Brief:Features:1. Special v-cut PCB board, stable operation mechanism, prevent improper external forces caused by PCB tin surface, electronic parts welding spot, and other electrical circuit due to the process of folding plate damage.2. Special round cutter material design ensures the smoothness of PCB surface.3. Fine adjustment of cutter wheel :0-2mm, lower plate knife can be adjusted :0-50mm4. Controllable five-stage adjustment of cutting travel distance, 0/100/200/300/400, quick switching between different PCB sizes.5. The height of upper knife can be adjusted according to plate and plate thickness to make more accurate cutting. The cutting thickness can be 0.6-3.0mm, and the remaining 1/3 of the thickness of standard V groove6. High-frequency eye protection lighting device to improve the operation quality of operators.
