Las dobladoras manuales ganan solo para prototipos, one-offs y talleres de baja mezcla. El cruce de ROI es t\u00edpicamente de 8 - 14 meses, porque el CNC elimina la chatarra del adelgazamiento de la pared inconsistente, elimina el cuello de botella del operador experto y mantiene la repetibilidad de \u00b1 0.2 mm que la flexi\u00f3n manual no puede.<\/p>\n<h2>1. Uniformidad de pared: la diferencia decisiva<\/h2>\n<p>Manual rotary bending relies on the operator’s feel for speed, pressure, and mandrel position. That varies bend-to-bend, so wall thickness thins unevenly — a failure risk on pressure or structural tubes. A CNC bender drives every axis from a program, so wall thinning stays within spec every time.
