G 80
Thanks to its outstanding grinding performance and universal design, this CNC-controlled bevel gear grinding machine from the G model series is an extremely economical concept for high-precision final machining of the curved-toothed bevel gears of any gearing system as well as face-type clutches. These machines operate up to a ring gear diameter of 850 mm. The G machines are equipped with a side loading door for automation purposes, making loading using handling robots easy during automatic operation.

* With large outside diameter, the smallest spiral angle must be checked dependent on the axis traversing path.
The above-mentioned maximum values were determined for industry-typical gear units.
If necessary it has to be examined whether maximum values can be combined.
Subject to changes.
The machine dimensions of the standard version are for orientation only. The final machine dimension / final space requirement depends on the individual configuration of the machine.
