Once the barrel stubs were pressed out of the trunnions
, the remaining sheet metal receiver needed removed from the trunnions
Installation of the trunnions

press also has a table capable of tilting 45[degrees] forward and 90[degrees] side-to-side, by loosening the knobs under the table while the table itself rotates on two trunnions
Horizontal index trunnions
provide access to three sides of the workpiece, allowing complete machining in one loading and, consequentially, driving significant production increases on vertical machining centers.
To begin, front and rear trunnions
need to be installed in the new receiver.
Multi-axis, swiveling trunnions
reduce changeover times and D- and A-axes bring parts into position.
Automatic work changers feature two horizontal fixture trunnions
that are mounted to a main trunnion
It has both an aluminum stock adapter and aluminum tube that has an integral adapter for mounting to AKMs with fixed stock rear trunnions
. Since it is foreign-made, ensure the foreign parts count does not go over 10 by having sufficient American-made parts elsewhere.
