company news about Mechanical processing of aluminum parts, height 310.6mm

I saw that the height of the aluminum part is 310.6mm. I thought the factory's machining center couldn't manufacture it, so we went to the machine for actual measurement. Please see the picture. The 850 model 5-axis machining center can manufacture parts with a height (z bearing) of 400mm, but we need to find a new way to fix the aluminum block.
The 4-axis machining center of V-1165 model can be manufactured completely.
