XT Laser-laser cutting machine

The reason why it is difficult to cut double-sided laminated materials is that the metal laser cutting head can only cut from the top of the plate, and the protective film on the plate does not work during the cutting process. However, due to the thin film on the bottom of the processed material, the cutting residue produced during the cutting process cannot be guaranteed to be completely reduced. These residues will directly affect the cutting quality of the plate, resulting in the inability to cut the plate or serious burrs after cutting.

However, if the protective film under the sheet is completely torn off, there may be scratches on the bottom surface of the sheet. Is there any way for the metal laser cutting machine to tear off all the film under the sheet and make the protective film not how it affects the cutting.

Why is it difficult for fiber laser cutting machine to cut double-sided laminated materials? The answer lies in the cutting position of laser cutting. The protective film at the bottom of the sheet does not affect the cutting quality. Only the protective film at the bottom of the cutting position affects the cutting quality, so just take off the protective film at the bottom of the cutting position.

Therefore, the main idea of double-sided cutting is to use the function of laser etching to find out the actual cutting position on the plate, then tear off the protective film at the cutting position, then turn the plate over and tear off the protective film at the cutting position. The front of the film is facing down, and finally cut with a laser cutting machine. To achieve this cutting method, the following steps are required:

Draw an auxiliary cutting diagram that matches the actual cutting diagram. The specific method is to mirror the actual cutting diagram and directly obtain the auxiliary cutting diagram.

Calculate the position and maximum offset of the film to be torn off. In theory, the protective film on the top of the sheet is etched by laser using the auxiliary cutting diagram, and then the sheet is turned over and cut directly. This is OK, but in the actual cutting process, due to the influence of laser positioning error and plate shape error, the cutting positions of the front and back of the plate cannot coincide, so the accurate offset must be calculated when etching the front. And tear off the offset protective film.

Draw cutting diagram and auxiliary cutting diagram. The cutting diagram can be drawn directly according to the shape of the workpiece. For auxiliary cutting diagram, first mirror the actual cutting diagram, and then offset with the set error value.

For the layout of the laser cutting diagram, the secondary cutting diagram should be set up first, and then the layout of the secondary cutting diagram should be mirrored. The etching line should be removed, and only the actual cutting diagram should be retained.

For laser cutting, the layout and etching shall be carried out first, and then the protective film shall be torn off at the position of the laser cut. After the protective film is torn off, the steel plate shall be turned over, and then the workpiece shall be cut.

The answer lies in the cutting position of laser cutting. The protective film at the bottom of the sheet does not affect the cutting quality, but only the protective film at the bottom of the cutting position. It affects the cutting quality.

So just take off the protective film on the bottom of the cutting position of the plate.

Due to the influence of laser positioning error and sheet shape error, the cutting positions of the front and back of the sheet cannot overlap. take advantage of sb . ‘s being in a weak position to overcharge him.

Draw cutting diagram and auxiliary cutting diagram. The cutting diagram can be drawn directly according to the shape of the workpiece. For auxiliary cutting diagram, first mirror the actual cutting diagram, and then offset with the set error value.
