MAIN
FEATURES
The Model YX3120CNC, YX3132CNC and YX3140CNC are CNC
High-Production Gear Hobbing Machines with the following 4 axes working
under the CNC control: Radial feed axis (X-axis), axial feed axis
(Z-axis), hob spindle running axis (B-axis) and worktable running axis
(C-axis).
The main drive to the hob spindle is transmitted from
an AC main drive motor (mounted on the hob head) via 3 high-precision
cylindrical gear pairs. The main drive motor has a power of 11KW or 15KW
enough to undertake great cutting force. A multi-start hob can be used
on the machine to make heavy cut.
The major guideway pair is composed of wide
rectangular guideways and Teflon-coated slideways. The ballscrews are
rigid in transmission, great in actuating capacity and high in linear
movement accuracy. The counter-balance cylinder on the column is coaxial
with the ballscrew, thus making it possible for the hob head slide to
move up and down in better balance.
As a standard collocation, the machine is equipped
with a Fanuc Oi+EGB control system and a communication interface RS232C
for connection with a personal computer.
These machines are designed for cutting cylindrical
gears, helical gears, short spline shafts, sprockets and wormwheels.
These machines are also capable of cutting various little tapered teeth
gears, crowned teeth gears and gears with special tooth profiles.
These machines are well-suited for batch and mass
production of gears in the heavy-duty automobile, construction machinery
industries, but also well-recommended for small batch production of
different gears in the gear-making enterprises.
