gantry machining center

There are many types of machining centers. Gantry machining center is one of them. It refers to a machining center in which the axis of the Z axis of the main shaft is perpendicular to the worktable. The overall structure is a portal structure frame composed of double columns and top beams. There are also beams between them.

What does a gantry machining center consist of?

The gantry machining center consists of a worktable, a gantry, a ram, a tool magazine, an accessory head library and a numerical control system, including fixed beam type (beam fixed, worktable moving or rotating), moving beam type (beam moving up and down, worktable moving back and forth), moving column type (fixed table, moving gantry), crane type (fixed table, moving beam), etc., it is mainly suitable for processing large workpieces and workpieces with complex shapes.

What are the characteristics of the gantry machining center？

1. The gantry body adopts the original three-dimensional variable diameter structure design. After the finite element analysis, the structure of the body is optimized to a large extent, ensuring the stability and reliability of the body, and preventing the deformation of the body, thereby improving the service life of the machine tool.
2. The gantry base is designed with honeycomb staggered reinforcing ribs, and the width of the base of all gantry machine tools is kept the same as the width of the worktable, making the structure more stable.
3. The gantry column adopts a 45°impact resistance design, and the connection part between the column and the base adopts a 45° oblique span, which not only increases the connection strength between the base and the column, but also increases the rigidity of the machine tool during strong cutting.
4. The gantry workbench adopts the "beehive type" to increase the thickness of the workbench, increase the rigidity of the workbench, and increase the bearing capacity and stability.
5. The gantry sliding seat is designed with a 45°stepped ramp. The linear guide rails for bearing and guiding are arranged asymmetrically to make the division of labor different, which greatly reduces the influence of the Z-axis weight on the gantry beam and improves the accuracy of the entire Y-axis.

What is the difference between gantry machining center and ordinary machining center?

The gantry machining center is a vertical machining center. Compared with the ordinary machining center, the difference is mainly reflected in:

1. Structure. The X-axis of the gantry machining center is very long and has a double-column structure. The stroke of the Y-axis is larger than that of the ordinary machining center, and it also has one more side milling head than the ordinary machining center;
2. Processing range. Because the gantry machining center is supported by double columns, it has obvious advantages in heavy cutting, so the workpieces that can be processed are relatively large, and some larger or more complex workpieces can only be processed by the gantry machining center, which cannot be processed by ordinary machining centers;
3. Dimensions. Gantry machining centers are usually larger than ordinary machining centers.

What are the uses of the gantry machining center?

It is mainly used in heavy industries, such as aircraft, automobiles, ships, etc., and mainly processes large and complex workpieces, such as beams, frames and certain parts of large machinery for processing aircraft. All in all, the gantry machining center is a large-scale machine tool designed for processing large and complex parts, which is suitable for various industries, especially the large-scale parts industry.
