Overview of the 990-HB Door Hanging System
The KVAL Model 990-HB door pre-hanging system combines very high quality hardware detail-
ing, with high speed productivity. Unique features include:
• Computer controlled ball screw movements for all routers and chisels, complete
with square hinges and lock face plates.
• The ability to process doors as narrow as 12.0'' with hinge pockets only.
• Pushbutton adjust for either 6'8'' or 7'0" doors.
Functions include:
• Hinge and faceplate routing and boring for lock and bolt.
• All routing and chisel movements are controlled with Beckhoff AC servo motors
and motor controllers combined with precision ball rail and ball screws. Motions are
extremely accurate and smooth to assure high quality detailing of either square or
radius pockets.
• The lock face plate router and each hinge routing head is independent with X,Y, Z
servo motors.
In total, there are nine axes for the hinge routers/chisels/predrill, three additional axes for the face
plate router/chisels and a final axis for lock positioning. In addition, an AC servo motor is used to
drive the feed belts to accurately position the door without belt scuffing.
After the automatic routing and boring cycle, three hinges are simultaneously fastened with three
independent six shooter screw-driving heads. Quick screw change hoppers provide the ability to
efficiently change screw color on demand to match orders. The screw hoppers are mounted for
easy access from ground level for screw color changes, or to add more screws.
The 990-HB also includes automatic door width adjustment to accommodate mixed stacks (12.0''
– 42.0'' doors) and automatic door positioning with an AC servo driven feed belt system.
Door widths between 12.0''-16.0'' can be processed for hinges, but lock boring is limited to doors
with a minimum width of 18.0''.
Push button adjust for 6'8'' or 7'0''doors, with fixed hinge centers between the two door lengths.
The lock location is programmable with servo driven ball screw.
