Introducing the CN6140B, CN6240B, CN6150B, and CN6250B series lathes



In the field of metalworking, classic engine lathes such as the CN6140B, CN6240B, CN6150B, and CN6250B stand out for their reliable performance and practical design. These models are designed to provide stable metalworking capabilities for the workshop, featuring a refined machine-green body and metallic control surfaces, creating a timeless industrial aesthetic. They emphasize precision, rigidity, and everyday usability, suitable for a variety of general turning, facing, threading, and maintenance tasks. Whether in a small workshop or large-scale production, these lathes can flexibly handle different workpiece requirements, helping users complete tasks efficiently.

Specifications and Application Advantages of CN6140B



As the core model in the series, the CN6140B boasts a 400mm overhead traverse diameter, confidently handling a wide range of workpiece sizes. This model offers various machining length options, including 1000mm, 1500mm, 2000mm, and 3000mm, allowing users to select the appropriate configuration based on production scale and workshop layout. This makes the CN6140B suitable for a variety of scenarios, from compact operation to long-spindle machining. The robust headstock structure and intuitive control layout, including mechanical selectors for spindle and feed operations, facilitate daily use. The large carriage assembly, equipped with large handwheels and a stable transverse slide, supports precise manual adjustments and smooth cutting control. The generously designed tailstock, with convenient handwheels for supporting centers, drills, or extension components, further enhances the machine's adaptability. Integrated work lights improve visibility in the cutting area, ensuring more precise and reliable operation. These features make the CN6140B ideal for manufacturing workshops, maintenance departments, and technical training facilities.

The CN6240B features a durable design and ease of operation.



Similar to the CN6140B, the CN6240B maintains a classic design style but is optimized for specific needs. It also features a 400mm upper bed swing diameter and supports the same length options, ensuring consistency and interchangeability across the product line. The CN6240B's long, straight, and robust bed emphasizes stability during machining, making it particularly suitable for continuous operation with long workpieces. The control panel is front-mounted for easy operator access, minimizing unnecessary movement and improving workflow efficiency. The feed rod and lead screw extend along the front of the machine, supporting accurate longitudinal feed and threading performance. The tool holder is practically positioned for easy tool changes and stable clamping. The industrial elegance of this model lies in its simple geometry, robust castings, and polished handwheels, embodying a perfect balance between mechanical reliability and functional convenience. For users requiring durable equipment, the CN6240B offers enduring performance and a professional appearance.

Extended Functions of CN6150B and CN6250B



The CN6150B and CN6250B, as extended models in the series, further enhance versatility. The CN6150B focuses on finer control, suitable for complex turning tasks such as internal boring, taper turning, and thread cutting. Its heavy-duty bed provides rigid support, and smooth carriage movement ensures consistent accuracy. Similarly, the CN6250B matches the former in length options, suitable for machining extended workpieces, and integrates modern elements such as work lights to improve visibility and operating comfort. The tailstock and compound carriage design of these models allows for precise tool positioning, supporting multiple operations including external turning and internal machining. Overall, the CN6150B and CN6250B inherit the series' robust architecture while optimizing ergonomic controls, helping users achieve efficient production in a variety of metalworking environments.

The value of the product series in practical applications



These lathe series—CN6140B, CN6240B, CN6150B, and CN6250B—not only boast a professional and durable appearance but also represent the enduring style of precision manufacturing. Suitable for machine shops, maintenance departments, and technical training centers, they offer a combination of classic manual control and broad application capabilities. Whether for small batch operations or general maintenance, these machines meet your needs, ensuring stability and precision. If you work in the metalworking industry, choosing these models will provide a reliable return on investment.
