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. 2. Internal 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. 3. The Quill - has the role of fixing the high parts, having a vertical displacement stroke. Dedpfx Aksy A Nglovokr 4. The longitudinal advance mechanism of the upright, X axis – is made by a servo motor 30 Nm_ 3000 rpm, a Gressner worm reducer and a ball screw diam. 80 x 10, accuracy class IT 3. 5. The vertical advance mechanism of the toothing head, Y axis – consisting of a 30 Nm_ 3000 rpm servo motor, a Gressner worm reducer and a ball screw diam 80 x 10, precision class IT3. 6. Plate advance mechanism / plate rotation, C axis – is made with two 50 Nm_ 2000 rpm servo motor, a Gressner worm reducer and a duplex worm that meshes with the worm crown located on the plate. 7. The gearing head tilting mechanism, axis B – is made by a / 20 Nm_3000 rpm servo motor, a Gressner worm reducer and a worm gear-segment worm gear transmission. 8. The axial displacement mechanism of the gear head, Z axis – is made by a 20 Nm_3000 rpm servomotor, an Alpha Getriebe planetary reducer and a ball screw diam. 63 x 10, accuracy class IT3. 9. Top horizontal positioning mechanism, auxiliary axis X1 – a 20 Nm_ 2000 rpm servo motor, an Alpha Getriebe planetary reducer and a ball screw diam 63 x 10, precision class IT5.
