3. Popular types of CNC machines
CNC lathes are one of the most common types of CNC machines, used to process round or cylindrical shaped parts. However, with the development of technology, CNC lathes are increasingly diverse in the number of axes, opening up more complex machining possibilities. In this section, we will learn about the most common types of CNC lathes, including 3-axis, 4-axis and 5-axis lathes.
3.1. 3-axis CNC lathe
- Working principle: 3-axis CNC lathe uses 3 main axes to perform machining operations: main axis (rotating the workpiece), sub-axis (feeding) and Z-axis (moving the tool vertically).
- Application: 3-axis CNC lathe is used to process simple shaped parts such as shafts, bearings, pulleys, threads…
- Advantages: Easy to operate, reasonable cost, suitable for large quantity production.

3.2. 4-axis CNC lathe
- Working principle: 4-axis CNC lathe adds one more rotation axis (usually B-axis) compared to 3-axis lathe, allowing machining of inclined surfaces and complex curves.
- Application: 4-axis CNC lathe is used to process parts with more complex shapes, such as fan blades, molds, etc.
- Advantages: Increased machining capacity compared to 3-axis lathes, reduced setup time.

3.3. 5-axis CNC lathe
- Working principle: 5-axis CNC lathe adds two more rotating axes (B-axis and C-axis) compared to 3-axis lathe, allowing machining of complex curved surfaces and freeform shapes.
- Application: 5-axis CNC lathes are used to process parts with extremely complex shapes, such as molds, aircraft parts, automobiles, etc.
- Advantages: Flexible machining capabilities, minimizing the number of cutting tools, improving production efficiency.

4. Comparison between 3-axis, 4-axis and 5-axis CNC lathes:
| Features | 3 axis lathe | 4 axis lathe | 5 axis lathe |
|---|---|---|---|
| Number of axes | 3 | 4 | 5 |
| Machinability | Simple | More complicated | Very complicated |
| Accuracy | High | Very high | Extremely high |
| Expense | Lowest | Higher | Highest |
| Application | Processing simple parts | Processing complex parts | Machining extremely complex parts |
Choosing the right CNC lathe:
Choosing the right CNC lathe depends on many factors such as:
- Type of material being machined: Different materials will require different types of lathes.
- Required Accuracy: Parts that require high accuracy will require a lathe with more axes.
- Part shape: Complex parts will require a lathe with more flexible machining capabilities.
- Product Quantity: High volume production will require a lathe with high speed and stable performance.
- Budget: The investment cost for a CNC lathe is also an important factor to consider.
