Advanced Capabilities and Design of the CT-1118CNC CNC Toolroom Lathe #
The CT-1118CNC CNC Toolroom Lathe is engineered to deliver exceptional precision, flexibility, and efficiency for demanding machining environments. Designed as an upgrade from the CTL-618EVS manual lathe, this model integrates robust mechanical construction with advanced CNC control, making it suitable for aerospace, automotive, electronics, and other high-precision industries.
Key Features #
- Guaranteed circular accuracy to 50 millionths of an inch
- Fanuc 0i mate-TF controller (standard), with options for other controllers
- 3 HP motor (5 HP optional) paired with a Yaskawa current vector inverter for enhanced low-end torque
- Spindle mounted on high-precision preloaded angular contact ball bearings
- Precision ballscrews on X and Z axes, with direct AC servo motor coupling to minimize backlash
- Protection guard on Z-axis ballscrew
- Fast lever collet chucking and power collet closer
- Optional gang tooling for increased productivity
- Wide range of accessories to expand versatility
Dual Machining Styles: Center Turning & Gang Turning #
The CT-1118CNC stands out for its ability to switch between traditional center turning and innovative gang turning. The machine retains the durability and classic design of its predecessor while introducing a tool plate system that allows users to remove the compound tool post and install a T-slot gang tool slide. This flexibility enables:
- Easy transition between traditional and gang tooling setups
- Support for both shaft work (with tailstock and lathe center) and high-volume, multi-tool operations
- Compatibility with a comprehensive lineup of CYCLEMATIC gang tool holders
Gang Tooling for Enhanced Productivity #
Gang tooling on the CT-1118CNC simplifies setups for jobs requiring multiple tool changes, making it ideal for higher-volume production of precision parts. The system supports a variety of tool holders and configurations, allowing users to tailor the machine to specific production needs.

Construction Highlights #
- Massive Saddle: Slideways are coated with Turcite-B for wear resistance; cross slideways feature hardened and ground tool steel inserts for smooth, accurate movement.
- Headstock: One-piece enclosed design with high-precision preloaded ball bearing spindle for rigidity and sustained accuracy. The collet seats directly in the spindle, eliminating the need for sleeves or adapters.
- Collet Closer: Fast lever collet closer for quick chucking, with instant tension adjustment. Optionally, an air-operated power collet closer is available for automatic chucking.
- Tailstock: Full bearing support, 95mm travel, dual inch/metric graduations, and automatic tool discharge for MT#2 taper tools.
- Step Chucks: Securely hold work up to 6" in diameter, with closers designed for direct spindle fit and optimal gripping power.
Tooling and Accessories #
A comprehensive selection of spindle tooling, tool holders, and optional equipment is available to further enhance the CT-1118CNC’s capabilities. These include:
- Step chucks and closers (various sizes and depths)
- Threaded positive stops, universal collet stops
- Plug chucks, fixture plates, face plates
- Angle plates, headstock centers, drive plates, driving dogs
- Chuck mounting plates, fine turning chucks, expanding collets
- Hydraulic, pneumatic, and diaphragm chucks
- Single, double, triple, and boring tool holders
- Gang tool blocks (408mm, 96mm, 48mm)
- Drill holders, tap holders, knurling holders, quick-change holders
- Tool setting gages, carriage length indicators, steady and follow rests
- Six-station turret, taper and radius turning attachments, rear tool holder slides, vertical cut-off slides, compound slides, tailstocks, chip and coolant shields, and more

Operational Guidance #
The CT-1118CNC is designed for straightforward installation, operation, and maintenance. Key operational highlights include:
- Leveling and Setup: Use pads under six points, adjust with set screws and pin wrenches, and ensure all points contact the ground.
- Electrical Connections: Machine is shipped fully wired; connect to power source and verify spindle rotation direction.
- Lubrication: Use high-quality lubricants (e.g., Mobil Vactra Oil No.2) for the oil reservoir and monthly grease for ballscrews.
- Collet Closer: Procedures for removal, replacement, and adjustment are provided for both manual and air-operated systems.
- Coolant System: Maintain coolant levels to protect the pump; adjust flow as needed.
- Tailstock and Locks: Tailstock features fine feed, dual graduations, and secure locking mechanisms.
- Control Panel Functions: Includes power, cycle start, feed hold, emergency stop, jog, rapid traverse, spindle controls, coolant controls, and more, with clear indicator lights for machine status and alarms.
