Product Overview: ST-NN500 PRO
The ST-NN500 PRO combines heavy-duty construction with modern digital control. Featuring a responsive LCD touchscreen and a powerful pneumatic active clamping system, it delivers intelligent, high-speed CNC nailing for professional frame assembly.
Core Features: Smart Framing with NN500 PRO
- Intelligent Touchscreen Control
Upgraded from the standard NN400, the NN500 features a responsive LCD touchscreen. This allows operators to input nail positions visually, store frame data, and switch between profiles instantly without manual recalibration. - Active Clamping System (Downward Pressure)
Features a powerful pneumatic cylinder that applies active downward pressure. This ensures the frame corner is held firmly against the table before nailing, eliminating gaps even on warped wood. - High-Speed CNC Nailing
Driven by a nine-stage CNC system, it can perform 5-nail stacking and 9-row synchronized nailing in one pass. This flexibility handles complex moulding shapes with ease. - Multi-Material Versatility
The smart pressure adjustment makes it suitable for joining solid wood, MDF, foam, and plaster molding strips without damaging delicate surfaces.

Frequently Asked Questions (FAQ)
Q: What is the main upgrade of NN500 compared to NN400?
A: While both machines use the stable “Active Clamping” system, the NN500 adds a Touchscreen interface. This allows you to save frame settings and visualize the nailing process, whereas the NN400 relies on standard controls.
