Overview of the Commander III System

The Commander III redefines door and jamb machining flexibility, bridging both residential and

commercial markets. Leveraging our revolutionary KvalCAM® software and Beckhoff hardware,

combined with 6-axis movement, the Commander III provides on-going return for facilities need-

ing to increase capacity and processing capability.

KvalCAM, proprietary door-machinery software, provides auto G-Code generation, complete

machine-line integration, and an intelligent scalable database spanning unlimited KvalCAM

machine lines and even facilities.

Auto G-Code generation enables engineers or operators to easily create template files for a wide

variety of hardware by shape, dimension, and location. Eradicating the need for sophisticated pro-

gramming, customers can increase product offering, inventory turnover, and expand market share

while reducing overhead cost.

Machine-line integration is accomplished by one central control system (KvalCAM) recognizing

each machine’s individual capability within the line and simultaneously assigning tasks to each

piece of equipment from one job or template file. As an end user this simulates a “single machine”

with the output and productivity gains of utilizing multiple machines. Template files can be cre-

ated remotely i.e engineering department, and sent to the machine-line queue for the operator to

select. Additionally, machine can be fed by way of the KvalCAM Barcode Mapper application.

KvalCAM and the Commander III

• Allows effortless creation and processing of new door-hardware templates i.e con-

cealed hinges

• Can process an array of strike and hinge jamb hardware with CNC capability using

front section.

• Mirror functionality allows doors to be processed right or left hand while maintain-

ing sill leading always; never need to rotate for door machining.

• Complete integration with other KvalCAM machines

• -Up to date with Kval’s latest superior technology; continuous updates available as

R&D continues.

*Barcode capable with KvalCAM Barcode Mapper purchase

Standard Features

•Hinge Head – dual spindle routers with counter rotation for clean entry and exit at

hinge corners (eliminates traditional chip-outs), programmable point to point drill

for screw pilot holes, and corner square chisels for door and jamb. Full X, Y and Z

axis programming is combined with precision ball screws and servo motors. Auto

tilt between a three degree door edge and jamb clamped in the square H blocks so

both can be processed simultaneously, as well as auto detect for jamb only and door

only processing without wasted motions.

•Hinge Centers – no collar bars - automatic adjustment with precision encoder sys-

tem combined with a servo motor drive and position lock. The traditional chain and

torque limiter is now a ball screw so an operator can fasten the first hinge after the

hinge head shifts to the second hinge location. A couple of manual adjustments for

H blocks and jamb clamps are still necessary, but a pointer and setup mode reduce

this to under two minutes and eliminates errors.

•Lock Locations – fully automatic positioning for lock locations from the door top,

and up to three locks can processed on one door. Program allows operator to change

between two auto-selections for lock-hole backsets (2-3/8” or 2-3/4”) and Face Plate

widths (1” or 1-1/8”). Zero or three degree bevel can be accommodated with

mechanical adjustment via turret. Up to 5” backset and up to 1-1/4” x 12” face plates

can be manually adjusted. Option FC adds corner squaring and full CNC control of

face plate routing.

•Door Reference Stops – fully automatic positioning of off-feed door stop to match

door length and hinge off-set with a ball screw and servo motor. The infeed stop is

fixed and is the zero reference for all other settings.

•KvalCAM and Beckhoff Control System – integrated components including all Beck-

hoff servo motor and drives. This makes remote support and program updates easier

than ever before. A connection to the internet is required for remote support from

Kval, which can remain physically disconnected except when needed. Software is

pre-installed to monitor all machine functions from our offices in Petaluma when

required.

Additional Features

• Efficient hinge and lock dust take-off connections.

• Auto width adjust to match incoming door widths 18" - 48", or 12" to 48" with

Option ND.

• Door feed system with parallel non-marking belts and heavy duty AC drive for

smooth speed transitions at door reference stops.

• 5 HP lock bore, and 3 HP latch bore with precision Acuflex collets and nuts.

• Auto door clamp.

• Air blow-off to clean the face as the door off-feeds.

• Door hand indicator light to speed processing in a companion 700-C Door Framer.

Reverse Feeds Facing the hinge routing head, the normal direction is

left to right. This option reverses the feed direction to

feed from right to left.

Option

AR

Architectural Door Package Adds a barcode scanner and processing for architec-

tural doors up 2-1/4” thick., which integrates with the

machine’s industrial PC and CNC positioning motors

to completely automate hinge, pattern processing

and lock locations. Door files can be created with the

software which can reference barcode labels, or be

selected from an on screen list for nearly instant

machine set-up. The door files hare identical to those

used in the Kval Face, Edge and DLNC series

machines so one file can be created to be used in

multiple operations. Anti-Static air blow bar to clean

door face is also included in this package.

Option

FC

CNC Lock Face Plate with Chis-

els

Only available in combination with option AR. Adds

CNC control of face plate routing and corner squaring

of face plates. Includes programming and three addi-

tional servo motors, ball screws, drives and four cor-

ner square chisels. Plate size is limited to a maximum

size 1-1/4” x 6”. Adjustment for zero or three degrees

routing is automatic, but chisels mechanically posi-

tioned for three degree plates only

Option

W

Drill Gearbox and Air Motor Adds the ability to also drill holes for lever locks with

geared drill boxes. The drills operate at the same

time as the 2-1/8 bore and do not affect cycle time.

Each drilling pattern requires a different gear box, fit-

ted with a direct coupled air motor which are priced

below. With the direct coupled design, door width

minimum is 18". Changeover from one pattern to

another takes approximately 5 minutes.
