Applications of BG500 W2 Spiral Bevel Gear Generating Machine
BG500 W2 is specially designed for the rough and finish cut of non-generated gears of Spiral Bevel and Hypoid Gear sets used in automobile, construction and tractor machineries. When roughing the gear teeth, the plunge-cutting method is used while for finished cutting operation, the Formate method or Helix form method should be adopted. And it is preferable to be used in companion with BG500 D3 for machining pinions.
Main Characteristics of BG500 W2 Spiral Bevel Gear Generating Machine
1. SIEMENS 828D CNC control system, with two numerical control axes, is equipped on the machine. The main motor is a frequency variable motor.
2. When the workhead is on the longitudinal position, it is quick, correct and easy to set-up and take off the workpiece and it is suitable to establish a gear production line. Because of the work spindle being far from the cutter, it is safe to operate the workpiece.
3. The indexing of gear is controlled by the CNC control system and a new-type hydraulic cylinder for the clamp mechanism is adopted on the machine. When the machine is in operation, the work spindle is clamped tightly with the workhead and while in indexing, the work spindle is released for quick indexing.
4. A new-type mechanism controlled by numerical control axis is applied for the axial movement of work spindle, instead of the traditional cam construction, so as to simplify the machine structure and accompany with multi-cutting methods. A hydraulic forced-lubrication is adopted for the cutter spindle in order to increase the rigidity, accuracy and service life of the spindle support.
5. A beam mechanism is adopted for fixing the cutterhead with the workhead. When the workhead is up to the operating position, the beam will be hydraulically clamped for whole operation period and formed as a frame structure.
6. In addition to the hydraulic clamp between the beam and the work spindle, the main cutting force is towards the machine bed, so as to gain the best rigidity based on the heavy weight of machine.
7. Tooling and fixtures of the existing Gleason Nos.606, 607, 608, 609 and 610 machines can be used on this machine. Dimensions for connecting the cutters are 58.221mm, 126.966mm and 215.8mm respectively.
8. All kinds of protective measures, such as pressure protection, lubricating protection and indexing protection, have been adopted on the machine, so as to get the reliability of machine operation.
9. The machine is equipped with an auto chip conveyor and air conditioner for the electrical cabinet.
