SOUTHWESTERN INDUSTRIES TRL-1745P MANUAL LATHES

Technical Description

The Southwestern Industries TRL-1745P is a precision manual lathe engineered to maximize the interplay between manual and CNC machining operations, functioning as an advanced digital readout system for manual work. This machine features a robust 17-inch swing capacity with 45 inches between centers, accommodating mid-sized workpieces for diverse turning applications. The spindle bore measures 1.5 inches, providing adequate clearance for standard tooling and workholding accessories. Powered by a 15 HP motor, the lathe delivers the torque necessary for efficient material removal across various materials and feed rates. The spindle operates at speeds up to 2,200 RPM, enabling optimal cutting velocities for precision turning operations. The machine is equipped with the ProtoTRAK LX2 conversational CNC control system, which combines user-friendly programming with flexible manual capabilities. This control system features fixed spindle speed ranges and allows operators to program parts using intuitive conversational dialogue rather than complex G-code programming. The TRL-1745P integrates manual handwheel operation with CNC automation, making it suitable for job shops requiring flexibility in production workflows. The machine accepts standard D1-series spindle nose adapters and supports multiple tooling configurations, including BXA quick-change toolpost setups. The combination of manual versatility and CNC precision control makes this lathe ideal for prototype development, low-to-medium volume production runs, and educational applications where operator skill and machine adaptability are valued.
