2025-01-10
1. Definition and Motion Method
-
Pure 5-axis machine tool
A pure 5-axis machine tool refers to a machine where the five axes between the tool and the workpiece can move continuously and synchronously. These five axes typically consist of three linear axes (X, Y, Z) and two rotary axes (A, B, or C).- The tool always maintains the optimal cutting angle with the workpiece.
- Suitable for complex surfaces or continuous angle processing.
-
3+2-axis machine tool
A 3+2-axis machine tool is a three-axis machine with rotary axes. The two rotary axes are used to fix or adjust the angle of the workpiece, while the main processing occurs through the X, Y, and Z axes.- The workpiece is adjusted to the correct angle before processing, and then processed in a fixed posture.
- Suitable for parts that require multi-surface processing, but with limited surface processing capability.
2. Processing Capability
-
Pure 5-axis machine tool
- Capable of high-precision processing of complex surface parts, such as turbine blades and aerospace components.
- Achieves high dynamic cutting and reduces transition time.
- Can complete most processing in one operation, improving production efficiency.
-
3+2-axis machine tool
- Mainly used for multi-surface processing, requiring frequent angle changes but not continuous angle variation.
- Weaker processing capability for complex surfaces, mainly used for more regular parts.
3. Precision and Flexibility
-
Pure 5-axis machine tool
- More flexible, able to adjust the relative position of the tool and workpiece in real-time to maintain optimal cutting conditions.
- Higher requirements for programming and control.
-
3+2-axis machine tool
- Relatively simple, with more fixed cutting paths.
- More suitable for workpieces with lower precision requirements or processing scenarios with fewer surfaces.
4. Cost and Complexity
-
Pure 5-axis machine tool
- Complex equipment, high price, and higher maintenance and operation requirements.
- Programming requires professional CAM software and technical personnel support.
-
3+2-axis machine tool
- Lower cost than pure 5-axis machine tools, existing three-axis machines can be upgraded to achieve this.
- Programming is relatively simple, but may require multiple clamping.
5. Application Scenarios
-
Pure 5-axis machine tool
- High-end manufacturing fields, such as aerospace, automotive, and energy.
- Processing of complex geometric shapes or continuous surfaces, such as turbine blades and molds.
-
3+2-axis machine tool
- Multi-surface processing, but for workpieces with lower geometric complexity.
- Small to medium batch production, cost-effective processing tasks.
