To prevent the column from thermal deformation due to temperature growth and affection on the cutting accuracy due to the structural rigidity, the column is designed with a symmetrical and double-wall structure.
The base is rib reinforced for effective vibration dampening during machining, resulting in superior stability of cutting.
The spindle is a short nose design to exhibit exceptional rigidity. The spindle head is designed by Finite Element Analysis to achieve an optimal structure with increased length of locking surface, making it possible for deep hole machining.
Chips fall down by self-weight into the chip augers at both sides of the base, then chips are delivered to the screw type chip conveyor in the coolant tank. This design efficiently remove chips and heat out of the machine, hence ensuring machining accuracy at all times.

The coolant jets around spindle device employs 4 coolant nozzles around the spindle, that provides the best cooling effect to the tool and the workpiece resulting in better machining quality.
The rotary table is driven by a servo system.
Employ the three-piece clutch (±5" accuracy) to ensure positioning accuracy.
Low-noise: The design of return unit can absorbs the voice which comes from steels balls’ impact, then greatly reduce the noise.
High acceleration/deceleration velocity: the special route unit and strength design can reduce the impact force from steel balls’. Therefore, it can sustain the operating environment of high Dm-N value and high acceleration/deceleration velocities.
Roller type linear ways on all three axes provide better dynamic rating load compared with its class of roller type linear way. This feature not only ensures the entire machine accuracy, but also provides the highest rigidity as well as outstanding cutting performance.
The linear motion guide features minimum wear and extra long lifespan.
Especially ideal for high speed movement and dramatically reduce the power requirement of machine.
