High-Rigidity, High-Precision & High-Efficiency Design Concept High-Rigidity
- The cross-beam is designed with three roller linear guide ways in
45-degree, large span, configuration. This design provides 35% more
stiffness than parallel designs with two linear guideways.
- The Y-axis is designed with 65mm roller type linear guide ways, which is
larger than on same type machines in the market width of 55mm.
High-Precision
- The Z-axis structure has four 45mm heavy-duty type roller guide ways.
This design ensures highest possible rigidity and long term precision.
- Positioning Accuracy ±3μm/300mm(JIS 6338)。
High Horsepower, High Rotational Speed, High Stability
- 35-HP spindle motor, 6,000 RPM two-steps automatic change gear box.
- Output torque of 642Nm(ZF gear box), offers capability of low-speed
heavy cutting and high-speed precision cutting with extensive process
range. (For demand of higher torque, please contact with our sales
department).
Auto TooL Change System
- Max. tool diameter of 125mm &, Tool length of 350mm.
- Auto tool change time is 8 sec. (Tool to Tool)
Process Ability
- Y-axis travel: 1,600mm/2,100mm/2,600mm
- Z-axis travel: 1,000mm (standard)
- Z-axis travel: 1,200mm (option)
- Width Of Table: 1,500mm/2,000mm/2,500mm
Unique X Axis Transmission System
- Advantage of direct transmission leads that the leadscrew
can rotate with no influence from belt tention.
- Direct transmission with speed-reduction mechanism is
added to X-axis to increase the transmission torque, the
thrust, and the capacity for workpiece weight.

Spindle Head View Picture
- The Z-axis structure has four heavy-duty type roller guide
ways (with way width of 45mm) ensuring high rigidity at
the spindle head. The extra heavy-duty roller guide way
is designed with more sliding blocks and more linear
guide ways, which evenly share the loads. The design
offers characteristics of stiffness and rigidity, long- term
precision and low wear. It has excellent ability to perform
accurate micro movements. The structure provides
excellent machining capacity, better surface finish and
guarantees good accuracy for long-term operation.
- Low friction coefficient for the four roller guide ways.
- The saddle design for the spindle head reduces the
deformation of X-axis caused by cutting forces.
- Z axis structure is symmetrical design to prevent from the
dissymmetrical heat deformation.

X Axis Transmission Way
Direct transmission provides the following advantages for
the speed reduction mechanism:
- The ball screw rotates with no influence from belt tension.
- The responses of the motor are directly sent to the ball
screw.
- The backlash is minimized.
- The positioning accuracy is excellent.
- The torque and the thrust forces are increased.

Perfect Structure Design High Quality Guarantee
- The new design structure with large span and heavier casting offers maximum rigidity.
- The cross-beam with three 65mm roller type linear guide ways. Because the loads are shared between more linear guides and more blocks, both life time and rigidity increase.
- The cross-beam is designed with three roller linear guide ways in 45-degree, large span, configuration. This design provides 35% more stiffness than parallel designs with two linear guideways.
- One-piece construction design is Amga's persist in design concept. High-stability body provides capability for higher accuracy machining. It is not only able to carry a heavy workpiece, but also to perform heavy cutting with the highest-level accuracy
in industry.
- When table width is more than 2,000mm, the base is designed to be evenly supported by four roller-line rails (rail width 45mm). The design is appropriate for carrying load and increases the life of the linear guide ways, reduces deformation of
table, and meets the requirement of machine accuracy.

CHARACTERISTICS OF THERMAL-DEFORMATION COMPENSATION SYSTEM
- The thermal deformation compensation system includes measurement of thermal deformation, thermal deformation
math model developed based on measured thermal deformation, and compensation card that executes the compensation
process. It enhances machining accuracy, solves thermal deformation problem, and increases the cutting accuracy.
|
THERMAL DEFORMATION COMPENSATION MODEL IS THE ADVANTAGE FOR
MOLD MAKING INDUSTRY
- Spindle & structure thermal deformation compensation.
- Overcome the influence of ambient temperature.
- Suitable for long machining hours with the same accuracy for mold making.
- The machine can work anytime, no need to warm the machine in advance.

Different Types Of Spindles Are Available |
|
GEAR- DRIVEN SPINDLE
The gear-driven spindle provides spindle speed of 4,000rpm and 6,000rpm with high output torque which is the best
choice for frequent heavy-cutting operations. |
|
ZF SPINDLE
ZF spindle has higher torgue than belt-driven spindle. ZF spindle provides higher rotational speed than gear driven
does. ZF gear box has 1:4 speed reduction ratio mechanism.
It enlarges output torque by 4 times. It offers an extra choice
for users who needs high rotation speed and high torque for
machining operation. |
|
CROSS-BEAM BACK HOLDER DESIGN
The design of the back holder of cross-beams neatly aligns hydraulic unit, cooling machines, and spare parts, etc., and
meets the requirement of CE regulations.
This design offers two advantages:
1. More free spaces for operators
2. Easy to maintain |
