钣金加工机箱外壳是一种对金属板材进行冷加工的加工工艺，包括剪切、冲压、切割、折叠、焊接、铆接、拼接、成型等工序。这种加工工艺具有速度快、成本低、强度高的特点。它可以大规模生产加工出来的钣金机箱外壳件精度高。
Sheet metal processing chassis casing is a cold processing process for metal sheets, including shearing, stamping, cutting, folding, welding, riveting, splicing, forming, and other processes. This processing technology has the characteristics of fast speed, low cost, and high strength. It can produce and process sheet metal chassis shells with high precision on a large scale.
用于加工金属板底盘外壳的剪切机是将金属板切割成所需的形状。该工艺精度一般，切割时会有毛刺，但加工成本低。剪切过程需要计算零件的展开尺寸。展开尺寸与弯曲半径、弯曲角度、板材、厚度等有关。
The shearing machine used for processing the metal plate chassis shell is to cut the metal plate into the desired shape. The accuracy of this process is average, and there may be burrs during cutting, but the processing cost is low. The cutting process requires calculating the unfolded size of the part. The unfolding size is related to bending radius, bending angle, sheet metal, thickness, etc.
冲压是钣金加工机箱外壳的工艺中一种冲压工艺，是对切割后的材料进行进一步加工成型。冲压需要多种工具。普通磨床有圆孔、长圆孔和凸台，冲压加工精度高。经过加工钣金零件非常漂亮。
Stamping is a stamping process in the process of sheet metal processing of the chassis casing, which further processes and shapes the cut material. Stamping requires multiple tools. Ordinary grinding machines have round holes, long round holes, and convex tables, with high stamping accuracy. The processed sheet metal parts are very beautiful.
钣金加工机箱外壳折叠是弯曲，使用折弯机或弯板机进行弯曲成型，通过折弯机的上刀和下刀对金属板进行冷压，使其变形并获得所需的形状。弯曲是金属板成形的一步。
The folding of the shell of the sheet metal processing chassis is bending, which is formed using a bending machine or bending machine. The metal plate is cold pressed through the upper and lower blades of the bending machine to deform and obtain the desired shape. Bending is a step in forming metal plates.
切割是激光切割。当切割不能通过切割和冲压工艺去除的材料时，或者具有较大硬度的板容易损坏研磨工具，例如圆角，或者没有现成的研磨工具来冲压成所需的形状时，可以使用激光切割来在弯曲之前完成成形材料的成形。钣金加工机箱外壳使用这种加工方法精度高，无毛刺，可以切割任何图形。
Cutting is laser cutting. When cutting materials that cannot be removed through cutting and stamping processes, or when plates with high hardness are prone to damage to grinding tools, such as rounded corners, or when there are no readily available grinding tools to press into the desired shape, laser cutting can be used to complete the formation of the formed material before bending. The shell of the sheet metal processing chassis uses this processing method with high accuracy, no burrs, and can cut any shape.
焊接是加工弯曲和成形的金属板零件。焊接后，钣金加工机箱外壳的强度会增强。
Welding is the processing of bent and formed metal sheet parts. After welding, the strength of the sheet metal processing chassis casing will be enhanced.
