Machined parts and sheet metal parts are two common parts in the manufacturing industry. They are different in processing methods, processing materials, processing technology and application fields.
Different processing methods
Machined parts are generally processed by processing metal raw materials into the required shape and size, mainly using CNC machine tools, lathes, drilling machines, milling machines and other mechanical equipment for processing; while sheet metal parts are formed into the required shape and size through a series of processing procedures such as cutting, bending, stamping, and stretching of metal sheets.
Different processing materials
The processing materials of machined parts are usually blanks, that is, whole pieces or bars of metal raw materials, including iron, copper, aluminum, stainless steel, etc.; while the processing materials of sheet metal parts are usually metal sheets, including cold-rolled plates, hot-rolled plates, stainless steel plates, etc.
Different processing technology
The processing technology of machined parts is generally processed by cutting, drilling, milling, turning and other processes, which requires multiple processes and is relatively complicated; while the processing technology of sheet metal parts is generally processed by cutting, bending, stamping, stretching and other processes, which generally only requires a few processes and is relatively simple.
Different application fields
Machinery parts are mainly used in precision machinery, automobiles, rail transportation and other fields, such as engine cylinders, bearings, gears, etc.; while sheet metal parts are mainly used in construction, electronics, communications, home appliances and other fields, such as refrigerator shells, air conditioner shells, TV shells, chassis, etc.
