Laser relief technology predates additive manufacturing and is popular in industries such as jewelry processing, die engraving and coin minting. Laser relief is a typical laser subtractive manufacturing technology, this technology is used to remove layers of a complete piece of material by laser to achieve three-dimensional laser engraving.
Compared to traditional tool engraving and EDM, the laser relief process is directly 3D digital modeling, and the laser reduction process is controlled by a dynamic focus system to achieve what you see is what you get. Laser processing accuracy and efficiency, no residual mechanical stress, can achieve smaller size micro engraving, etc., in the field of precision processing in a wide range of applications.
In the 3D laser processing relief process, from the 3D dynamic focusing system of this component to share with you the following points:
1. Ukiran dokumen jenis
In laser relief requires the use of 3D model drawing (STL format) document. You can use 3D digital modeling in the marking software, or 3D model drawing (STL format) directly into the marking software, slicing generation, you can carve out the effect of 3D relief.
2. Process characteristics
Wide application: Most of the metal and non-metal materials can be used for relief engraving, such as copper, aluminium, abrasive steel, silicon carbide, jade, wood, etc. The laser spot is finer than the knife, and the processing can be finer. Therefore, laser relief processing is widely used in crafts industry, special industry, mold industry, etc.
Tinggi kecekapan: The laser relief equipment loaded with dynamic focusing system. When working, the 3D dynamic axis of dynamic focus is in full software synergy with the XY axis, and the layered focus compensation is done in microseconds, which is highly efficient. In the right configuration, it is possible to meet or exceed the efficiency of CNC.
High precision: By controlling laser subtractive processing through dynamic focus system, it can adjust the focal distance with the increase of processing layers, and adjust the spot in real time with the dynamic axis synergy, which can ensure the focal spot software controllable during the whole processing process, and can obtain higher precision compared with the traditional oscillator.
3. How to debug the best effect
Before laser relief ukiran menandakan parameters, filling line spacing, layer ketebalan dan other parameters need to test the most appropriate parameters.
Layered ketebalan: Using the filling parameters derived from the material test, the layered thickness of the relief is derived by carving the material 50 to 100 times, total depth/carving times=depth of a single process.
Switching light delay time: Test on actual samples and repeatedly test until the surface of the relief is smooth to derive the appropriate opening light delay time parameters.
Cleaning: There will be dust in the relief carving process, which needs to be cleaned every 3-5 layers of carving, otherwise the dust will accumulate too much and cause the relief to be unshaped.
