Machining andSheet metal processingThere are significant differences in several aspects, here is a detailed comparison:

1. Definition and processing methods

1. Machining

   • Full name mechanical processing, refers to a manufacturing process that precisely changes the shape, size, or performance of a workpiece through mechanical equipment.
   • Mainly utilizes machine tools and other mechanical equipment to process raw materials or parts into finished products of the desired shape and size through cutting, drilling, milling, grinding, and other processes.

2. Sheet metal

   • A processing method for metal materials, referring to a process of processing, making, and assembling metal sheets to obtain the desired shape and size.
   • Mainly processes metal sheets into parts or components of the desired shape and size through cutting, bending, stamping, stretching, welding, and other procedures.

2. Processing materials and equipment

1. Machining

   • Processing materials: Blanks, including whole pieces or bars of metal raw materials such as iron, copper, aluminum, stainless steel, etc.
   • Processing equipment: CNC machine tools, lathes, drilling machines, milling machines, and other mechanical equipment.

2. Sheet metal

   • Processing materials: Metal sheets, such as cold-rolled sheets, hot-rolled sheets, stainless steel sheets, brass sheets, etc.
   • Processing equipment: Stamping machines, bending machines, shearing machines, welding machines, etc.

3. Processing technology and precision

1. Machining

   • Processing technology: Multiple processes such as cutting, drilling, milling, and turning, the process is relatively complex.
   • Processing precision: Usually at the micron level, suitable for parts processing with high precision requirements.

2. Sheet metal

   • Processing technology: A few processes such as cutting, bending, stamping, and stretching, the process is relatively simple.
   • Processing precision: Generally at the millimeter level, suitable for parts processing with relatively low precision requirements.

4. Applications

1. Machining

   • Mainly applied in fields such as precision machinery, automotive, rail transportation, aerospace, etc., such as engine cylinder blocks, bearings, gears, etc.

2. Sheet metal

   • Widely used in fields such as construction, electronics, communications, home appliances, etc., such as refrigerator housings, air conditioning housings, television housings, computer cases, etc.

In summary, machining and sheet metal processing have significant differences in definitions, processing methods, processing materials and equipment, processing technology and precision, as well as applications. In practical applications, it is necessary to choose the appropriate processing method based on specific needs and conditions.
