Aluminum is the most widely used and widely used metal material in non-ferrous metals, and its application range is still expanding. Today, Xiaobian will introduce to you the process of aluminum CNC machining parts and how to avoid CNC machining deformation.
The aluminum part machining process can separate roughing and finishing. After rough machining, the parts are heat treated to fully release the cutting stress and residual heat, and then finish machining, which will greatly improve the machining quality of aluminum parts.
In layman's terms, the fixture is six points (3+2+1: three-point fixed surface, two-point fixed line, one-point fixed), and machining needs to solve the deformation. There are many reasons for the deformation of common aluminum parts machining, which are related to the material, shape of the part, and production conditions.
Aluminum CNC machining anodized shells often have a high yield and good appearance and texture, but the cost is high, the amount of CNC machining is large, and the CNC machining cycle is long. Typical cost-effective high-quality chassis, such as the Apple series.
During the cutting process, the thin wall is easily deformed by the cutting force, resulting in an ellipse or a "waist-shaped" phenomenon with a small middle and large ends. In addition, due to the poor heat dissipation during CNC machining, the thin-walled sleeve is easily thermally deformed, and it is not easy to ensure the CNC machining quality of the parts.
What else do you know about CNC machining? The 29 pieces of CNC machining knowledge compiled by the seniors, let's not say much, let's take a look.
CNC machining has grown into one of the most critical manufacturing processes used in workshops around the world. Adding computer control to a previously manual process enables a leap forward in the accuracy and precision of CNC machined parts.
