What is Digital Threading Control?
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.

ADJUSTMENT PROCESS FOR LIFTING MACHINE
- Put pads C (Figure B) under each of six points.
- Loose set screw A (Figure B)
- Insert a pin wrench into the hole B. raise or lower by turning (C.W. or C.C.W)
- Tighten set screw A (Figure B) to lock.
- Be sure every point is touching the ground to support the machine.
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.
A.) INSPECTION AND CLEANING OF MACHINE
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
B.) FOUNDATION, INSTALLATION, AND LEVELING
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.

P.) CARRIAGE CLUTCHES
- The carriage clutches are made of a friction type material, designed to slip when slide or carriage engages a feed stop. The clutches are a spring-loaded arrangement and can not be adjusted for more pulling power. If clutch slips under a cut, it is a sign of improper tool grinding, dull tool or excessive feed. The friction clutches have sufficient power to handle all work.
- When the machine contacts a feed "stop", it is intended for the clutch to slip, To operate clutches as shown in (Figure 29), raise handle "H" (Figure 29) approx. 20 degress above horizontal, the clutch will engage, Push down the handle "H" (Figure 29), the clutch will release. When the carriage lead screw is engaged for threading the carriage feed clutch is mechanically interlocked (can not be engaged). This is to prevent machine damage. Adjust clutches as shown in (Figure 29).
Q.) CROSS SLIDE INDICATING RING
Dual dials with inch and metric hand wheel dial. Each graduation of the Indicating Ring "C" (Figure 30) is 0.02mm (0.001") on the diameter. It is provided for operator's convenience. The Indicating Ring is spring loaded, so a lock screw is not needed. To use it, just turn the Indicating Ring to required location by hand. Cross Slide operation of free and adjustment of clutches are identical with the operation and adjustment of carriage clutches. If CTL-618e TOOLROOM LATHE needs to be used with the taper turning attachment, loosen the screw "S" (Figure 30) with a spanner wrench.
R.) QUICK-ACTING TOOL POST COMPOUND SLIDE ASSEMBLY

It is
powered by AC motor "M" (Figure 32).
- The power feed can be operated only when the machine is running. Start the power feed by turning Cam Switch "S" (Figure 33).
- The Cam Switch "S" (Figure 33) controls the direction of the power feed.
- The carriage Feed Control "N" (Figure 33) controls the rate of feed. When Cam Switch "S" (Figure 33) is placed in "RIGHT" position, the carriage will feed toward the right, the cross slide will feed away from the operator.
- When Cam Switch "S" (Figure 33) is placed in "LEFT" position, the carriage will feed toward the left, the cross slide will feed toward operator.
- Turn Cam Switch "S" (Figure 33) to "STOP" position, power feed motor is turned off.
- The rate of the carriage feed should be pre-selected to suit each particular job, which depend on material, diameter, type of cut, and tooling used.
- The numbers on the carriage feed control panel, do not represent either thousandths per revolution or inches per minute. So the operator must test sample pieces for determining the spindle speed and rate of feed which can best suit to the requested surface finish and production rate, then record the proper settings after testing.
NOTE：
WHEN STARTING INTO PRODUCTION. AN OPERATOR CAN SET THE FEED CONTROL
"N" TO THE RECORDED REFERENCE SETTING, THEN THE SAME TESTED RESULTS
WILL BE OBTAINED.
T.) COOLANT FACILITIES
The coolant pump is controlled by Switch "C" (Figure 34). Turn Switch "C" (Figure 34) to "ON" position, the pump will run continuously, turn to "AUTO" position, the pump will run only when the machine is running. If pump switch is set at "OFF" position, the coolant pump is off. Pump should be cleaned periodically, depending on the type of material being machined.
U.) TAILSTOCK
The tailstock is mounted on preloaded ball bearings and can support any load to the spindle. It is provided with a fine "feed" for accurate work. The spindle of the tailstock is graduated in eighths of an inch, and 1 mm and has a travel of 95mm (3-3/4") The hand wheel is dual dial Inch and Metric. Graduations are 0.02mm (0.001"). It is built for the operator's convenience of operation just turn the dial ring "D" (Figure 35) to the required location. It is unnecessary to tighten the dial rings. They are spring loaded, so a lock screw is not needed. Sliding cover cage exposes only the dial in use.

High Speed/high Accurancy Toolroom Lathe With Digital Threading Control Replaces Traditional Threading Gearbox
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.
The First Choice Of Toolmakers!
- 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.

What is Digital Threading Control?
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.
