clamp, and the cutter from damaging the opposite
key clamp. To adjust the safety stop screw, loosen
the Lock Nut and adjust the stop screw in or out, to
establish a 0.2 mm (.0078”) clearance between the
tracer point and the pattern key vise. Tighten the
Lock Nut to lock in this adjustment.
Figure 6, shows a right quarter view of the key
machine. The Speed machine uses a large diameter
HSS (High Speed Steel) cutter. The 1650-rpm motor
is reduced to produce a cuter speed of 1404-rpm.
This is an appropriate speed for brass key blanks.
The large diameter TiN coated HSS milling cutter
should afford the locksmith a long cutter life. The
cutter shaft is mounted in dual ball bearings, which
will give the machine good accuracy and long life,
even in heavy service.
The Chip Tray, in the base of the machine, pulls
out for easy cleaning.
The Power Indicator light on top of the motor
indicates that the Magnetic Power Switch is
activated. The Power Socket accepts a removable
Figure 7, details the Electrical Power Socket.
The Power Socket incorporates a double fuse block,
which protects the motor. Pull out the fuse carrier,
and hinge down the cover, to expose two 120 Volt, 8
Amp fast blow fuses.
The Speed machine comes with a set of “field
service” tools and accessories, as you see in Figure
8. Two “line fuses” are furnished. Always use the
same type and rating fuses, to protect the machine.
Calibration Keys are provided for adjustment of the
flip-up shoulder gauge stops. They are accurate and
should be used to check and adjust the shoulder
gauges, when necessary.
A cutter Release Pin and 19 mm Spanner are
provided, for changing the cutter. The Release pin
fits through a hole in the cutter shaft, to prevent the
shaft from rotating while loosening or tightening
the cutter retaining nut. Remember, the cutter nut is
“Left Handed.” Left rotation tightens. Right rotation
loosens. 2. 5 mm and 3 mm Metric Allen Wrenches
are provided in the tool kit, and will fit all field
serviceable socket head fasteners.
1.2 mm and 1.7 mm Shim Pins are furnished,
to allow clamping of irregular keyways. Gauge
Bars allow keys to be tip gauged, gauged by a rear
shoulder or gauged by a reduced-tip shoulder (as
Best or Falcon SFIC keys).
