Board cutting

1. For board cutting, the laser machine has the best effect;

2. Polishing effect: flat without deformation;

3. The card slot is smooth without burr and easy to fix;

4. If the seam is too large, it is easy to see the welding scar on the front (if both sides are welded, the welding and grinding are not easy to handle). It is suggested to reduce the space and fix it directly, so it will be easy to assemble, spray and have good decorative effect;

5. After welding, polish to ensure spraying effect. Too much weld will affect the overall beauty effect;

6.If the tower punch is used, there will be displacement and straightness in the post production process;If the engraving machine is used, the position angle of the slotting card is round corner, which can not reach the precision, which will lead to the uneven board surface, poor polishing effect, delay of spraying process, decline of the overall quality of the product, and finally delay the whole construction period and delivery time.
