Main structural features:

(a) The rotary bearing adopts double cylinder roller bearing which is high in rigidity and accuracy.

The center unload device (which positioned at the upside of the bearing) enhances the rotation accuracy, rigidity and strength of the table.

(b) The table guideways of linear motion and rotation are both adopt compound guideways

(sliding guideways with plastic inserts combined with guideways with rollers). They are of high contact rigidity, low friction, wear resistant,

high damping capability, and low high-frequency vibration. They are also of high accuracy, self-lubrication, and easy maintenance.

(c) The linear motion feeding mechanism of table adopts backlash elimination device and preload ball screw for feeding drive;

the rotary motion feeding mechanism, adopts double preload pinions and girth gear devices, which can eliminate backlash automatically

and ensure high drive accuracy. Each feeding drive mechanism is of good structure, high accuracy, and ensures drive parts stable.

(d) Feeding mechanism is driven by the SEW Germany servo-motor, equipped with Heidenhain measuring system for

longitudinal and rotary motions.

(e) Uses separate electric cabinet, PLC controlled, DRO device Heidenhain, uses independent hydraulic station to control clamping

for each motion axes, and electric Hand wheel for micro-feeding.
