Tur 3MN
The TUR 3MN is a lighter version of the 4-rail lathe. It allows machining of details up to a diameter of 1,900 mm.
The design allows for precise joining of segments, thanks to which TUR 3MN and 4MN lathes can be built in various configurations, depending on individual configurations of needs.
