Sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing, punching/cutting/compounding, folding, riveting, splicing, forming, etc. Its notable feature is the uniform thickness of the same part. The basic equipment of sheet metal technology includes a shearing machine, CNC punching machine, laser, plasma, water jet cutting machine, bending machine, drilling machine, and various auxiliary equipment. In addition, custom metal fabrication services provide metal processing with aluminum sheet metal fabrication, stainless sheet metal fabrication, and titanium sheet metal fabrication, etc.
Sheet metal processing can quickly process aluminum alloy plates and cemented carbides and can cut without deformation no matter how high the hardness is. And its processing flexibility is very good, not only can process any kind of graphics but also can cut pipes and other strange-shaped materials. And most non-metallic materials can also be cut quickly and efficiently, so CNC sheet metal fabrication will not be restricted by any material properties.
The most significant advantage of sheet metal processing technology is the fast cutting speed, and it will not be limited by the number of processing. However, the sheet metal cutting service is more suitable for the processing of special-shaped workpieces in the process of processing because it does not need to waste time to replace the tool, which effectively increases the processing speed; to a certain extent, its processing speed and maximum positioning speed are lower than the speed of wire cutting.
Laser cutting in sheet metal processing belongs to non-contact cutting, and its cutting edge is affected by heat to a small degree, which can avoid the adverse effect of thermal deformation of the workpiece. Moreover, it can completely avoid the collapse of the material when the material is punched and cut. Generally, the cutting seam does not require secondary processing, which improves the work efficiency to a certain extent; not only that, its cutting head will not contact the material surface, thus efficiently ensure that the workpiece is not scratched.
