Overview of the Commander III System

The Commander III incorporates CNC movements on six axes and a Beckhoff touch screen to

automate setup for up to 12 different door specifications. Custom specifications can also be

entered directly at the touch screen for special doors.

An optional package for architectural door processing is also available including a PC interface

and Kval software that allows unlimited predefined set-ups for doors up to 2-1/4” thick and bar-

code scanner for program selection.

Standard features include:

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 cor-

ner square chisels for door and jamb. Full X, Y and Z axis programming is combined with preci-

sion 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 system combined

with a servo motor drive and position lock. The traditional chain and torque limiter are retained 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 selection for lock hole backsets of 2-3/8” or 2-3/4” and

either 1” or 1-1/8” face plate width at zero or three degrees (two auto selections). 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 in-feed stop is fixed and is the zero reference

for all other settings.

Additional features include:

• Efficient hinge and lock dust take-off connections

• Auto width adjust to match incoming door

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

smooth speed transitions at door reference stops.

• 5HP lock bore, and 3 HP latch bore with precision Accuflex 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 700C door framer.

Operators Interface:

The operator interface for the Commander III is simple and requires very minimal training to cre-

ate door specifications. Dimensions are entered at the amply sized 19” Beckhoff touch screen for

hinge layout from the door top, hinge reveal, hinge size, ¼”radius, 5/8”radis or square corners,

Overview of the Commander III System

1-3

KVAL Commander III Service Manual

hinge bevel (0 or 3), lock locations, lock backset (2-3/8” or 2-3/4”) and door length. Multiple pat-

terns for screw pilot hole can be selected from a drop down list. Each specification can be

assigned to one of the twelve preset buttons, or run as a special. Left or right hand processing is

via selector switch. A key switch is provided to lock out access to specification changes.

About the Software:

The backbone of the Commander III is a Beckhoff control system with integrated components

including all Beckhoff 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 mon-

itor all machine functions from our offices in Petaluma when required.

Table of Options

Option Title Description

Option

AH

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.

Safety Terminology of Labels

In addition to the nameplate, KVAL machines may have other warning labels or decals that pro-

vide safety information to operators. Safety labels should be clearly visible to the operator and

must be replaced if missing, damaged, or illegible.

There are three types of warning labels or decals:

• DANGER means if the danger is not avoided, it will cause death or serious injury.

• WARNING means if the warning is not heeded, it can cause death or serious

injury.

• CAUTION means if the precaution is not taken, it may cause minor or moderate

injury.

Safety Guidelines

In addition to the caution and warning labels affixed to this machine, follow the guidelines below

to help ensure the safety of equipment and personnel.

This machine is a powerful electro-mechanical motion control

system. You should test your motion system for safety under

all potential conditions. Failure to do so can result in dam-

age to equipment and/or serious injury to personnel.

Ensure that all employees who operate this machine

are aware of and adhere to all safety precautions

posted on the machine and are trained to operate this

machine in a safe manner.
