KVAL 990-F4 Service Manual

1-2

Overview of the 990-F4

The 990-F4 is designed for both interior and exterior

doors and jambs. It will accommodate 1-3/8" and 1-3/

4" doors with a minimum width of 18" and a maximum

width of 48" and door lengths of 6' 8" or 8' 0". The

machining sequence includes automatic routing of

either 3-1/2" or 4" hinge pockets (see note below) on

both the door and jamb and complete cylindrical lock

machining, including faceplate. Cycle time is approxi-

mately 10 seconds. Hinges may be attached manually

or with the optional Six-Shooter or Eight-Shooter

Screw Gun while the door and jamb remain clamped in

position. Door-to-door productivity, including hinge

mounting, is typically 35-55 seconds. However, this

varies depending on the operator and material flow. Automatic width-adjust is included in the

base price.

The lock machining assembly will be positioned with a servo driven shaft screw. This is con-

trolled by a touch screen, and will allow settings for standard lock and dead bolt locations based

on the lock bore location. A third dead bolt bore may easily be added by entering the position on

the touch screen. In addition, custom lock bore and dead bolt locations may be entered on the

touch screen for any position within the travel of the servo driven screw.

The servo driven system will also automatically position the lock boring assembly when the door

hand is changed.

This machine is equipped with a solid state touch screen that replaces many of the mechanical

switches for the machine functions. The touch screen also includes the capability to view the sta-

tus of the various photo eyes and switches for quick diagnosis when needed, without having to

open the electrical panel or for the operator to leave his work station. The Touch Screen logic also

includes management functions such as Daily and Lifetime Totals.

KVAL's 990-F4 is the perfect marriage of our high-speed pre-hanging line with the additional flex-

ibility to machine 6'8" doors for three hinges and 8'0" doors with three hinges. Changeover from

one door height to the other takes only a couple of minutes and requires no tools. For even greater

flexibility, the 990-F4 can be equipped with the optional Six-Shooter to install 3-1/2" x 3-1/2"

hinges, as well as the optional Eight-Shooter for attaching 4" x 4" hinges. This machine is gener-

ally used in conjunction with the Handler Door Feeder, 700-C Assembly Machine with 8'0" door

capability, and the 960-3 Strike Jamb Router.
