The structure of the gantry machining center is very different from traditional machining center equipment with similar stroke. Generally, the X-axis stroke is more than 2 meters, and it is recommended that users use a CNC gantry. Firstly, workpieces above 2M are generally larger. The rigidity and stability of the machine tool must be ensured to ensure machining accuracy and the service life of the gantry machining center machine tool. In addition, from the perspective of machining stability, cost, practicality of the machine, and usage status, it is generally more recommended to choose the gantry type.
The structure of the gantry machining center equipment is more stable, and its gantry type double column structure is stronger and more stable than the C-type single column structure, ensuring better accuracy and machine rigidity. The suspension distance of the machining box on the gantry machining center is shorter than that of C-shaped steel, ensuring that the original accuracy of the machining on the gantry machining center is higher than that of C-shaped steel and can be used for a longer period of time.
What are the factors that affect the machining accuracy of the gantry machining center
Screw vacancy in gantry machining center: The positioning accuracy of gantry machining center directly affects the machining accuracy of the workpiece, and the influence of temperature on positioning accuracy is crucial. If there is no machine with a constant temperature working environment, it is necessary to let the machine idle before processing every day to match the machine temperature with the external temperature. During the machining of the gantry machining center, it is necessary to regularly check the reverse clearance of the screw.

Machine horizontal position: The level of the gantry machining center is also a key aspect that affects the machining accuracy of the gantry machining center. Therefore, the gantry machining center needs to undergo regular inspections and adjustments. At present, machine tools are mainly castings, and horizontal adjustment is also one of the means to prevent deformation of the gantry machining center.
Machine tool spindle and machining tool: The key to the tapered hole in the gantry machining center is the tool. The accuracy of taper and taper is a key step in ensuring machining accuracy. In addition, the quality of the cutting tools used in CNC gantry machining centers directly affects the machining accuracy. The service life of machining tools determines the machining accuracy of machining centers. In addition, many users of gantry machining centers do not pay high attention to cutting fluids. They feel that only cooling tools are needed. However, it is not the cutting fluid that plays a role in lubrication and cooling, which is very important for the machining process of gantry machining centers.
How to improve the machining accuracy and efficiency of gantry machining centers
What is the machining accuracy of a gantry machining center? Simply explain this concept, precision refers to the difference between the actual measurement value and the measurement value of the machining center machine tool system. If the difference between the two is minimal, then the accuracy of the measurement is high.
The CNC programming of the gantry machining center is the basic working step of its machining. An experienced programmer knows how to write good programs. Cleverly using intrinsic programs to reduce cumulative errors in CNC systems, and utilizing the flexibility of the main program and subroutines. In complex mold processing, multi piece machining is usually used. If there are several identical shapes, the relationship between the main program and subroutines should be utilized, and the subroutines should be repeatedly used in the main program until the machining is completed, in order to ensure the consistency of machining dimensions and improve machining efficiency
Gantry machining center processing
Incremental calculation, also known as incremental calculation, is a software feature that whenever a piece of data changes, the gantry machining center attempts to save time by recalculating only those outputs that depend on the changing data. Incremental calculation is commonly used to write programs, but continuous execution of multiple programs in gantry machining centers can result in accumulated errors. Now we are trying to use absolute calculation to write programs, which can reduce the cumulative error of the CNC system and ensure machining accuracy.
The article mainly introduces the factors that affect the machining accuracy of gantry machining centers. By browsing the article, you can learn that the structure of gantry machining center equipment is more stable. Its gantry double column structure is more sturdy and stable than the C-type single column structure, and accuracy and machine rigidity are more guaranteed. The suspension distance of the machining box on the gantry machining center is shorter than that of C-shaped steel, ensuring that the original accuracy of the machining on the gantry machining center is higher than that of C-shaped steel and can be used for a longer period of time.
