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 Our 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.
We may not be perfect, but our work is honest and results are true.
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.
