STAR ECAS 32T CNC lathe

STAR ECAS 32T CNC lathe was built in 2005 in Japan by STAR MICRONICS CO., LTD. The machine, designed for the precise machining of complex workpieces, is used in many industries, such as automotive and aerospace. Its extensive machining capabilities facilitate complex machining processes, such as turning, drilling and threading, both on the front and back of the workpiece.

Compared to other lathes available on the market, the offered STAR ECAS-32T swiss-type lathe stands out with the use of 11 axes, two 10-position turrets and two spindles (main spindle and sub-spindle). The extremely rigid design, in turn, provides the incredible process stability which is necessary to achieve excellent precision and quality of the produced parts. All this is complemented by intelligent CNC control, in which even the most advanced work programs are created in just a few steps. The STAR MICRONICS ECAS 32T CNC lathe weighs 5700 kg.
