AVIA AVIATURN 35 CNC turning center

AVIA AVIATURN 35 CNC turning center was built in 2022 in Poland. The machine, designed for precision machining of workpieces with a maximum diameter of 350 mm, has been equipped with many state-of-the-art solutions and high-quality components that ensure excellent turning results. The workspace includes, among others, a 12-position turret and a reliable spindle driven by a belt drive with encoder. The spindle allows both C-axis position reading and constant cutting speed operation for the full range of workpiece diameters.

The AVIAturn 35 CNC lathe is also distinguished by its richly ribbed, single-piece cast iron bed. The bed, which is inclined at 35°, effectively dampens all vibrations and oscillations, resulting in, among others, improved workpiece surface quality and increased cutting tool life. The machine’s extensive equipment includes, among others, a hydraulically movable tailstock, a tool probe and a SIEMENS CNC control in its most powerful version with a wide range of built-in fixed cycles and 16 GB of additional memory. The total weight of the machine is approximately 3850 kg.
