Before using sapphire laser cutting machine for work, we will import the prepared drawings into the program, and then use the typesetting software to arrange the graphics on a board, so that the laser cutting machine can process the products in batch. Do we have any precautions during these operations?
1. Corner melting
When cutting corners of thin panels at reduced speed, the laser will melt the corners due to overheating. A small radius is generated at the corner to maintain the high-speed laser cutting and avoid the overheating and melting of steel plate when cutting the corner, so as to obtain good cutting quality, reduce cutting time and improve productivity.
2. Part spacing
In general, when cutting thick plates and hot plates, the spacing between parts should be large, because the heat of thick plates and hot plates has a great impact. When cutting corners, sharp corners and small graphics, it is easy to burn edges, affecting the cutting quality.
3. Leader settings
In the process of cutting thick plates, in order to make the cutting seam connect well and prevent burns at the beginning and end, a transition line is often led at the beginning and end of cutting, which are called lead and tail line respectively. The lead and tail line are useless to the workpiece itself, so they should be arranged outside the scope of the workpiece. At the same time, pay attention not to set the lead at sharp corners and other places that are not easy to heat dissipation. The connection between the lead and the slit shall adopt arc transition as far as possible to make the machine move smoothly and avoid burns caused by corner pause.
4. Common edge cutting
Two or more kinds of parts are combined into a combination, and a large number of regular graphics share the same edge as much as possible. Common edge cutting can greatly shorten the cutting time and save raw materials.
5. Part collision
Many laser cutting equipment operate continuously for 24 hours, and use unmanned automatic loading / unloading device to hit the overturned parts after cutting, resulting in cutting head damage and production interruption, resulting in great losses. This requires attention when sorting:
① Select appropriate cutting path and bypass the cut parts to reduce collision.
② Select the cutting route to reduce the cutting time.
③ Automatically or manually combine multiple small parts with micro connection. After cutting, the removed parts can easily disconnect the micro connection.
6. Residual material treatment
After cutting the material, the skeleton like residual material on the workbench of the laser cutting equipment needs to be removed as soon as possible to facilitate the subsequent cutting operation. For laser cutting equipment without automatic unloading device, the skeleton residual material can be cut into small pieces to facilitate rapid removal. Thus, personal injury caused by moving heavy and sharp edge surplus materials is avoided.
