1 Workbench

The workbench of the gantry machining center is basically rectangular. Large castings such as workbenches, bed bodies, columns, crossbeams, and sleepers are made of Mihanna cast iron. The inner cavity of the castings is a honeycomb composite arrangement structure, with advanced design and all have undergone aging and secondary tempering treatment to eliminate residual internal stress and stabilize the material, ensuring the stability of workpiece processing accuracy and machine bed life.

2 Gantry

The gantry is composed of a crossbeam and two columns. It can be divided into three types: fixed crossbeam, segmented lifting of crossbeam locked by positioning blocks, and arbitrary lifting of crossbeam.

3 ram

The ram can be divided into two types structurally: open and closed. The open structure of the ram is clamped onto the spindle box through a pressure plate, resulting in a large cross-sectional area of the ram; The closed structure of the ram is clamped in the spindle box, and the cross-sectional area of the ram is small.

4 tool magazine

There are three basic types of tool libraries: turret type, drum type, and chain length type.

5 Attachment Headstock

The processing of large and complex parts usually requires many attachment heads. The attachment head is specially designed according to the processing requirements of the workpiece, generally divided into right angle head, extended head, special angle head, and universal head.

6 CNC system

The CNC system generally adopts SINUMERIK840C and 840D from German SIEMENS company or 31I series from Japanese FANUC company, and the CNC axis adopts full closed-loop control.

7 Precision

The accuracy of a machine tool refers to its original accuracy without being subjected to external loads. Accuracy is usually represented by its opposite - the deviation from the ideal state (referred to as error), and the smaller the error, the higher the accuracy.
