What's the difference between a gantry machining center and a common machining center?

Gantry machining center is the machining center whose axis of Z axis is perpendicular to the worktable. It consists of a workbench, a gantry, a ram, a tool magazine, an accessory head magazine and a numerical control system. Mainly used for processing large workpieces and workpieces with complex shapes. Compared with ordinary machining centers, it is mainly different in structure, machining range and size. Gantry machining centers are generally three-axis, and four-axis and five-axis gantry machining centers are also used when machining requirements are high. Let's look at the difference between a gantry machining center and a common machining center. 1. What machinery is the gantry machining center?

There are many kinds of machining centers, and the gantry machining center is one of them. It means that the axis of the spindle Z axis is perpendicular to the machining center of the workbench. The whole structure is a portal structure frame composed of double columns and top beams, and there are beams in the middle of the double columns.

The gantry machining center consists of workbench, gantry, ram, tool magazine, accessory head magazine and numerical control system. There are fixed beam type (beam is fixed, table moves or rotates), moving beam type (beam moves up and down, table moves back and forth), moving column type (table is fixed, gantry moves), crown block type (table is fixed, beam moves) and so on. It is mainly suitable for processing large workpieces and workpieces with complex shapes.

2. What's the difference between a gantry machining center and a common machining center?

Gantry machining center belongs to vertical machining center. Compared with ordinary machining centers, the differences are mainly reflected in:

1. Structurally, the X axis of the gantry machining center is very long, and it is a double-column structure. The Y-axis stroke is larger than that of a common machining center, and there is an additional side milling head.

2. From the processing scope, the gantry machining center has obvious advantages in heavy cutting because of the support of double columns, so the workpieces that can be processed are relatively large, and some relatively large or complex workpieces can only be processed by the gantry machining center, which cannot be processed by ordinary machining centers.

3. In terms of size, the gantry machining center is usually larger than the ordinary machining center.

3. How many axes is the gantry machining center?

There are three axes, four axes and five axes.

Gantry machining center is a CNC lathe. Generally, it is a three-axis gantry machining center with X, Y and Z axes, but some gantry machining centers are four-axis, and a rotating shaft is added on the basis of the three axes to complete the four-sided machining of the workpiece. Some with high machining requirements will also use the five-axis gantry machining center, add a rotating shaft and a pendulum shaft, and cooperate with the five-axis numerical control system to machine complex spatial surfaces with high precision.
