ND series

Standard model to realize high accuracy and economic efficiency by easy operation.

Equipped with control function such as easy set-up, change of revolution speed/expansion pressure to pursue easy operation.
The low cost was achieved to meet the request of accurate specification by adopting hydraulic control for spindle reciprocating.
