Operation manual Optional
This lathe doesn't use threading gearbox, instead
computer-controlled servo motor is directly linked
to the leadscrew. Just use your finger to select
desired thread pitch on the touchscreen display,the
threads come out absolutely precise and you
totally eliminate problems with specialized
threads.The disply also shows spindle speed,
cutting feed rate and DRO functions.
Good for pitch and module turning processing without any gears in gearbox. Easy exchange of inch and
metric system, accuracy goes up to three degits after decirnal point.

Digtal data shows R.P.M. of spindle and tool infeed to let operator arrange best possible turning process
combination.
Digtal data showing electric current for easy checking overload turning.
Rapid retract function is available for shortened pitch module turning processing time.
The lead screw is driven directly by servo- motor. Through operation of interface, a spindle decoder is
used to transfer the motion of lead screw to rectilinear one. The L.C.D touch pad showing the data is
applied to control.
Rapidly returning to the origin is executed according to the principle of temporarily coming off the
tracking mode.
Feeding rate per minute of auto feed is calculated with MODBUS communication protocol interior
message data of the converter, so that user s' cutting precision is available much easily and greatly.

CTL-618e toolroom lathe with Digital Threading Control replaces traditional threading gearbox with
microprocessor-controlled, servo-driven leadscrew. In the past, when a machinst is faced with a workpiece
that calls for thread pitch not supported on a conventional lathe, he has to locate and order a custom gear
set and take the time to swap out the gears in the gearbox. This is not economically justifiable unless the
volume is large enough. CTL-618e toolroom lathe's design eliminates this time-consuming workaround.
With the new digital threading system, the user's wishes with it comes to threading can be easily and
immediately realized.
Simply type in the desired thread pitch on the numeric keypad on the touch screen LCD control panel and
then start the threading cycle as on other conventional lathes. CTL-618e's system would control and
synchronize main spindle rotation and Z-axis feed rate to produce precise threading cycle for the given TPI
or mm thread pitch.
Besides being able to cut thread pitches not previously available on manual lathes, noise and vibration
during threading are also significantly reduced, because there are actually no more gears in the gearbox.
Since CTL-618e already has custom IC and a LCD panel to enable threading control, the next logical step
is to integrate DRO functions into it for an all-in-one versatile machine. And CTL-618e has in-fact done
that. DRO capabilities are built-in and come standard with no extra charge. CTL-618e features linear
scales on X and Z-axis from Mitutoyo.
For people experienced with the super high precision and immediacy of CYCLEMATIC's toolroom lathes,
the CTL-618e adds another dimension of capabilities. It builds on the same foundation as 618EVS
toolroom lathe. They are all ideal for super high precision lathe work on small parts (usually those that fit in
5C collets). The guaranteed circular accuracy is 50 millionth of an inch.

Figure 1 - Lifting machine
Lifting machine, arrange rope or cable as shown in figure 1, and check to see if the correct balance has been
obtained. Then insert pads of soft cloth between the edges of the rope and machine. The net weight of this
machine is approx 1100 kgs (2420 lbs). So the rope or cable must be rated at 3000 lbs capacity.
TOP
An inspection should be made after arrival of the machine in your plant. Look for possible damage caused by
shock or vibration during transportation, also check for any missing parts, standard tools or other equipment.
In shipment, all exposed surfaces of the machine are coated with a antirust liquid. Before moving carriage
and cross-slide, lead screw, tailstock…etc, these surfaces should be thoroughly cleaned to remove all
antirust liquid use a soft brush and solvent. This is very important because it can prevent any dirt or grit which
may have accumulated on the antirust liquid from working under the sliding members and causing undue
wear.

※CAUTION：
DO NOT USE COMPRESSED AIR TO CLEAN, WHICH WILL REDUCE THE MACHINES LIFE

A fairly flat foundation and proper installation will provide the machine long-term high accuracy, so
supplying a good solid foundation of proper thickness is important. (Generally, a thickness of 300mm (12")
is considered to be enough.) The machine has six adjustable feet on the corners of the pedestal base, used
for leveling the machine. Place the pads under the feet of pedestal. To adjust, loosen the set screw and
raise or lower the foot with a pin wrench so that all six feet rest firmly on the floor. When the adjustment is
done, tighten set screws.
