Advantage
In five-axis engraving machines, the table dynamic structure is a common design method, especially widely used in small and medium-sized five-axis equipment. Compared with the gantry moving or spindle moving structure, the table dynamic structure has the following significant advantages:
1. Stronger structural stability
Low center of gravity and good rigidity: The table moving structure usually fixes the workpiece on the workbench, and the entire table moves along the X-axis or Y-axis. The center of gravity is low and the movement is smoother, which is suitable for high-precision processing.
Excellent anti-seismic performance: As the workbench moves, the spindle and the crossbeam remain fixed, reducing the inertial impact caused by the movement of the spindle and improving the processing stability.
2. Higher processing accuracy
Reduced mechanical error: The moving axis of the table dynamic structure is less concentrated in the spindle part, reducing the linkage error, which is particularly suitable for the processing of high-precision molds, crafts, and complex surfaces.
High repeat positioning accuracy: Due to the stable structure, combined with the high-precision servo system and guide rails, the repeat positioning accuracy can reach ±0.02mm or even higher.
3. Suitable for processing small and medium-sized workpieces
The workpiece is firmly fixed: the workpiece is fixed on the moving table, the fixture design is simple, and the clamping is convenient, which is suitable for batch processing of small and medium-sized parts.
High utilization of processing space: compact structure, small equipment footprint, suitable for workshops or laboratory environments with limited space.
4. Easier maintenance and operation
Easy maintenance: the spindle and beam are fixed, which is convenient for daily maintenance and maintenance, and reduces the wear caused by the movement of the spindle.
Intuitive operation: the workpiece moves with the table, and the operator can more easily observe the processing process, which is convenient for debugging and monitoring.
5. More cost-effective
The manufacturing cost is relatively low: compared with the gantry movement or spindle movement structure, the mechanical complexity of the table movement structure is lower, and the manufacturing cost and maintenance cost are more controllable.
High cost performance: especially suitable for users with dual requirements for precision and cost such as small and medium-sized enterprises, universities, and research institutes.
