Fluid Advanced Work Supports; Air Spring" Work Supports - Enerpac WFL 221 Manuel D'instructions

2. Place the workpiece into the fixture and above the work supports. The plunger
should be at the approximate middle of its stroke when contacting the workpiece.
If the weight of the workpiece does not push the plunger down to the proper height,
repeat step 1 and adjust the contact force appropriately.
3. Activate hydraulic pressure to lock the work support plunger into position. The
position of the plunger will be maintained until hydraulic pressure is released.
4. Clamp the workpiece into position to facilitate machining operations.
5. When machining is complete, release hydraulic pressure from clamping cylinders
first, then release hydraulic pressure from work supports.
6. Remove the workpiece from the fixture.

Fluid Advanced Work Supports

1. When no hydraulic pressure is applied, the plunger will be in the retract position.
Place the workpiece into the fixture and above the work supports. The plunger
should be at the approximate middle of its stroke when contacting the workpiece.
2. Activate hydraulic pressure to advance the work support plunger into position.
When hydraulic pressure is applied, a piston pushes against an internal spring that
advances the plunger to the workpiece. As hydraulic pressure increases, the
compression sleeve grips and locks the plunger at the point of contact. The position
of the plunger will be maintained until hydraulic pressure is released.
3. Clamp the workpiece into position to facilitate machining operations.
4. When machining is complete, release hydraulic pressure from clamping cylinders
first, then release hydraulic pressure from work supports.
5. Remove the workpiece from the fixture.

"Air Spring" Work Supports

1. Set the air regulator to the correct air pressure. The correct pressure will vary
depending on the size of the work support and the weight of the workpiece.
2. When no air pressure is applied, the plunger will be in the retract position. Place the
workpiece into the fixture and above the work supports.
3. Shift the handle of the air valve to activate air pressure and advance the work
support plunger into position. The plunger should be at the approximate middle of
its stroke when contacting the workpiece. If the weight of the workpiece does not
push the plunger down to the correct position, repeat step 1 and adjust the air
pressure appropriately
