Applications of BG800 G3 CNC Spiral Bevel Gear Grinder
BG800 G3 CNC Spiral Bevel Gear Grinding Machine is designed as a CNC Control high precision finishing equipment for grinding Spiral Bevel and Hypoid Gears with module up to 15mm and diameter up to 800mm. This is a universal machine and most suitable for mass production as well as jobbing production of gears. This machine is widely applied in finishing the high precision Spiral Bevel and Hypoid Gears in machine Building Industry.
Main Characteristics of BG800 G3 CNC Spiral Bevel Gear Grinder
1. The machine is equipped with SIEMENS 828D CNC Control System (resolution ratio 0.001mm) and it is of a three-axes CNC machine, cradle (X axis), work spindle (Y axis) and sliding base (Z axis) being simultaneously controlled by CNC control system.
2. The rotation of grinding wheel spindle is controlled by a frequency variable motor for the advantages of stepless control, no change gears, programmable order, direct operation, convenience and flexibility.
3. Also, dialogue program can be adopted on the machine. In this case, the operator with mechanical operating experience can easily and observably control the machine.
4. The cradle and work spindle are driven by servo motors through precision worm gear sets while the sliding base is driven by servo motor via precision ball screw.
5. The conventional mechanical driving system has been simplified for the purpose of the change gears, minimizing the setting time of machine, short as the driving chain and increasing the machine accuracy as well as making the machine operation correctness and convenience.
6. The machine is equipped with an independent sealed electrical cabinet, which may be equipped with an air conditioner.
7. Safety guard and independent cooling tank are provided with the machine.
