The lathe model 1682A is designed for roughing and finishing work on
cast iron or steel parts weighing up to 170 tons.
Production year 60’ and complete retrofited in 2011
The largest workpiece dimension above the support is 2500 mm.
Parts can be machined using both high-speed steel and carbide-tipped
cutters.
The machine can be used for turning external surfaces, boring, facing
and parting, and turning various cones, radii, and chamfers.
The machine is equipped with a Balt-System NC-310/3 CNC system and
separate drives for the Z, R, X, U, W, and Q coordinates, enabling the
machining of complex surfaces (fill Based on the technical
