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. -
