’s a reliable choice for high-volume production or custom prototyping.

Swiss-Type CNC Turning: Precision Meets Automation


Swiss-type CNC turning is a highly advanced machining process designed for producing complex, high-precision parts—especially in industries like medical, aerospace, and electronics

What Is Swiss-Type CNC Turning

Originating in Switzerland and widely adopted in Japanese manufacturing, Swiss-type CNC lathes are known for:

  • Automatic feed systems

  • Up to 20 axes

  • 6-sided cutting capabilities

These machines combine turning, milling, and drilling in a single setup, allowing for continuous, hands-off production of intricate components.

Benefits of Auto-Feed CNC Turning

Modern Swiss-type lathes use auto-feed mechanisms to:

  • Reduce manual intervention

  • Improve machining consistency

  • Increase cycle efficiency

  • Handle complex geometries and tight tolerances

This automation makes them ideal for high-volume production of small, detailed parts.

Trusted Technology in Precision Manufacturing

From real-world shop floor experience, Swiss-type turning has proven to be extremely reliable and versatile. Whether you're running medical implants, watch parts, or high-performance connectors, this technology delivers unmatched precision.

Hi Alice, 

Just want to say your outstanding service is super impressive. Your great job on our stainless steel bending case makes our espresso coffee grinder added value. It really makes it look nice, super well done.


Aline Turner, SR procurement


Hi Alice,

We would like to say thank you to you Alice, DMS delivered our parts very fast with excellent quality that is what we are expecting, hopefully you will see our next order very soon, by the way Alice, please say hi to Jennifer for me.  


Iris Joe, Engineering Designer


Dear Alice, 

Now I can say it is a right decision to move our production from China to DMS, you guys are awesome, all the marine pads looks shinny no scratch founded, it is 8% more expensive compare to China but quality talks, we will keep buying more items from you for sure.
