Conclusión: la 303U-3-C LT ofrece CNC 3 funciones para transformadores 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.

Product Description
Main Features
1. The shearing/cutting unit adopts double column shearing dies.
2. The punching unit is an integral six-mode turnplate, which ensure the upper and lower molds are absolutely in the center.
3. The bending unit adopts a closed bending structure, which makes it more uniform during processing horizontal bending and embossing, and improves the repeat positioning accuracy in mass production.
4. Different molds or tools can be installed according to user requirements to complete special shape processing.
