NTG-20
V-CUT/Pre-scored PCB Depaneling Machine - Moving Blade
V-CUT走刀式分板機
The NTG-20 is a motorized linear-blade V-cut PCB depaneling machine featuring a stationary lower flat blade and an electric traversing circular upper blade. Keeping the PCB stationary during cutting minimizes internal tensile stress to prevent micro-cracks in sensitive SMD components (cut length up to 400 mm).

【Key Machine Features & Advantages】
- Moving-blade pre-scored V-CUT PCB depaneling machine engineered with a zero-bending-stress philosophy for both short and long PCBs.
- Stationary PCB cutting method: the board remains perfectly flat and stationary while the upper ψ 145 mm round blade rolls across, eliminating drag stress and joint micro-fractures.
- Standard high-intensity work illumination lamp (YES included) significantly improves groove alignment accuracy and operational safety.
- Bi-directional adjustable stroke: maximum cutting stroke reaches up to 400 ~ 430 mm, supporting rapid back-and-forth passes (left-to-right and right-to-left).
- Powered by a high-efficiency D.C. brushless IPM motor with a front-panel VR potentiometer (0 ~ 100 scale), delivering blade speeds up to 500 mm/sec.
- Clearance and edge margins: permits components up to 20 mm on the top side and 10 mm underneath; requires a minimum 2 mm margin from component to V-groove edge.
- Heavy-duty tooling: upper moving round blade paired with a lower 500 mm rigid straight rail blade, both precision-calibrated and capable of multiple re-sharpenings.
- Supporting platform is vertically adjustable to align flush with the lower blade; custom clearance milling available for groove-crossing parts. (Note: Belt conveyor model NTG-20-NS is discontinued; standard NTG-20 is active).
