What are the most common problems in CNC milling of aluminum?
Aluminum is the most commonly used metal in CNC machining. Due to its excellent physical properties, aluminum accounts for approximately 80% of all non-ferrous metal machined parts in the aerospace, semiconductor, and robotics industries.
Even on modern CNC machining centers, errors can occur in the precision CNC milling of aluminum if the process technology and temperature control are inadequate. Three of the most common problems are:
1. Overcutting: When milling deep into the workpiece, if the tool is too long and the spindle speed cannot reach high enough, overcutting can occur.
2. Temperature effects: Due to the principle of thermal expansion and contraction, complex workpieces need to be milled in a temperature-controlled workshop environment.
3. Edge burrs: – Burr problems are more prominent in custom CNC milling of aluminum parts, especially on parts with intersecting holes or internal threads.
4. Stress Effects: Stress can cause deformation in processed products, leading to defective parts. Therefore, for complex products, we need to rough-cut the surface first, then allow it to rest for about 24 hours to fully release stress before proceeding to the second step, finishing. This will increase processing time.
