Working Mechanism
The 3d galvo head is an advanced laser control mechanism used for precision material processing, engraving, marking, and 3D printing. It enables laser beams to move dynamically along three axes (X, Y, and Z), allowing for flexible and high-precision operations.
Components and Functionality
- X and Y Galvanometer Mirrors:
- Two high-speed galvanometer mirrors direct the laser beam in the X and Y directions.
- These mirrors are controlled by high-precision servo motors for rapid and precise beam positioning.
- Z-Axis Control:
- The Z-axis mechanism adjusts the focal length of the laser to maintain optimal focus on different layers or varying surface heights.
- This is achieved through either dynamic lens movement or adjusting the laser head height.
- F-Theta Lens or Dynamic Focusing Lens:
- Ensures a uniform focus over the entire scanning area.
- In 3D applications, a dynamic focusing system is used to adapt the focus dynamically across different depths.
- Control System:
- A digital signal processor (DSP) or field-programmable gate array (FPGA) controls the galvanometers and synchronizes movements across all three axes.
- Software integration enables real-time scanning adjustments based on CAD/CAM models or user-defined patterns.
Advantages of 3d Galvo Head
High-Speed and High-Precision Processing
- Galvanometer mirrors enable extremely fast beam movement, much faster than traditional CNC motion systems.
- Capable of reaching scanning speeds of several meters per second, ensuring efficient processing.
- Sub-micron precision, suitable for micro-machining applications.
3D Surface Adaptability
- The Z-axis adjustment allows laser scanning on uneven or curved surfaces, which is crucial for 3D engraving, additive manufacturing, and micromachining.
- Eliminates the need for repositioning the workpiece, enhancing automation and efficiency.
Large Working Area Without Mechanical Movement
- Unlike traditional CNC systems, the galvanometer scanner allows for a large working area without moving the workpiece, reducing mechanical wear and tear.
- Dynamic focusing allows processing beyond the traditional 2D flat field, expanding design possibilities.
Versatility in Applications
- Suitable for laser engraving, marking, cutting, micro-drilling, welding, and 3D printing.
- Compatible with various materials, including metals, plastics, ceramics, and glass.
