Because I don't know the shape, size, material processing requirements and other important information of your workpiece, I will simply say it according to my personal processing experience for reference:

1, try to use the attached fixture, which is convenient for transportation and can ensure the positioning accuracy when positioning for many times.

2. It is suggested that vertical and horizontal rigid structures should be used for step-by-step transportation instead of belt transportation.

3. It is suggested that loading and unloading should be considered as two stations to realize automation and semi-automation.

There is too little information, maybe I have a little misunderstanding, please forgive me. Thank you.

As if you mean moving in the z direction? That is, there are 7 stations in the horizontal X direction, and each station needs machining after the Z axis moves up vertically? Questions and discussions are welcome.
