1、Require design, process, and programming calculations to be unified

2、Minimize the number of clampings as much as possible, and complete the cnc machining surface after one positioning.

3、Avoid adopting the manual adjustment scheme of occupying the machine

4、The fixture must be open, and its positioning and clamping mechanism must not affect the tooling in cnc processing (such as collision). In such cases, you can use a vise or a base plate to extract the screw.
