1)Table surface and c-axis center at the same level, to improve the accuracy of machining datum point (program reference point).
2)Table can be reserved 2 holes (OPT) with 6-8 bars to install jigs.
3)4/5 axis rotary table adopts two section worm shaft and worm wheel.
4)To connect the base of 4/5 axis with X axis linear way and ballscrew can makes the interference of Z axis travel decrease effectively to maintain high rigidity of machine.
