The South Bend SB1047PF 21x80 Turn-Nado Gearhead Lathe is a professional-grade industrial lathe built for daily use in demanding production environments. Powered by a robust 15 HP motor with 16 spindle speeds ranging from 20 to 1600 RPM, this heavy-duty metal lathe delivers exceptional performance for precision machining operations.
Advanced Gearhead Design for Industrial Applications
Engineered for busy machine shops, this gearhead lathe features quick-change gear levers that provide seamless control over spindle speeds. The integrated spindle clutch allows operators to switch between forward and reverse without shutting down the motor, significantly improving productivity and reducing downtime in production settings.
Precision Digital Readout System
Factory-installed Fagor 2-axis digital readout displays real-time positioning of both the carriage and cross slide, ensuring accurate measurements and repeatable results. This DRO system is essential for precision metalworking and complex machining operations.
Professional-Grade Components
High-quality SKF spindle bearings provide smooth, reliable operation and extended service life. The D1-8 camlock spindle features an MT7 taper with a 3.15-inch bore, accommodating large workpieces. The tailstock includes an MT5 taper with 6.5 inches of quill travel for versatile machining capabilities.
The headstock is equipped with a pressurized oiling system that pre-lubricates bearings and gears before spindle startup, protecting critical components and extending machine life.
Rigid Meehanite Construction
The lathe bed is constructed from hardened Meehanite castings, precision-ground in the traditional three V-way prismatic design. This rigid construction minimizes vibration and maintains accuracy during heavy cutting operations, ensuring consistent results across long production runs.
Comprehensive Threading Capabilities
Machine a wide range of thread types with 38 inch thread pitches from 2 to 72 TPI, 40 metric thread pitches from 0.4 to 14mm, 18 modular threads from 0.3 to 3.5, and 21 diametral threads from 8 to 44. This versatility makes the SB1047PF ideal for diverse manufacturing applications.
Reliable Allen-Bradley Controls
Quality Allen-Bradley electrical components provide dependable control of all powered movements. The attention to detail in electrical design ensures reliable operation and easy troubleshooting when needed.
Complete Package with Chucks
Includes both a 14-inch 4-jaw independent chuck and a 12-inch 3-jaw scroll chuck mounted to D1-8 plate, providing immediate versatility for different workholding requirements.
