1 Gear Hobbing Unit High Productive Manufacturing of Gears with CNC Turning Centers. Maximum flexibility, high quality, optimal handling. In operation:

quality according to standard 8 ISO 1328, AGMA 8

runout accuracy Interchangeable milling arbor

change through removable counter support and

tools can be pre-set interchangeable milling

2 Gear Hobbing Unit Gear Hobbing Unit for Turn/Mill Centers Usable for machining gear quality according to standard 8 ISO 1328, AGMA 8 Maximum scale swing of ±30 High stiffness and runout accuracy Interchangeable milling arbor available in different sizes Easy cutting tool change through removable counter support and withdrawal of the complete milling arbor Cutting tools can be pre-set interchangeable milling arbor Angular adjustment ±30 with scale and vernier removable counter support 2

Operation principle: Gear hobbing Sample workpieces z n c

z c n Feed movement in Z axis. Splines e.g.

has to be sufficient clearance for the hob.

To optimize the cutting tool life you can move the hob step

3 Operation principle: Gear hobbing Sample workpieces z n c Synchronization of work piece and tool rotation. z c n Feed movement in Z axis. Splines e.g. DIN 5480, DIN 5482, TORX x When hobbing is finished the hob has to move towards X. c n Please consider: At the end of the gear/spline there has to be sufficient clearance for the hob. Shifting Spur gear n c Initial hob position after tool change with new cutting tool. y n c Hob position at end of cutting tool life. To optimize the cutting tool life you can move the hob step by step in Y axis direction. This movement enables the usage of all cutting edges of the hob. This procedure is called shifting.
