CTL-618e Manual Lathe

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