CNC DOUBLE COLUMN MACHINING CENTER Excellent Structural Strength Optimal Spindle Head Outstanding Feed System Outstanding Z-axis Balancing System Extra Power Cutting Capability

Excellent Structural Strength : The structural parts are designed by means of "Finite Element Analysis" to achieve the maximum rigidity and dampening capability. This will avoid resonance that may affect machining accuracy while extending tool service life and machining performance. Optimal Spindle Head : The spindle head is designed with the optimal rectangular structure ratio (1:1.25) permitting Z-axis to achieve the best machining rigidity. The interior of the spindle head is properly spaced combined with circular rib reinforcement, which significantly upgrades cutting rigidity and stability. Outstanding Z-axis Balancing System : Designed with two-direction balancing circuit combined with two hydraulic counter-balance cylinders, the transmission mechanism of the balancing system is firmly fastened to the Z-axis. This special design ensures accurate response on Z-axis servo motor and meets the requirement of high thrust force. Outstanding Feed System : The X, Y, Z-axis are mounted with high precision P-class linear guideways featuring 0.003~0.005 extra low friction co-efficiency, minimum sticking and high moving sensitivity. This also results in higher accuracy. Outstanding Feed System Construction : Three axes feeds are transmitted through class C3 precision ball screws, pretensioned at both ends to reduce screw thermal displacement to a minimum. The entire machine employs absolute coordinate system to eliminate complexity of structure. Both ends of ball screw are provided with colliding protection devices. Extra Powerful Cutting Capability : The BT50 spindle has a diameter of Ø100 mm and is supported by class D4 angular contact ball bearings. Maximum spindle speed is 6,000 rpm. The powerful spindle motor provides great torque output combined with the use of 1:4 ZF-2K 250 gearbox with high / low speed ranges. This powerful drive system provides sufficient horsepower and torque output to suit various machining conditions.

DV series with Fixed Column

CLOSED LOOP BALANCING SYSTEM The spindle head movement on Z-axis is counter-balanced by a nitrogen gas balancing system with two cylinders. This balancing system provides an automatic balance between the air cylinders and the spindle head, enabling the spindle to move smoothly without vibration. Incase of power failure, the spindle head does not slip down, in order to protecting the safety of tool and workpiece.

RIGID LINEAR WAYS The 3 axes are mounted with HGH (X,Y) and RGH (Z) Linear guideways, featuring constant loads at 4 directions and automatic centering, and exhibit many outstanding features, such as high accuracy, high speed high rigidity, high loading resistance and low friction. With these special features, you get higher dynamic accuracy, smooth cutting, energy saving and high cutting efficiency.

PRECISION SPINDLE The spindle runs in class P4 precision angular contact ball bearings, and is transmitted through a two-step ZF gearbox. The outside of the spindle is cooled by circulated oil cooler to prevent spindle displacement during running.

TWO-STEP ZF GEARBOX The spindle rotation is transmitted through a German ZF-DUOPLAN 2K 250 INLINE two-step gearbox. The outstanding gearbox provides high torque output, high efficiency, low noise and fully enclosed oil bath lubrication. The gearbox is cooled by an oil cooler to extend its service life.
