Structural features of gantry machining center

1. Workbench
The workbench of a gantry machining center is basically rectangular. Large castings such as worktables, lathes, columns, beams and rams are made of cast iron or welded parts. The inner cavity of the castings is a honeycomb composite arrangement structure with advanced design. They are all processed by aging and secondary tempering to eliminate residual internal stress and make the material stable. , ensuring the stability of workpiece processing accuracy and machine tool life.
2. Gantry
The gantry consists of a beam and two columns. It is divided into three types: fixed beam, segmented lifting of the beam locked by positioning blocks, and arbitrary lifting of the beam.
3. Ram
Rams can be divided into two types: open type and closed type. The ram of the open structure is clamped on the main spindle box through the pressure plate, and the cross-sectional area of the ram is large; the ram of the closed structure is clamped in the main spindle box, and the cross-sectional area of the ram is small.
4. Tool magazine
There are three basic types of tool magazines: turret type, drum type and chain length type.
5. Attachment header library
The machining of large, complex parts often requires many attachment heads. The attachment head is specially designed according to the processing requirements of the workpiece, and is generally divided into right-angle heads, extended heads, special angle heads, and universal heads.
6. CNC system
There are many CNC system suppliers, and there are different choices of system brands and models according to different needs.
7. Accuracy
The accuracy of a machine tool refers to the original accuracy of the machine tool without external loads. Accuracy is usually expressed by its opposite - the deviation from the ideal state (referred to as error). The smaller the error, the higher the accuracy.
