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.

  • 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

BT-50 SHORT END SPINDLE
Spindle speed:4,000rpm. BT-50 taper adopts short spindle end design with use of gear box. This is suitable for heavy cutting. Spindle torque could reach 572Nm, and 6,000rpm spindle is available.

BT-50 EXTENDED LONG-END SPINDLE (opt.)
The design of the extended long-end spindle is especially suitable for deep hole machining. BT-50 inside hole taper and 6,000rpm spindle are standard design. 8,000 rpm spindle is available. It is very suitable for large mold machining.
