In the world of CNC machining, two processes stand out as the foundation of modern manufacturing: CNC Milling and CNC Turning. While both deliver outstanding precision, they are very different in terms of operation, applications, and part design.

Understanding these differences will help you choose the right machining service for your project—whether it’s for aerospace, UAV, automotive, or medical applications.

What is CNC Milling?

CNC Milling uses a rotating cutting tool that moves across a stationary workpiece to remove material. This method allows for highly complex shapes and multi-axis operations.

Key Advantages of CNC Milling:

- Handles complex geometries and contours
- Perfect for creating slots, holes, and detailed features
- Supports a wide range of materials: aluminum, magnesium, titanium, plastics
- Excellent for low-volume prototyping and high-volume production

Typical Applications:

• Aerospace components
• UAV magnesium housings
• Automotive brackets and engine parts
• Medical device components

 What is CNC Turning?

CNC Turning works differently—it rotates the workpiece while a stationary cutting tool removes material. This process is best for cylindrical or symmetrical shapes.

Key Advantages of CNC Turning:

- High precision for round parts
- Faster for producing tubes, rods, shafts
- Excellent for threading and surface finishing
- Works well with steel, brass, aluminum, and titanium

Typical Applications:

• Shafts and rods
• Bushings and couplings
• Screws, bolts, and threaded parts
• Drone propeller hubs

 CNC Milling vs CNC Turning: Side-by-Side Comparison

 Which One Should You Choose?

Choose CNC Milling if your part is complex, angular, or requires multiple features.

Choose CNC Turning if your part is round, threaded, or requires symmetry.

Many industries combine both processes to achieve the best balance of precision, cost-efficiency, and speed.

 Real-World Example from JYH Precision Machining

At JYH Precision Machining, we frequently manufacture UAV magnesium parts where:

• The housing is milled for precise cutouts and lightweight structure.
• The shafts are turned for flawless rotation.

This combination ensures strength, accuracy, and durability for demanding aerospace applications.

CNC Milling and CNC Turning are complementary processes that power industries like aerospace, automotive, UAV, and medical technology. By choosing the right machining method—or combining both—you can achieve unmatched accuracy and performance for your project.

At JYH Precision, we specialize in 5-axis CNC milling, CNC turning, low-volume prototyping, and precision machining across a wide range of metals and plastics.
