1. Worktable: The worktable of a gantry machining center is basically rectangular. Large castings such as the worktable, bed, columns, crossbeam, and ram are made of cast iron or welded components. The internal cavities of the castings feature a honeycomb composite arrangement structure, an advanced design, and all undergo aging and secondary tempering treatments to eliminate residual internal stress, stabilize the material, and ensure stable workpiece machining accuracy and machine tool life.
2. Gantry: The gantry consists of one crossbeam and two columns. It is divided into three types: fixed crossbeam, crossbeam locked by positioning blocks with segmented lifting, and arbitrary crossbeam lifting.
3. Ram: Structurally, the ram can be divided into open and closed types. Open rams are clamped to the spindle box by pressure plates and have a large cross-sectional area; closed rams are clamped inside the spindle box and have a small cross-sectional area.
4. Tool Magazine: The basic types of tool magazines are turret type, drum type, and chain type.
5. Attachment Head Library: Machining large and complex parts typically requires numerous attachment heads. These heads are specially designed according to the workpiece's machining requirements and are generally categorized as right-angle heads, extended heads, special-angle heads, and universal heads.
6. CNC System: There are many CNC system suppliers; different brands and models are available depending on the specific needs.
7. Accuracy: The accuracy of a machine tool refers to its original accuracy under unloaded conditions. Accuracy is usually expressed as its opposite-the deviation from the ideal state (referred to as error). The smaller the error, the higher the accuracy.
