Republic Lagun Machine Tool ATV-618-ET With Electronic Threading (ET) Ultra Precision Lathe

OUTSTANDING FEATURES

    • Electronic Variable Speed drive system. 3 HP Yaskawa inverter; 50 to 4,000 RPM
    • Complete 3/60/220 volt electrics with 110 volt controls and thermal overload protection
    • Flood coolant pump and nozzle
    • Standard 5C collet closer (manual)
    • Inch/metric dual dials
    • Tailstock MT # 2
    • Welded steel pedestal/cabinet
    • Work light

     

     

Includes standard equipment as described above.

 

  • Microprocessor Controlled Electronic Threading completely eliminates mechanical gearbox and gear changes. The spindle rotation is synchronized with servo-driven lead screws and Z axis feed rate to provide threading cycle for the selected inch or metric thread desired. This arrangement allows a grander range of inch threads from 4 to 120 TPI and metric threads from 0.2 to 10 mm. This provides a higher degree of accuracy than is possible through conventional gearboxes found in the market today.
