Five-axis machining centres have significant advantages over traditional three-axis machining equipment, especially in the machining of complex parts, accuracy and efficiency gains. The following are its main advantages:
1. Efficient machining of complex geometries
Multi-angle machining: Through the linkage of two rotary axes (e.g., A/B/C axis), the machining of five surfaces of a part can be completed in one clamping without repetitive positioning, which is especially suitable for complex curved parts such as aerospace blades, turbines, and automotive moulds.
Reduction of special fixtures: While traditional 3-axis requires multiple fixture adjustments, 5-axis can directly machine inclined surfaces or shaped structures by rotating the workpiece.
2. Higher machining accuracy
Reduced clamping error: one clamping to complete multi-face machining, avoiding the cumulative error caused by multiple clamping.
Optimal cutting angle of the tool: By adjusting the relative attitude of the tool and the workpiece, the tool is kept perpendicular to the machining surface, which reduces the side cutting edge of the tool and improves the surface quality.
3. Significantly improve production efficiency
Shorten process flow: Complex parts that originally required multiple machines to complete in separate processes can be machined by five-axis integration.
High-speed cutting ability: five-axis linkage can optimise the tool path, maintain a constant cutting speed, reduce empty cutting, machining efficiency increased by more than 30%.
4. Extend tool life
Optimised cutting conditions: Reduce tool wear by adjusting the tool tilt angle to avoid tip-centre cutting (in the case of 0 linear velocity).
Shorter tool overhang: rotating the workpiece or tool head brings the tool closer to the machining area, increasing rigidity and reducing vibration.
5. Cost reduction
Reduced equipment investment: replaces multiple 3-axis machines or specialised equipment.
Labour and time saving: high degree of automation reduces manual intervention and commissioning time.
6. Special function realisation
Side milling and deep cavity machining: tilting tool side edge machining of deep cavities or narrow grooves to avoid interference.
Profiling: High-precision profiling of complex surfaces such as impellers and propellers.
Typical application areas
Aerospace: engine blades, wing structural parts.
Medical devices: artificial joints, dental implants.
Energy equipment: turbine blades, hydraulic turbine parts.
Automotive moulds: complex stamping moulds, bumper moulds.
Limitations
High equipment cost: the price and maintenance cost of 5-axis machine is much higher than 3-axis.
Programming complexity: CAM software is required to support 5-axis path planning, requiring high operator skills.
Optimisation of machining strategies: Improper tool paths may lead to collisions or inefficiencies.
Summary
The core advantage of 5-axis machining centre lies in the ‘one-time forming of complex parts’ and ‘double enhancement of precision and efficiency’, which is suitable for the production of high value-added, small-lot complex parts. With the development of intelligent manufacturing, five-axis technology is becoming the standard for high-end manufacturing.
