Overview of the MLX Multi-Point Lock Router

The MLX is a computer controlled machine designed to rout the edge and face of a door for most types of

multi-point lock systems as well as standard cylinder locks, strike plates and simple top and bot-

tom flush bolts. The counter rotating spindles also make it possible to rout through the door edge

or an attached astragle without tear-out. Standard G code programming is used to create template

programs that can be selected directly at the touch screen.

Two counter rotating horizontal spindles rout slots for connecting rods as well as pockets for

latches. Afterwards a vertical router/drill plunges through the door stile to machine for the lock

trim holes larger than 10mm (0.397"). Servo motors are used to move the cutting head horizon-

tally (X axis) vertically (Y axis), and depth of cut (Z axis) on the edge of the door. For the lock

face machining the location and shapes are also computer controlled. The feed table will use non-

marking plastic rolls that will allow the door to be rolled into and out of the machine.

Options Available

At the end of this chapter, there is a safety sign-off sheet. It lists personnel and machine safety cri-

teria to understand before operating the machine. It is highly recommended that personnel operat-

ing, working on a machine meet the criteria listed in this sheet. It is recommended the sheet be

signed and kept for records. See “Safety Sign-Off Sheet” on page 1-20.

Safety Terminology of Labels

In addition to the nameplate, Kval machines may have other warning labels or decals that provide

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.
