PORĘBA TCA 160 heavy duty lathe

PORĘBA TCA 160 heavy duty lathe was built in 1959 by the Polish PORĘBA Mechanical Equipment Factory. The lathe processes a detail with a maximum weight of 16 tons. The maximum turning diameter of the machine above the bed is 1600 mm, over the carriage is 1300 mm, while the turning length is 6000 mm. TCA 160 has tusks with a distance of 3000-15000 mm and a rise of 800 mm. The spindle rotates at a speed in the range of 1.12 to 224 revolutions per minute.
