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.
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.
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.
