Milling in CNC machining is a common precision processing method for aluminum, featuring high efficiency and high precision. When processing aluminum materials, a higher spindle speed (8000-12000rpm) and a larger feed rate are usually selected to fully leverage the advantages of aluminum materials such as softness and good thermal conductivity. The appropriate cutting depth is generally controlled between 0.5 and 3mm, which not only ensures processing efficiency but also controls surface quality. The use of alloy end mills or coated tools can further enhance the processing performance. This process is applicable to the manufacturing of large quantities of high-precision parts, such as in the automotive, aviation and electronics industries.
1.Common Machining Parameters for Milling Aluminum
Parameter Name | Typical Range | Description |
Spindle Speed (RPM) | 8000–18000 rpm | Suitable for aluminum due to its softness; high speeds are preferred. Related to tool diameter. |
Cutting Speed (Vc) | 300–1000 m/min | Depends on material and tool diameter. Higher speeds improve efficiency. |
Feed per Tooth (fz) | 0.05–0.2 mm/tooth | Proper feed improves efficiency and surface finish. |
Feed Rate (F) | Calculated by fz × number of teeth × RPM | Actual machine feed speed. |
Depth of Cut (ap) | 0.5–3 mm | Use smaller values for finishing, larger for roughing. |
Width of Cut (ae) | 20%–75% of tool diameter | Usually less than 50% for finishing; more for roughing. |
Tool Type | Carbide end mills, coated tools for aluminum, etc. | Polished or aluminum-specific coated tools are recommended. |
