Simultaneous 5-axis machining: B-axis NC control (optional)

〈Process-intensive machining of large spiral bevel gears〉

Process-intensive machining on one multitasking machine of processes normally done on three different machine types, including expensive special purpose machines. Not only are equipment costs and installation space greatly reduced; lead times are also a significantly shortened.
High-accuracy machining is achieved with simultaneous 5-axis control (B-axis NC) and a highly accurate C axis.

Single pitch accuracy JIS Class 5
(former JIS grade 1)
Accumulated pitch accuracy JIS Class 2
(former JIS grade 0)
  • Main specifications:
    B-axis NC control
    High-accuracy C-axis
    Super-NURBS (high-speed contouring)
Tooth surface finishing
