GY Series Gantry Machining Center (Linear Guide) 
Machine Summary:

    GY  series gantry machining center adopts the closed gantry frame strucutre consisiting to bed ,column and beam, with features of high rigidity and high stability.The machine tool can finish the processing of milling ,boring ,drilling,tapping and sinking.It is mainly designed for the processing 
of automobile sheet metal mold, plastic mold ,precision machinery parts and aerospace and shipbuilding.Equipped with the accessory milling head, it can realize the five-face processing at one time of clamping ,serving several purposes.It can effectively enhance the processing precision and 
processing efficiency.
Structure and Performance:

1.The integrated casting of column and beam can reduce the binding site to provide more guarantee for the stability of YZ axes.(Suitable for series type with the portal width of 1.2and 1.8m).
2.Apply the computer-aided engineering (CAE) system to finish the optimized structure design and enhance the reliabilit of machine tool ,and the finite element method (FEM) to take the scientific analysis and optimization of design structure,which can guarantee the rigidity and stability of the whole machine structure.
3.X-axis with portal width over 2.8m adopts the design of 4-linear guide.It can provide more balanced supporting points for the table and thus guarantee that the table can keep its shape during the nominal loading.
4.The integrated casting of machine tool base with the travel of 6m and less can reduce the binding face to guarantee the rigidity and precision stability.
5.The surface of hand guide is treated by the high frequency quenching and the hardness can reach HRC 45,with the higher cutting propety.

6.Apply two-times aging treatment for the cast to guarantee the complete release of internal stress and the precision persistence of the machine tool.
7.The casting of the machine tool is made of high strength inoculated cast iron and high quality resin bonded sand,which is treated by multiple aging techniques to ensure the rigidity abd stability of the machine tool.X-axis adopts the imported high-precision linear rolling guide to meet the high-precision and high-efficiency processing.
8.The addition of supporting mechanism on the screw with the travel over 4m can effectively avoid the falling caused by the deadweight due to the overlength of screw and thus prolong its service life and reliabolity of precision during the processing.
9.The transmission mechanism with the large loading adopts the precision planet gear box characterized by the large transmission torque,high efficiency and precision.All servo axes are driven by spring coupling with good rigidity and accurate travel.
10.It can be equipped with the slope beam design to effectively resolve the cast gravity and work-piece cutting force.

11.The heavy-duty linear guide is characterized by the fast speed ,high precision and strong bearing capacity.
12.The standard gear-type spindle with the portal width of 2.8m and over can realize the high-torque heavy cutting.
13.The precision assembly of spindle in the constant temperature,dust-free and closed environment can guarantee the assembly precision.
14.3-axis bearing seat is scraped precisely without the gasket design to guarantee the smoothness of 3-axis transmission.
15.The foot treadle (optional)and moving foot-operated switch (optional)are convenient for users to get up and down the machine tool to change the tool.

16.The large type adopts the hanging-type operation box that can be rotatable to the table surface and convenient for users' operation.
17.Hydraulic balancing system can guarantee the smooth operation of Z-axis.
18.It leaves the mounting surface of tool magazine to add the tool magazine quickly later.
