Main Characteristics of BG125 C3 Spiral Bevel Gear Generating Machine
1) BG125 C3 Spiral Bevel Gear Generating Machine is designed to operate as three-axes CNC control spiral bevel gear generator, i.e. cradle oscillation (X axis), work spindle rotation (Y axis) and sliding base movement (Z axis) being simultaneously controlled by control system for cutting the gears. The rotation of cutter spindle is controlled by a frequency variable motor for its stepless control.
2) This series of machine is easy to adjust, with setting up the procedure for generating, indexing, infeed, cutter speed and cradle reversing according to requirements of different cutting method, meanwhile the productivity of machine has a great increase.
3) When setting the cutter by hand, the power of main motor will be off, so as to protect the operator. There are soft & hard over-travel protection for Z axis.
4) A high precision cylindrical gear pair is used on this series of machine, which keep high dynamic rigidity and high precision cutting for tooth flank. The cutting accuracy of gears can reach Class 6 steadily.
5) This machine is equipped with SIEMENS 828D to accomplish the automatic or manual control and fault diagnosis.
6) This series of machine is equipped with an independent close type electrical cabinet with an air conditioner.
7) Overall sealed safe guard and auto-chip conveyor can be provided on this series of machine.
