钣金加工通常是指是对金属薄板（厚度≤6mm）一种综合冷加工工艺，大致有剪、冲、折、焊、铆等工序，其显著特征就是同一个加工件厚度一致，加工对象多为钢板、铝板等金属板材

钣金加工过程中常用设备包括剪板机、数控冲床、激光切割机、折弯机、焊机、以及辅助设备（刨槽机、切角机、校平机、去毛刺机）等。

Sheet metal processing usually refers to a comprehensive cold working process for sheet metal (thickness ≤ 6 mm), which roughly includes shearing, punching, folding, welding, riveting and other processes. Its remarkable feature is that the thickness of the same workpiece is the same, and the processing objects are mostly steel plate, aluminum plate and other metal plates

Commonly used equipment in sheet metal processing includes plate shears, CNC presses, laser cutting machines, bending machines, welding machines, and auxiliary equipment (planing machine, corner cutting machine, leveling machine, deburring machine), etc.
