15KVA CNC Gear Cutting Machines For Zero Bevel Gears, High
Precision Siemens System:
This machine family is designed to cut, with many cutting methods,
spiral bevel gears, hypoid gears and zero bevel gears of diameter
up to 320mm and module up to 6mm. It is especially suitable for
roughing and finishing, in mass production, spiral bevel gear pairs
used in the light-duty vehicles, auto rickshaws and quad bikes.
This machine family consists of three modular-design versions:
YK2232/ YK2232A/ YKW2932, and their functions are:
The YK2232 CNC spiral bevel gear generator is a general-purpose
machine for roughing and finishing the gears and pinions.
The YK2232A CNC spiral bevel gear generator is a version with a
cutter tilt mechanism. It is not only used for cutting the Formate
pinions but also for the “cutter tilt modifications” of the tooth
bearings. It’s preferable to be used in companion with the YKW2932
CNC spiral bevel gear finisher.
The YKW2932 CNC spiral bevel gear finisher is mainly used to cut
ring gears high-efficiently with the Formate method, and at the
same time this machine can be changed into a universal spiral bevel
1. Machines in this family are CNC spiral bevel gear cutting
machines with the cradle roll and the sliding base feed.
2.These machines are 3-axis CNC machines, 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.
The machines adopt the Generating method and the Infeed method and
Modified Roll and Cutter Tilt methods as well. A SIEMENS 802 DSL
CNC system and a digital servo system are standard.
3.Cutter spindle rotations are controlled by means of a frequency
variable motor for the stepless speed regulation.
4.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 YKW2932 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.
5.To ensure the gear finishing rigidity of the YKW2932 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.
6. A cutter tilt device with maximum 30° tilt angle is equipped on
the YK2232A machine to cut the Formate pinions and modify perfectly
the tooth bearings to cut Generating-forming pinions so as to get
better tooth bearing modifications.
7. No change gears should be changed on machines of this family,
thus shortening the time for the machine set ups.
8. Machines of this family is easy to be operated and facilitates
the improvement of productivity.
9. CNC control system, main electrical and hydraulic components,
critical bearings and sealing are fine quality products or world
well known brands, which guarantee the machine reliability.
10.The machine is equipped with an independent sealed electrical
cabinet, with an air conditioner.
11. A machine enclosure and an auto-chip conveyor are equipped on
12. Both the energy consumption and the floor space of the machine
are less. The investments of the machine are a few and may be
