GANTRY TYPE MACHINING CENTER GMC1120

GMC1120 Gantry machining center

1.Machine introduction

The machine’s frame structure matching with grinding slide guide makes the machine with high rigidity,strong shock absorption, wide processing range, high stability. The machine has kinds of processing functions, such as milling,boring,drilling,tapping etc.It can be equipped with various milling heads, and has the function of changing head manually,enlarging machine’s processing range, and can finish the processing of multiple processes simultaneously in single clamping. 

2 Machine main features and characteristics£º

 1. Machine main parts include: base,table,column,beam,slider,ram,pneumatic

   system,lubrication system,cooling,safe guard,guide way guard,CNC system,

electric control,tool magazine etc.The bed is box structure design with high stability and rigidity.And bed,column,beam and table adopt high grade castings which are made aging treatment with good rigidity, stable accuracy,durable in use. 

2.X axis£ºthe workable adopts double-layer reinforcing rib and hollow antivibration structure which improve the stability of processing. The table moves along with heavy duty linear roller guide way of bed, X driver adopts AC servo motor driving ball screw rotation to carry out longitudinal movement of table.X axis adopts heavy duty linear roller guide way,it has fast response and strong carrying capacity. 

3.The integrated frame adopt large section tubular structure, inside it adopts “sun shaped rice word”rib layout structure, this makes it with the characteristic of high bend resistance and anti twist. Y axis: adopts two heavy duty linear roller guide ways orthogonal to each other and combines with one rectangular guide way, it forms a unique structure of “linear-box combination” with good rigidity and quick response;Y axis driver adopts AC servo motor  driving ball screw rotation to carry out cross movement of slider along crossbeam. Y axis has good shock absorption performance and ensure the stability of cutting.  

4. Z axis: adopts rectangular hard rail structure with six sides grinding, and is scraped by hand,it can not only ensure the accuracy of guide way, but also increase the life of guide way greatly;Z axis driver adopts AC servo motor reducing speed 1:2 by synchronous belt,driving the rotation of ball screw to carry out vertical movement of ram along the slider. 

5.X/Y/Z lead screws are all high precision ball screws with optimized pretension force.

6.The milling head is equipped with spindle rotation detecting system, which can realize automatic positioning of spindle and has tapping function.
