The difference between vertical machining center and gantry machining center

What is the difference between a vertical machining center and a gantry machining center? Longmen machining centers and vertical machining centers are relatively common machining centers. What are the differences in their structure? Many people don’t know much about these two machining centers. Today we will take you to understand vertical machining centers and gantry machining. The difference in the center.

     The vertical machining center refers to the machining center of the spindle shaft and the vertical sleeve of the worktable. It is mainly suitable for processing plates, plates, molds and complex parts of small shells. The vertical machining center can complete processes such as milling, boring, drilling, tapping, and thread cutting. The vertical machining center has at least three axes and two connecting rods, and generally three axes and three connecting rods can be realized. Some can be controlled by five-axis and six-axis. The column height of the vertical machining center is limited, and the processing scale of box-like workpieces should be reduced. This is the shortcoming of the vertical machining center. However, the vertical machining center workpiece clamping and positioning are convenient; the tool movement track is easy to investigate, and the debugging program is easy to check and measure. If problems are found in time, it can be stopped or modified. The cooling conditions are easy to establish, and the cutting fluid can directly reach the tool and the processing surface; the three-coordinate axis is consistent with the Cartesian coordinate system, which feels intuitive and consistent with the drawing perspective. The chip is easy to remove and drop to avoid scratching the processing surface. Compared with the corresponding horizontal machining center, the structure is simple and the floor space is small.

     Gantry machining center refers to the spindle axis and vertical table cover machining center. It is mainly suitable for the processing of large parts, including fixed beams, moving beams, moving columns, bridge type five-axis linkage and high-speed machining and other different styles of functions and applications. Can make different choices according to product processing needs. Gantry machining center has fixed beam type (fixed beam, turntable), movable beam type (up and down, mobile platform), mobile column type (fixed platform, gantry mobile), bridge type (fixed platform, movable beam), and there are also the above composite forms Longmen processing centers have different processing characteristics, capabilities, and product processing purposes.

     The support structure of the gantry machining center is different from that of the vertical machining center: the gantry machining center refers to the spindle axis and the vertical table cover machining center. The support structure of the Z axis of the gantry is different. Between the two rows of the Y axis, the load of the worktable is increased. Scale: Vertical machining center refers to the combination of spindle axis and vertical table cover machining center, straight X axis and Y axis, Z axis is used to move the column up and down, suitable for small precision molds and parts processing. The slightly larger straight plus about 4 meters can determine the model based on specific data processing.

     The gantry machining center is different from the vertical machining center: the gantry machining center is mainly suitable for the processing of large parts. The vertical machining center is mainly suitable for the processing of plates, plates, molds and parts of the small shell complex, but the small gantry machining center can replace the large vertical machining center, and the large vertical machining center clamps the workpiece in the small gantry machining center Convenient, and the cost is much higher than that of a small gantry machining center.
