Discover Leading 4-Axis CNC Machining Services Near You: Precision, Efficiency, and Affordability
1. What is 4-Axis CNC Machining?
Definition: 4-axis CNC machining utilizes three linear axes (X, Y, Z) and one rotary axis (commonly the A-axis) to perform multi-angle cutting. This configuration is ideal for producing complex yet efficient parts without the need for five-axis linkage.
Core Advantages:
- Multi-Faceted Machining: Achieve features such as cylinders, bevels, and spiral grooves in a single setup.
- Cost-Effectiveness: More affordable than five-axis equipment, reducing the need for multiple setups compared to three-axis machining.
- Typical Applications: Automotive camshafts, aviation brackets, and medical implant bases.
2. 4-Axis vs 3-Axis vs 5-Axis: How to Choose?
| Comparison Dimensions | 3-Axis | 4-Axis | 5-Axis |
|---|---|---|---|
| Motion Axis | X, Y, Z | X, Y, Z + A (rotation axis) | X, Y, Z + A, B/C (double rotation axis) |
| Processing Complexity | Plane, simple surface | Cylinder, spiral structure | Free-form surface, aviation impeller |
| Cost | Low | Medium | High |
| Applicable Scenarios | Sheet metal, basic parts | Drive shaft, gearbox | Turbine blades, complex molds |
3. Core Applications of 4-Axis CNC Processing
| Industry | Typical Parts | Material | Accuracy Requirements |
|---|---|---|---|
| Automobile Manufacturing | Camshaft, connecting rod | Alloy steel, aluminum alloy | ±0.02 mm |
| Aerospace | Bracket, hydraulic components | Titanium alloy, composite material | ±0.01 mm |
| Medical Equipment | Joint implant base | Stainless steel, PEEK | Ra 0.8 μm surface finish |
| Industrial Equipment | Gear, drive pulley | Brass, nylon | ±0.05 mm |
