Floor Type Horizontal - HBA-QF Series
-Fully utilize the axes strokes and table size.
-The cross section of each major body structure has been increased to 150% of the industrial normal type, and distortion ratio reduced 200% providing superior dampening capability.
-Heat and friction were minimized at the lowest level to assure excellent precision. Circulating, cooled spindle oil is employed to provide a mist-lubrication of the spindle bearings, and a coolant jacket for outer spindle and spindle motor flange.
-The slideways are force-lubricated, and all moving components are free from heat and distortion.
-With over a century of superb craftsmanship, hand scraping technique makes mechanical contact surface smoother, and ensures the machine precision. Hand scraping techniques can achieve the flatness and straightness that machine cannot achieve.
-The spindle undergoes nitriding process to achive hardness over HS95. The super-finish grinding makes the mirror-like spindle surface.
-The spindle quill perform the curburizing and quenching treament, the surface hardness can achieve over HS78 The super-precision thrust bearing can maintain the space between the spindle, which can keep the machining accuracy for long time.
-The maximum torque of spindle 3970Nm (405kgf-m).
-Since the bearing components of the spindle are equipped with a mist lubrictation, and the outer spindle and motor flange employ an oil-jacket cooling system, they are free from heat and distortaion caused by friction.
Boxed Type Structural Design
-With the rib arrangemet and large cross-sectional area, high rigidity, stability, and resistance to vibration can be achieved.
-The driving power is transmitted from servo motors to ball screws by couplings on X, Y-axis, preventing backlash fro accurate contouring commands. The large diameter Z-axis ball screw incorporates a gearbox to generate the maximum continuous thrust force of 3,000kg.
