What are the positioning standards for CNC machining of aluminum housings?

As we all know, the conductivity of aluminum shell is very good, second only to silver, copper and gold. Therefore, many industrial shells will choose various aluminum shells. The quality of aluminum shell is often related to the processing technology. So what is the positioning standard for aluminum shell CNC processing? Next, Hongfeng Xiaohuang will give you a detailed introduction.

Positioning standard for aluminum shell CNC processing:

1. Design standard: The design standard is the standard used in the design of aluminum parts.

2. Comparison benchmark: If the position accuracy between the two processing surfaces on the workpiece is high, the method of standard repeated processing of the two processing surfaces can be adopted.

3. Multi-reference positioning: In the case of cross positioning, the change of positioning standards can be prevented by designing fixtures and multi-reference positioning. At the same time, the processing quality of the previous process can be checked to prevent processing problems caused by defects in the previous process.

4. Standard stacking: When the positioning of aluminum parts in the aluminum shell CNC machining center is basically inconsistent with the design standard, do a good job of assembly drawing analysis, determine the design function of the aluminum part design standard, and strictly define the accuracy tolerance range between the positioning standard and the design standard through the calculation of the dimension chain to ensure the processing accuracy.
