As an important link in CNC machining of aluminum frame, some novices only know a little about CNC machining. What Xiaobian wants to say is that the basic principle of clamping is horizontal length and vertical short. Next, senior operators will explain to you what are the lower clamping methods?
Splint clamping is specifically used to code the splint on the CNC processing table, and the workpiece is locked on the splint with screws. It is suitable for clamping with insufficient height, and can also be applied to workpieces with large processing force or general medium and large workpieces, and the effect will be good.
The clamping of cutting tools refers to that the diameter is more than 10 mm, and the clamping length is not less than 30 mm; when the diameter is less than 10 mm, the clamping length should not be less than 20 mm. The clamping of the tool should be firm to prevent the phenomenon of hitting the tool or directly inserting into the workpiece.

The clamping height of vise should not be less than 10 mm. It is necessary to specify the clamping height and processing height when processing workpieces. The processing height should be about 5mm higher than the vise plane to ensure the firmness, so as not to damage the vice. The clamping height is related to the size of the workpiece. When the workpiece is large, the clamping height increases accordingly.
Code iron clamping is mainly used when the workpiece is large and the clamping height is not enough, and it is not allowed to lock the wire at the bottom. This kind of clamping needs to be clamped twice. First, the four corners should be coded, and then the other parts should be processed, and then the four sides should be coded to process the four corners. During the second clamping, do not let the workpiece loose, code first and then loosen. You can also code both sides and process the other side.
From the above several clamping methods, it is not difficult to find that the different processing methods are different. In the CNC machining process of aluminum frame, we need to select according to the specific workpiece.
