Introducing the HAMAI N70. Under the design concept of "COMPACT BUT POWER
FULL", this machine was developed. It’s a quantum leap forward, for exceptionally fast
production of high precision aerospace, automotive and shaft gears up to 120 mm in diameter,
and cutting capacity to M2.5. Exceptionally easy to operate using the interactive input with
graphic display, and available fully automated to reduce load/unload time by adapting the slant
type hob head.
APPLICATIONS
Hobbing (axial, radial/ axial) of spur and helical gears using one or multiple cut technology using climb or conventional feed with HSS or carbide hobs:
- disk and shafts type workpieces
- spur and helical gears
- cylindrical, crowned or tapered gears
- special profiles (e.g. splines) with special tools
- worm gear hobbing
- The above-mentioned technical data may vary depending on the geometry of the workpiece to be machined and on the loading system and work holding fixtures used.
