LH20 twin spindle and driven tool holder CNC machine tool is a
5-axis (3-axis synchronous motion) tuning center full function CNC
machine tool. The monolithic bed structure with 45 slant guideway
features high performance and high stability to the perfect working
scheme. It possesses the most advanced control system and driving
technology. It’s a excellent machine of combined turning machining
with high accuracy, high stability and high efficiency. The
combination of the work procedure reduces the frequency of clamping
the workpiece and improves the precision of the machining.It
realizes the possibility of turning around the workpiece because of
twin spindles. Therefore, this product is quite suited to machine
those parts of highly concentrated work procedure. The high
accuracy self-lubricating rolling guide screws, which features high
positioning accuracy, dynamic characteristics, fast movement speed,
are adopted not only for the longitudinal and transverse guide
ways, but also for the longitudinal and transverse guide screw. Due
to the self-lubricating structure in the moving components, the
environmental protection level is upgraded to the limit, and the
fuel consumption cost is lowered to the minimum. Equipped with
German SIEMENS high performance 840D CNC systems, the machine is
allowed to install 12 power cutters in 12-station power turret at a
time.
Machine characteristic：
Monolithic cylinder reinforcement bed. The side chip removal or
rear chip removal are optional. The chip and water receiving tank
with water oil separating structure are attached.
High accuracy rolling guide rail pair. Good dynamic performance and
kinematics accuracy.
The primary drive system is driven by high performance AC spindle
servomotor. The transmission without gears and closed greasing
structure are adopted in the headstock.Highest speed of spindle
reaches 5000r/min.Low noise, low heat emission, and smooth
operation. The X and Z axle are driven by AC servomotor. The closed
loop control is optional.
Angular contact ball bearing assembly is adopted as the fore and
rear bearings of spindle to provide the sufficient endurance of the
radial and axial load caused by the heavy cutting.
The original Italian electric power turret is adopted, so as to
fulfill the heavy cutting under high rigidity. Select the nearest
cutter from both sides. Extremely short time to exchange the
cutters improves the productivity.
It adopts hydraulic power spiral chuck and hydro cylinder.
The axial movement of right spindle, in other words W axis movement
is driven by ball screw, which is controlled by NC.
The self-lubricating (greasing) is adopted in various moving
components, which drastically reduces the oil consumption, so as to
furthest avoids the environmental pollution.
Special designed separation structure of chip cleaner and water
tank make it easier to clean the water tank. The high-lift flexible
pump is used in the cooling system to improve the cooling
performance of the parts procession.
