3 Axis CNC Gear Shaping Machine For Large And Medium Gear For
This machine is a large-size and heavy-duty gear shaper specially
designed for cutting the rotating bearings used for the
construction machinery, large and medium size speed reducers,
mining machinery and wind-mill generating equipment, and the
internal and external ring gears used for the national defense and
military industries. Helical spur gears may also be accommodated on
special request of the customer when a helical guide and a cutter
with helical teeth are equipped.
1) This machine is a CNC gear shaper with 3-axis simultaneous
controlled movements, which are the cutter spindle rotation
(X-axis), the worktable rotation (Y-axis) and the radial feed of
the worktable (Z-axis).
2) The reciprocating movements of the cutter spindle are driven by
means of a powerful frequency-variable motor with the
frequency-variable speed control. In order to ensure a sufficient
cutting force of the cutter spindle, automatic and stepless speed
regulation and auto speed changeover are possible.
3) A SIEMENS 802D-SL CNC control system or 840D CNC control system
(optional) and a digital servo system is equipped on the machine.
CNC control systems and servo systems of other brands are available
4) The 2000mm diameter face plate on the worktable has a high
loading capacity and is easy for mounting the workpiece and the
5) The cutter spindle can stop automatically at the up-stop
position. This facilitates the rapid withdrawal of the workpiece
6) The oscillated cutter relieving mechanism is adopted for the
cutter relieving, which is reset by means of a sauce spring and the
cutter relieving direction is adjusted conveniently, so as to
obtain the stable movements, a low noise-level and a high rigidity.
The repeatability of cutter relieving ≤0.01mm.
7) The machine has a free-standing sealed electrical cabinet
equipped with an air conditioner and a movable console for the easy
8) A safety enclosure is equipped on the machine to prevent the oil
from being splashed out and provide better viewing of the working
9) The machine adopts a large-volume oil cooling for the timely
cutting heat dissipation and the stable accuracy. An automatic chip
conveyor is available.
10) A riser and adaptors for different cutter diameters can be
available on special request.
11) The accuracy of gears machined on this machine may reach Grade
6 of the GB Standard.
Main Features of Machine:
1) With an excellent integral rigidity, the structures of the
machine bed and the column are fine and the static and dynamic
rigidity is supreme, together with the stable performance and the
2) The reciprocating movements of the cutter spindle are performed
by means of the up to date zero-degree large diameter worm, which
is just the cutter spindle itself and provides the constant cutting
force during the whole machining operation. The powerful
oscillations of the segmental worm wheel drive the reciprocating
movements of the cutter spindle.
3) The worktable is driven by means of a high precision, larger
diameter ball screw to perform the radial feed and improve the
4) The feed guideways are of high rigidity and fine guiding
5) The large diameter worktable has a unique load relief device and
it is especially suitable for cutting heavy-duty workpieces. Such a
worktable may prolong the service life of the worm and worm wheel
pair of the table.
6) The machine has an angular cutter relieving function in order to
avoid interference between the cutter and the workpiece.
