Advanced Capabilities for Modern Toolrooms #
The CTL-618e toolroom lathe is engineered for high-speed, high-accuracy machining, making it an ideal choice for toolmakers and precision part manufacturers. This model stands out by replacing the traditional threading gearbox with a computer-controlled servo motor directly linked to the leadscrew. This innovation allows users to select the desired thread pitch via a touchscreen display, ensuring precise threads and eliminating the need for specialized gear sets.
Key Features #
- Digital Threading Control: The CTL-618e utilizes a microprocessor-controlled, servo-driven leadscrew, enabling instant selection of thread pitches (both metric and inch) without manual gear changes. Simply input the desired pitch on the LCD touchscreen, and the system synchronizes spindle rotation and Z-axis feed for accurate threading.
- Integrated DRO Functions: Built-in digital readout (DRO) capabilities come standard, with linear scales on X and Z axes from Mitutoyo, providing real-time feedback on spindle speed, feed rate, and tool position.
- High Precision: Guaranteed circular accuracy of 50 millionths of an inch, suitable for super high-precision work on small parts, especially those fitting in 5C collets.
- Noise and Vibration Reduction: The absence of gears in the gearbox significantly reduces operational noise and vibration during threading.
- Rapid Retract Function: Shortens processing time for pitch and module turning.
- Easy Metric/Inch Switching: Effortlessly switch between measurement systems, with accuracy up to three digits after the decimal point.
- Digital Overload Monitoring: Real-time display of electric current for easy overload detection.
Control Panel and Operation #
The CTL-618e features an intuitive LCD touchscreen interface for all major operations:
- Thread Pitch Selection: Choose thread pitch and type (right/left hand) directly on the screen.
- Spindle and Feed Monitoring: Digital display of spindle RPM and tool infeed.
- Memory Functions: Store up to 8 sets of X and Z positions for repeatable operations.
- Automatic Thread Length Control: Ensures precise thread termination, especially for blind holes or shoulders.
- Dynamic Braking: Inverter unit with discharge resistor for rapid spindle stop.
