This Tsudakoma combination table for high production engine block manufacturing
is designed especially to be encapsulated in automotive flexible transfer lines
or built into high production automotive parts machines. The table features an
oversize driving mechanism and hydraulic tailstock support capable of handling
heavy eccentric loads along with a powerful dual disk hydraulic clamping system
on both the driving and outboard side of the cradle. A 10 port rotary joint system
delivers hydraulics to the fixture plate for clamping. The table is also designed
for easy maintenance and can be equipped with ultra precision feedback devices.
