CNC aluminum alloy processing machinery and equipment
CNC aluminum alloy processing mainly relies on the following machines and equipment:
CNC milling machine: used for cutting, drilling, milling and other processing of aluminum alloys. Usually three-axis, four-axis or five-axis CNC milling machines are used, and suitable equipment is selected according to the complexity of different parts.
CNC lathe: used for turning, cutting and finishing of circular parts of aluminum alloys.
CNC grinder: used for precision grinding of high-precision aluminum alloy surfaces to ensure the flatness and smoothness of the surface of parts.
Five-axis CNC Machining center: capable of cutting in multiple directions at the same time, especially suitable for processing aluminum alloy parts with complex shapes, which can greatly improve production efficiency.
CNC aluminum alloy processing technology
Precision cutting: CNC technology can accurately control the cutting depth and speed of aluminum alloy to avoid affecting the accuracy due to thermal expansion or deformation of the material.
Drilling and milling: Through CNC milling machines and drilling machines, holes, slots and complex geometric shapes of different specifications can be accurately processed.
Surface treatment: The surface of aluminum alloy often needs to be treated after CNC processing to enhance its corrosion resistance and aesthetics. Common surface treatment processes include anodizing, sandblasting, polishing, etc.
High-precision assembly: In some precision parts processing, CNC processing can not only complete the manufacture of a single part, but also assemble and debug parts to achieve higher precision requirements.
