SOUTHWESTERN INDUSTRIES TRL-1440 MANUAL LATHE

Technical Description

The Southwestern Industries TRL-1440 Manual Lathe features a 14-inch swing over the bed and a 40-inch distance between centers, accommodating substantial workpieces. It has a spindle bore diameter of 1.56 inches, allowing for robust bar work. Powered by a 5 HP motor, the lathe achieves spindle speeds up to 2,400 RPM across multiple speed ranges for versatile machining. The machine is equipped with a ProtoTRAK LX2 CNC control system that supports two-axis control, combining manual lathe operation with CNC precision. It includes electronic handwheels and a joystick for intuitive manual positioning, along with programmable features such as circular and linear interpolation, canned cycles, threading, and geometry-based programming for efficient complex part machining. The lathe incorporates precision ground ball screws on the saddle and cross slide, providing high positional accuracy and repeatability. Its construction features a Meehanite cast monolithic base with heavy ribbing for rigidity and vibration dampening. The spindle has a D1-4 cam lock nose with taper MT#5 for tooling compatibility. Additional features include a standard tailstock with manual quill, steady rest provisions, and a work lamp to illuminate the machining area. The lathe supports 5C collet chucking and is suitable for applications requiring high precision with manual or CNC operation, such as prototype, toolroom, and small-batch production machining. Footprint and weight support stable installation in toolrooms or job shops. Overall, the TRL-1440 offers a balance of robust mechanical design and modern CNC capabilities.
