The gantry machining center refers to a machining center where the axis of the spindle is perpendicular to the worktable. The overall structure is a portal frame, consisting of double uprights and top beams, with a beam in the middle. Gantry grinding machining center is suitable for processing large workpieces and complex shaped workpieces.

1 Workbench

The worktable of the gantry machining center is basically rectangular. Large castings such as workbench, bed, column, beam and ram are made of cast iron or welded parts. The inner cavity of the casting is a honeycomb composite arrangement structure. The design is advanced, and it is subjected to aging and secondary tempering treatment to eliminate residual internal stress and stabilize the material. , To ensure the stability of cnc machining parts accuracy and machine tool life.

2 Dragon Gate

The dragon gate is composed of a beam and two uprights. It can be divided into three types: fixed beam, fixed beam lifting by positioning block, and free lifting of beam.

3 Ram

Ram can be divided into two types: open and closed. The ram with an open structure is clamped on the spindle box by a pressure plate, and the cross-sectional area of ​​the ram is large; the ram with a closed structure is clamped in the spindle box and the cross-sectional area of ​​the ram is small.

4 Tool magazine

The basic types of  tool magazine include turret type, drum type and chain length type.

5 Accessory header library

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, and is generally divided into a right angle head, an elongated head, a special angle head and a universal head.

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 precision of the machine tool refers to the original accuracy of the machine tool under the condition of no external load. Accuracy is usually expressed by its reverse side-deviation from the ideal state (abbreviation error). The smaller the error, the higher the accuracy.
