Sheet metal generally defines its said: sheet metal is for sheet metal (usually in under 6 mm), an induction cold working process including cutting, punching/cut/composite, folding, welding, riveting, joining together, forming (such as car body). Its prominent feature is the same thickness of parts together.

About sheet metal processing, a brief explanation is sheet metal processing is aimed at a plate type material, for example, steel plate, galvanized sheet and their bending, shear, or into the shape of a specified stamping processing, such as circular parts, arc accessories such as hardware, such as the commonly used shearing machine, bending machine, and punching machine.

Mechanical processing is more complicated compared with sheet metal processing, mainly processing parts, or all the data are generally patches, but also a plank. Mainly is to use professional processing machines for cutting, general now use lathe, milling machine, grinding machine, line cutting, CNC, spark machine and other processing equipment.

Sheet metal processing and brief it is sheet metal processing, such as computer chassis, power distribution box, use of machine tool is usually CNC punch press, laser cutting, bending machine, shearing machine, etc. But the machining is not the same as sheet metal processing and it is processed into hair sheet metal parts, for example axial is machined metal parts.
