5-3. Nail Driving Force
Figure 4 shows the energy required to drive a nail flush and the output energy of the NV 50AF3 nailer.
When the supplied pressure is adjusted so that the output energy of the nailer equals the energy required for
driving a nail, the nail can be completely driven.
For example, in driving wire-collated nails of 2.1 mm dia. x 50 mm length (0.080" dia. x 2" length) into Hemlock
below a 12 mm plywood sheet with the Model NV 50AF3, a force of about 5.3 bar (5.6 kgf/cm
2
, 79.8 psi) is
required to drive the nail flush with the surface of the plywood. If the nail is driven with a force more than 5.5 bar
(5.6 kgf/cm
2
, 79.8 psi), the nail head will be sunk below the wood surface. Please use Fig. 4 as a rough guide
only, because figures vary according to the workpiece materials, moisture content, and grain of the wood.
