STAR ECAS 32T CNC lathe

STAR ECAS 32T CNC lathe was built in 2007 in Japan by STAR MICRONICS CO.,LTD. The machine, which combines high performance and precision, has been designed to improve the machining of even the most complex workpieces. Its extensive machining capabilities facilitate complex machining processes such as turning, drilling and threading, both on the front and back of the workpiece. This makes the STAR MICRONICS ECAS 32T CNC lathe indispensable in many industries, such as the automotive and aerospace.

The STAR ECAS-32T swiss-type lathe is equipped with, among others, 11 axes, two spindles (main spindle and sub-spindle) and capacious turrets that can accommodate many tools for any type of machining. The maximally rigid design additionally ensures incredible process stability, which is essential to achieve excellent precision and quality of the produced parts. The total weight of the machine is 5700 kg.
