If many metal materials want to maintain their integrity, special treatment is required. Otherwise, they are easily scratched in many transportation projects. It is very difficult to process parts with high material requirements. Therefore, many metal materials are covered by films. Metal lamination can ensure that friction damage of raw materials, such as aluminum alloy doors and windows, furniture, kitchenware, etc., will be minimized during transportation. The sales of these products are very important for their own sales, and scraping is not allowed, which has higher requirements for laser cutting machine to cut metal. Can laser cutting machine cut coated metal?

It is difficult to cut the laminate because the cutting head can only be cut from the top of the laminate, and the protective film on the top of the laminate has no effect on the cutting process. However, because the film is pasted on the bottom of the sheet, the cutting residues generated during the cutting process cannot fall completely, which will directly affect the cutting effect of the sheet, so the sheet cannot be cut through or cut. The burr is very big, but if you tear off all the film under the printing plate, there will be scratches under the printing plate. How does the laser cutting machine cut the coated metal?

Can laser cutting machine cut coated metal?

The specific methods are:

1. Draw the auxiliary cutting diagram matching the actual cutting diagram. The specific method is to mirror the actual cutting diagram, and then you can directly obtain the auxiliary cutting diagram.

2. Calculate the position and maximum deviation of the film to be removed. In theory, using the auxiliary cutting diagram to etch the top of the board by laser can remove the protective film at the cutting position, and the board can be directly cut by turning over. However, in the actual cutting process, due to the influence of laser positioning error and sheet shape error, the cutting positions of the front and back of the sheet cannot coincide. It is therefore necessary to measure the exact offset and pull off the protective film at the offset.

3. Prepare 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 compensate with the set error value.

4. Perform laser cutting layout. First of all, you need to set up an auxiliary cutting diagram. Secondly, the layout images of the auxiliary cutting diagram and etched lines are removed, and only the actual cutting diagram is retained.

5. Perform laser cutting. First, the plate is etched, and then the protective film at the laser notch is removed. After tearing off the protective film, turn the steel plate over and start cutting the workpiece.
