CHARACTERISTIC

 

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.
  • ±3μm/300mm(JIS 6338)。
  • 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 quide 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 dissymetrical 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 tenson.
  • The responses of the motor are directly sent to the ball screw.
  • The backlash is minimized.
  • The positionning 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 accuraey 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 requiremrnt of machine accuracy.

 

 

 CHARACTERISTICS OF THERMAL-DEFORMATION COMPENSATION SYSTEM

  • The thermal deformation compensation systerm includes measurement of thermal deformation, thermal deformation math model developed based on measured thermal deformation, and compensation card that executes the compensatioin process. It enhances machining accuracy, solves thermal deformation problem, and inreases 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.
  • he machine can work anytime, no need to warm the machine in advance.

Different Types Of Spindles Are Availbale

bd2217-8228_3.jpg

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.

bd2217-8228_4.jpg

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 outpt torque by 4 times. It offers an extra choice for users who needs high rotation speed and high torque for machining operation.
bd2217-8228_5.jpg

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.
