EXCELLENT FEATURE INTENSITY
|
|
Spindle Box :
Assume optimization cross-section modulus rectangular proportion 1:1.125 (400mm:425mm) and reinforced by interior rib frame . The roller-rail RGH linear guideway that length cover-rate 56~76% can advance the cutting feed, rigidity and stability.
|
|
Slider :
Unique design of multistep track support has four block on bottom-way and tree block on top-way of HGH linear guideway that length cover-rate 56~76% . The advantage of slider are high intensity and high stability.
|
|
|
|
BEST FEEDING STRUCTURE SYSTEM :
|
|
The three spindles used the C3 level precision ball screw.
The end point suitably advanced tighten. To reduce the screw's heat temperature, all machine used with the absolute coordinates system.
To remove the machinery complex structure for both side of ball screw designed anti-collision protective device.
|
|
|
|
Crossbeam :
The box-in-box and multistep structural design has best moment of inertia and guarantees Y and Z travling dynamic accuracy performance. Compare with other competitor hollow-beam , the strength/weight ratio higher 20% .
|
|
Column :
Use box-in-box structural design replace with hollow column,which is 25% heavier than other competitor their products. The column and crossbeam their linking surface adjusted by hand scraping. The verticality, flatness increases the structure stiff rigidity.
|
|
|
|
|
|
Base :
The box-in-box structure with big ribs and the unity forming frame of chip groove (FD18 series), the base design for three linear guideways (FD24,FD28, FD32 series) that get greater rigidity and dynamic accuracy even heavy loading.
For example FD-2842 base weight (20ton) more 30% than other competitor base.
|
|
|
Working Table :
Unique double deck enclosed structure which bottom matched with high rigidity block of HGH linear guideways that length cover-rate 25%.
Improve rigidity and stability and load (average load 12000 kg/m2).

PRODUCTS CHARACTERISTIC
|
|
Excellent structure rigidity : Rigid structure is essential condition of double column machining center. Our machine structure used high quality cast iron MEEHANITE GC-275 processing with tempering , that make more rigidity and stability. The structural sharp has designed by Finite Element Analysis (FEA) enables to display the best rigidity and anti-seismic property.Therefore can prevent cutting resonance occured, promote the effective accuracy and increase the cutter life.
|
|
Excellent spindle box characteristic : Spindle box designed with rectangular proportion 1:1.125, the optimization cross-section modulus can provide the Z axis traveling rigidity . The spindle box interior strengthens by the middle partition and arc rib, can advance the cutting feed stability.
|
Best Z axis balance response system :
The loop double N2 tank counter-balance that can provide the Z travel completely systematic and demand of the strong force thrust processing.
It designs with central symmetrical spindle system, the spindle, motor, ball screw and the loop counter-balance makes the best spatial disposition.
This unique design allows the machine to remain stable when the temperature rise. Even if the emergency power off will not occur the slide down, also guaranteed that the cutting tool work security.
|
|
|
|
|
Best tool exchanging system :
The spindle coordinate with the floating-type of hydraulic exchanging tool system. When loose the tools, the main spindle bearing is not affect with hydraulic balance their external force, also guarantees the spindle accuracy and life.
|
Best the feeding system :
The X and Y axis used with the HGH series, the Z axis uses with the RGH series linear guideway, picks the heavy load, the high accuracy P level linear guideway has 0.003~0.005 low friction and the driven sensitivity, to promote the dynamic accuracy.
|
Best feeding structure system :
All three travels used the C3 level precision ball screw, besides the design anti-collision protective device. The end point suitably advanced tighten to reduce the screw's heat deformation.
All machine used with the absolute coordinates system to match with the optical scale, to reach the working accuracy requirements.
|
Stong spindle cutting power :
The spindle uses BT50# diameter Ø100mm, uses the P4 level precision ball bearing speed to be possible to reach 6000rpm above.
The machine uses Japan FANUC  series high torsion,
high powered spindle motor, and matches with German ZF-DOUPLAN precision high low-grade gear box.
To deal with various fields of cutting condition to provide sufficient horsepower and the torque output.
|
Best working space :
The motor base and the gearbox set on the spindle box up, which may deepen the cutting depth reaching 1300mm above. When set up 90° side milling head,
the Y-travel processing will not reduce because crossbeam length (Y-travel) increases 600mm relatively.
For example: the maximum cutting space of FD3260 is 6000mm x 3800mm x 1100mm.
