Both machines bend sheet metal, but they belong to different leagues. A sheet metal brake is a simple folding tool for light, straightforward work. A press brake is an industrial machine for precise, repeatable production across a wide range of thicknesses. Knowing where one ends and the other begins keeps you from overpaying or outgrowing your equipment.
A sheet metal brake clamps a sheet and folds it upward along a straight line. The common types are the cornice or leaf brake for simple folds, and the box-and-pan (finger) brake, whose removable fingers let you form four-sided boxes and pans. These are mostly manual, affordable and great for thin material, prototypes and HVAC or sheet-metal trade work. Their limits are thickness, precision and throughput.
A press brake drives a punch into a V-die to form each bend. In hydraulic and CNC versions it handles thick material, complex profiles and tight tolerances, with a motorised backgauge and angle control that make every part match the last. It costs more and needs a trained operator, but it is the backbone of real fabrication. It is the heart of the VICLA press brake range.

Reach for a sheet metal brake when you fold thin material in small quantities, build simple boxes or pans, or need a cheap, portable tool on site. Move to a press brake when precision, repeatability, thickness or volume matter, or when you bill for the parts you make. The tell is when inconsistent angles start creating scrap: that is when a press brake pays for itself.
For simple work yes, but repeatability across many parts is its ceiling.
Not if you need accuracy or thicker material. Compact models exist for exactly this.
Rarely. A press brake covers everything a sheet metal brake does and much more.
