STE‑200 (closed-type two-point) vs ST‑200 (open-type single point):
- STE‑200: Closed gantry, high rigidity, high precision, suitable for large-area/continuous dies
- ST‑200: Open C-type, cost-effective, large operating space, suitable for small and medium-sized parts
Typical Configuration: Material Rack (MT‑200) → Leveler (SML‑400 or STL‑400) → NC Servo Feeder (NCF‑400) → STE‑200 Punch Press → Material Receiving Device/Manipulator
