1. The beam emitted by the laser is tapered. Under this cone-shaped laser beam, the greater the thickness of the workpiece on laser die cutter, the lower the accuracy, so the larger the slit. When the cone-shaped laser beams are brought together, the smaller and smaller at this time, the precision of the laser cutting becomes higher and higher, especially the width of the slit becomes smaller and smaller. At this time the smallest spot can reach 0.01mm. This is also one of the factors that affect the cutting accuracy of laser die board cutting machine.

2. In this case, the material is different and the precision of laser die cutter is different. Even with the same material, the precision of the cut will vary if the composition of the material is different. Therefore, the workpiece material also has a certain influence on laser die board cutting machine accuracy.

3. The working surface of laser die cutter must also be flat, to ensure the accuracy, otherwise it will affect the cutting effect and reduce the precision.
