Description
1.
Main
drive
of
this
series
machine
is
taken
from
D.E.
stepless
speed
regulation
,and
table
adopts
hydrostatic
guideway.
2.
The
machine
has
functions
of
turning
and
milling
,the
left
head
is
universal
turning
head,but
right
one
is
of
CNC
head.
3.
The
crossrail
is
fixed
with
hardened
steel
strips
.It
adopts
unloading
as
to
keep
the
crossrail
horizontal
accuracy.
4.
The
machine
adopts
SIEMENS
840D
system
in
half
closed
loop
control. |
5.Feed
system
is
driven
by
AC
servomotor
which
is
connected
with
ballscrew
by
flexible
couple
to
implement
clearance-free
transmission
and
high
precision
turning.
6.The
columns,
whose
thermal
symmetric
construction,
is
calculated
by
finite
element
method,
stand
on
table
base.
Effective
vibration-insulated
method
is
adopted
to
ensure
high
rigidity
and
strong
anti-vibration
ability.
7.The
table
is
thermal-symmetric
construction.
The
spindle
is
centered
by
high-precision
double-row
short
cylindrical
roller
bearing
whose
radial
clearance
can
be
adjusted.
With
large
high-precision
thrust
ball
bearing
on
axial
direction
as
rolling
guideway,
and
oil
temperature
cooling
device,
the
table
has
high
swiveling
precision,
larger
load
ability
and
smaller
deformation.
8.Linear
dual-direction
roller
guideway
is
applied
to
ensure
high
effective
transmission
and
good
precision
reliability
in
heads
and
ram
feed
movement.
9.CNC
system
is
SEMENS
or
FANUC
system,
and
other
CNC
system
is
also
can
be
provided
on
customers?special
requirements.
10.Chip
conveyer
and
half-closed
guide
are
also
equipped
by
costumers'
reguirements.
11.On
customers'
requirement,
the
followings
can
be
supplied:
Magazine,
built-in
tool
setting
device,
boring
&
milling,
table
indexing
and
feed,
grounding
cooling
device,
left
head
and
whole-loop
control,
etc. |
