| Machine Description | ||
| The NOMURA NN-20J3XB CNC Swiss-Type Automatic Lathe builds on the proven 20J3 platform and provides B-axis flexibility for multi-angle drilling and milling operations in a single setup. Type A incorporates a programmable B-axis on the main spindle side, while Type C expands the machining capability with B-axis functionality on both the main and sub spindle sides. This configuration is particularly suitable for complex precision components requiring high done-in-one machining capability and reduced secondary operations. |
