Key Advantages
Ledpsvzzffofx Adiohd

Versatile applications – external and internal cylindrical and conical turning, drilling, reaming, polishing, and threading across a wide range of sizes.

Powerful 5.5 kW motor – smooth operation even under heavy loads.

Large spindle bore ø82 mm – allows machining of long and heavy shafts.

2-axis digital readout with optical scales – improves accuracy and operator comfort.

Removable bridge – accommodates workpieces up to ø690 mm × 240 mm.

Rigid cast-iron construction – 300 mm wide hardened and ground bed minimizes vibrations and ensures long service life.

Construction and Technology

The lathe’s foundation is a massive, precisely machined cast-iron bed ensuring maximum stability. The spindle, equipped with a D1-8 spindle nose and supported by reinforced bearings, provides high rigidity and smooth operation at speeds ranging from 25 to 2000 rpm. Hardened and ground gears in the spindle drive offer durability and quiet operation even under continuous use.

Precision and Performance

2-axis digital readout (X & Z) – precise tool positioning with repeatable results.

Joystick for rapid traverse – simplifies cross-slide and top-slide movements, reducing setup and finishing times.

Thread dial indicator – easy thread engagement without manual calculation of turns.
