Nanoshape T250

 Ultra Precision Turning Machine (Nanoshape T250)

Nanoshape T250 is a highly stiff & precision turning machine, developed by CMTI, capable of Single Point Diamond Turning (SPDT) & Ultra precision hard turning equipped with state of the art technologies for producing non-ferrous, ferrous and IR material components with optical quality surface finish (surface finish in the order of few nanometers and form accuracy in sub-micron range). The Nano level surface finishes achieved on components are in the magnitude of ≤ 2 nm Ra*. The machine has excellent static, dynamic and thermal behaviour and has accuracies in order of nanometres.
