General purpose·Compact Multi-function machine to include skiving function Best for gear machining for automotive parts Compact equipment with flexibility to cope with the various kinds of small quantity production and multiple processes Hard-skiving achieves high-precision machining of hardened gears Interactive operation screen provides excellent man-machine interface

High-efficiency gear skiving and integrated process
remarkably reduce machining time

Multiple process in one machine

To achieve compact production lines by reducing floor space
with 3 roles in 1 machine

Superior workability and operability

Interactive operation screen for skiving (optional)

• Crowning process and run-in amount modification function (initial mode)
• Newly added tool compensation setting and workpiece coordinate system preset
  All machining conditions for skiving can be set
