The machine mills external gears, both straight-toothed and helical, up to module 40 using the hobbing process and up to module 50 using the single-indexing method. With the internal milling attachment, internal gears are produced for gear rings for large rolling bearings, rotary couplings, and planetary hollow gears, as required in wind power, mining, crane, and shipbuilding technology. Workpieces with a diameter of up to 5000 mm can be accommodated on the 4000 mm table. The milling head pivots by ±45°, and the 82 kW drive power at the milling head allows for both roughing with high material removal rates and finishing with precision.

The machine is equipped with an external teeth milling head - which can process the teeth with an inclination angle from 0 to +/- 45 degrees - and an internal teeth milling head. The machine is composed of a milling unit, a unit for clamping and rotating the workpiece and the pinion axis centering tip. The milling/gearing unit is provided with three translation axes and two rotation axes, as follows: -X axis: longitudinal/radial movement towards the workpiece axis -Y axis: vertical movement of the gearing head -Aza Z: tangential movement of the gearing head -Axis: inclination +/-45 degrees of the gearing head -Axis C: rotation of the main axis of the gearing head The part fixing unit (the machine plate) has a rotation axis, axis B, for rotating the part. 1. External Gearing head – the housing of the tooth milling head is a GG300 gray cast iron cast piece. On the front side there are the counter guides of the Y axis (vertical movement of the head). Inside are the main tool actuation mechanisms, the mechanism for the horizontal movement of the gearing head axis and the mechanism for tilting the gearing head. The main actuation mechanism of the gearing shaft is composed of a 55 kW – S1 motor, a ZF angular reducer and a gearing shaft, mounted in the housing of the toothing horse. Nedjy A Nglepfx Af Sowl 2.
