A dedicated fixture for axle housings, differential carriers, gearbox casings and similar long castings, where the part is heavy, the wall is thin in places, and the machined faces must stay coaxial to each other after clamping.
The design usually combines a 3-2-1 location on the machined pads with adjustable supports under the unsupported span, so the casting is held against its own weight rather than straightened by the clamps.

How it is built
Clamping that does not straighten the part
A long casting clamped at both ends bows in the middle. Supports are set from a measured free-state profile, so the part is held in the shape it had before clamping, and the bores stay coaxial.
Real photos before you commit
For housing work we send photographs of the assembled fixture with your part type, plus the CMM report. It is a large purchase, and drawings alone are not enough.
Handling designed in
Hoist points, a lifting plan and a floor frame mean the fixture is moved safely by the same crane that moves the part.
