aluminium cnc machining

The manufacturing of aluminum parts is an important application field in CNC machining. Under the premise of aluminum material, the following factors need to be considered:

1、 Force majeure factors:

The stability of the machine tool itself: The stability of the machine tool may affect the dimensional accuracy of the aluminum parts manufactured. Common influencing factors include looseness between the servo motor and the screw, wear of the ball screw bearing or nut, and insufficient lubrication between the screw and nut.

Cooling deformation of workpieces after processing: Aluminum is a material that expands and contracts with heat, and the processed aluminum parts may experience cooling deformation. This is a factor that needs to be noted during the processing process.

2、 Avoidable factors:

Leave a small margin: Do not excessively cut aluminum material during processing to avoid excessive machining that may lead to a decrease in part accuracy.

The three elements of cutting: cutting speed, feed rate, cutting depth, and tool compensation are also important factors that affect the machining accuracy of aluminum parts. Adjusting these parameters can improve cutting efficiency and reduce machining costs while ensuring machining quality and tool wear.

Tool setting: The accuracy of tool setting is also a factor that affects the machining accuracy of aluminum parts. Try to choose a good edge finder, and it would be even better if the machine tool has an automatic tool setter.

Overall, there are many factors that need to be considered in the aluminum CNC machining process, including the stability of the machine tool, the cooling deformation of the workpiece, the three cutting elements, and tool alignment. Only by comprehensively considering and strictly controlling these factors can high-quality aluminum parts be manufactured.
