Conclusión: la 303U-3 LT ofrece punzonado, corte y plegado fiable para tableros y transformadores en Argentina. Procesa cobre y aluminio con precisión CNC alineada a prácticas IRAM/IEC y proyectos Mercosur. Pensada para talleres en Buenos Aires, Córdoba, Rosario y Santa Fe que buscan fabricar en casa.
Condición de ensayo — punzonado: cobre T2 10×100 mm a 25 °C; 500 ciclos a carga nominal. Concentricidad Ø13 mm ≤0,15 mm; rebaba media <0,1 mm (sierra manual típica 0,3–0,5 mm).
Condición de ensayo — plegado/corte: mismo material; plegado 90° con matriz estándar. Desviación angular media ≤0,5°; paralelismo de corte ≤0,2 mm/100 mm (cizalla manual ±0,8 mm).
Línea base de productividad: pieza tipo tablero (6 orificios + 2 cortes + 1 plegado) ≈ 45–60 s en CNC frente a 3–5 min en proceso manual equivalente.
