Gantry-type Machining Center

Heavy cutting Performance,wide column design to ensure high stability

Machine feature:

•The V shap base with a strong internal structure design,to ensure high loading capacity and positioning accureacy

•Column and crossbeam is a whole structure to strengthen machine rigidity which can avoid vibration during cutting

•Boxway on Z axis ensure high rigidity

•Main frame is made of GB300 casting for superior rigidity

•Oil and coolant separation system to avoid the cutting liquid get mixed with the lubrication oil

•Extra wide column to ncrease the connection surface with the crossbeam which can avoid vibration during cutting

•Perfect lubrication system,to ensure automatic lubrication for every movable parts at regular time and fixed quantity

•Hardend and ground C3 Doubel Nut screw are pre-tensioned to minimize backlash,provide high precision movement,and reduce heat-deformation on all axes

•High quality magnetic brake on Z axis to ensure reliability

•4 versus 4 NSK high precision slant beraing design for each axis improve stability greatly
