Features of BG320 D3 Spiral Bevel Gear Generating Machine
1. BG320 D3 Spiral Bevel Gear Generating Machine has cutter tilt mechanism. It is not only used for cutting the formate pinions, but also for the “cutter tilt modification” of the tooth bearings, and it is preferable to be used in companion with BG320 W3 for machining gears.
2. This machine is 3-axis CNC machine, i.e. the cradle roll (X- axis), the work spindle rotation (Y- axis) and the sliding base movement (Z- axis), and 3-axis simultaneous movements are possible.
3. The machine adopts the Generating method and the Infeed method and Modified Roll and Cutter Tilt methods as well. A SIEMENS 828D CNC system and a digital servo system are standard.
4. Cutter spindle rotations are controlled by means of a frequency variable motor with an override switch for the stepless speed regulation.
5. A high precision worm and worm wheel pair with a dampening device is used for the cradle drive and the work spindle drive respectively.
6. A cutter tilt device with maximum 30° tilt angle is equipped on the BG320 D3 machine to cut the Formate pinions and modify perfectly the tooth bearings to cut Generating-forming pinions so as to get better tooth bearing modifications.
7. No change gears should be changed, thus shortening the time for the machine set ups.
8. Easy to be operated and facilitates the improvement of productivity.
9. The machine is equipped with an independent sealed electrical cabinet, with an air conditioner.
10. A machine enclosure and an auto-chip conveyor are equipped on the machine.
