Gantry CNC Milling Machine
Product details:

1.Extremely rigid and stable structure, the oversized column combined with box type beam construction features additional machine rigidity.

2.The slant beam construction with increased slide way surfaces efficiently upgrades force distribution area this results in greater stability.

3.The spindle head is located at the center of beam, providing high movement accuracy, superior heavy cutting capability and outstanding rigidity. The position is specially designed with symmetrical to center.

4.Equipped with spindle motor ball screw and double counter-balance cylinders are all properly located at the best positions to avoid unequal torque, while assuring the best structural accuracy.

5.The double counter – balancing cylinders on Z-axis are suspension supported, close to the movement gravity center, symmetrical to the spindle drive ball screw and the center of spindle motor. Optional position design not only fully eliminates the possibility of unequal torque, but also provides high feeding accuracy and machining accuracy.

6.Linear ways on X/Y-axis combined with box ways on Z axis.

Two kind of Spindle as optional:

A.Short nose type ( for universal machining)

B.Long nose type ( for deep cavity machining)
