5-4. Nail Driving Force
Fig. 2 shows by type of wood and nail, the nailer output energy provided by the supply pressure and the nailing
energy required for driving the nail flush. Air pressure which exceeds the intersecting point between the nailer
output energy and the nailing energy required for driving the nail allows the nail to be fully driven.
For example, when driving a nail of 3.3 mm dia. by 83 mm length (0.131" x 3-1/4") into nine sheets of 12 mm
2
plywood (108 mm thick ) with the Model NR 83AA3, a pressure of about 7.0 bar (7.1 kgf/cm
, 102 psi) allows the
nailer to drive the nail flush with the wood surface. A pressure beyond this value causes the nail head to be driven
below the wood surface. Fig. 2 should be used as reference data because those values vary depending on the
type, moisture content, and grain of wood.
