What to pay attention to when CNC turning aluminum 7075?
- Cooling and lubrication: 7075 aluminum alloy is prone to built-up edge during turning. Good cooling and lubrication can reduce cutting temperature, reduce the generation of built-up edge, and improve the quality of machining surface. Special aluminum alloy cutting fluid can be selected, which has good lubrication, cooling and cleaning properties. During the machining process, ensure that the cutting fluid can be fully sprayed into the cutting area.
- Prevent deformation: Since the elastic modulus of 7075 aluminum alloy is relatively small, it is easy to deform during turning. In order to reduce deformation, suitable fixtures can be used to clamp the parts, such as soft jaw chucks or slit sleeves, to increase the uniformity of clamping force. At the same time, appropriate aging treatment can be arranged between rough turning and fine turning to eliminate machining stress.
- Tool wear monitoring: During the turning process, pay close attention to the wear of the tool and replace the tool in time. After the tool is worn, it will lead to problems such as increased cutting force, decreased machining surface quality and dimensional accuracy. The degree of tool wear can be judged by observing the shape, color and sound of the chips, and measuring the dimensional accuracy and surface roughness of the parts.
