HOLDING CAPACITY

nnnn

The holding capacity listed for each

nnnn

clamp refers to the maximum exter-

nnnn

nal force that the clamp can safely

nnnn

resist in its locked position without

nnnn

incurring any permanent deforma-

nnnn

tion. For hold down clamps, holding

nnnn

capacity is measured with the spindle

nnnn

as close as possible to the handle, and

nnnn

will be less at the end of the clamp-

nnnn

ing arm.

nnnn

CLAMPING FORCE

nnnn

Clamping force, the amount of force

nnnn

actually applied to the workpiece

nnnn

by closing and locking the clamp, is

nnnn

generally less than the stated holding

nnnn

capacity. This allows the clamp to

nnnn

have ample capacity to resist exter-

nnnn

nal machining forces. Actual clamp-

nnnn

ing force depends on many factors

nnnn

including: spindle position, proper

nnnn

spindle height adjustment, type of

nnnn

spindle used, workpiece material, and

nnnn

the clamp's mechanical advantage. In

nnnn

most cases roughly 1/2 of the stated

nnnn

holding capacity can be applied by

nnnn

hand with medium effort.
