G Series Gantry Machining Center (hard guide)
Machine Summary:
G series gantry machining center adopts the closed gantry frame structure consisting of bed ,column and beam ,with features of high rididity 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.
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 and stability of the machine tool.
Three axes are all equipped with the sliding guide treated by the high-frequency quenching to enhance the whole bearing capacity and durability.
Structure and performance
1. Apply the computer-aided engineering (CAE)system to finish the optimized structure design and enhance the reliability 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.
2. The surface of hard guide is treated by the high frequency quenching and the hardness can reach HRC 45°,with the higher cutting propety.
3. Apply two-times aging treatment for the cast to guarantee the complete release of internal stress and the precision persistence of the machine tool.
4. X-axis can adopt the constant flow static-pressure guide optionally with the high bearing capacity ,strong abilities of shock proof and shock absorption,good precision stability and long service life.
5. 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.
6. The addition of supporting mechanism on 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 reliability of precision during the processing.
7. The transmission mechanism with the large loading adopts the precision planet gear box characterized by the large tansmission torque ,high efficiency and precision.All servo axes are driven by spring coupling with good rigidity and accurate travel.
8. The beam adopts the composite structure of rectangle up and down stage solid guide and rolling guide to neutralize the disturbing moment casued by the offset of center of gravity of spindle box's boring and milling head and traverse slide .Y-axis traverse slide,transverse guide and slide wedge all adopt the filming treatment to enhance the precision and service life.
9. X-axis can adopt the constant flow static pressure guide optionally with the high bearing capacity,strong abilities of shock proof and shock absorption,good precision stability and long service life.
10. The precision assembly of spindle in the constant temperature,dust-free and closed envieonment can guarante the assembly precision.
11. 3-axis bearing seat is scraped precisely without the gasket design to guarantee the smoothness of 3-axis transmission.
12. The assembly of joint surface adopts the technique of glue injection,which can greatly increasel.
13. 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.
14. The large type adopts the hanging-type operation box that can be rotatable to the table sufae and convenient for users' operation.
15. Hydraulic balancing system can guarantee the smooth operation of Z-axis.
16. It leaves the mounting surface of tool magazine to add the tool magazine quickly later.
