802D Siemens CNC Bevel Gear Generator For Small Size Spiral Bevel
This is a new series of CNC machine produced on the base of our
experiences for developing spiral bevel gear generators and
application of CNC technology in many years, with modern design
method and integrative technology of mechanics and electronics.
This series of machine is suitable for cutting small size spiral
bevel gears used for automobile and motorbike industry, and for
cutting fine spiral bevel gears used for top grade sewing machine
and power tools. It is most suitable for batch production as well
as suitable for mass or jobbing production.
1) This series of 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 limit
switches 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 series of machine is equipped with CNC control system 802D
(SIEMENS) or FANUC CNC 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.
