Features of BG320 W3 Spiral Bevel Gear Finishing Machine
1. BG320 W3 Spiral Bevel Gear Finishing Machine is mainly used to cut ring gears efficiently with the Formate method, and it can be changed into a universal spiral bevel gear generator, and it is preferable to be used in companion with BG320 D3 for machining pinions.
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, and a gear backlash eliminating device is adopted for the work indexing of the BG320 W3 machine in order to enhance the machine structure and the transmission rigidity and to guarantee the machining accuracy, to improve the productivity and to prolong the service life.
6. To ensure the gear finishing rigidity of the BG320 W3 finisher. a Y-axis indexing device, a hydraulic backlash elimination device and a lock device for the X, Y and Z axes are equipped on the machine,
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.
