What are the factors that affect the machining accuracy of the gantry machining center?
The structure of the gantry machining center is very different from the traditional machining center equipment with a similar stroke. Generally, the X-axis stroke is more than 2 meters. It is recommended that the user use a CNC gantry. First of all, workpieces above 2M are generally relatively large. The rigidity and stability of the machine tool must be guaranteed to ensure the machining accuracy and the service life of the gantry machining center machine tool. In addition, from the perspective of processing stability, cost, machine practicability, and use status of the machining center, it is generally 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, and the accuracy and machine rigidity are more guaranteed. The overhang of the machining box of the gantry machining center is shorter than that of the C-shaped steel, which ensures that the original precision of the gantry-shaped machining center is higher than that of the C-shaped steel, and can be used for a long time.
What are the factors that affect the machining accuracy of the gantry machining center?
1. Screw vacancy of 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 very important. If there is no machine with a constant temperature working environment, the machine needs to be idling before processing every day to match the machine temperature with the outside temperature. During the processing of the gantry machining center, it is necessary to check the reverse space of the screw frequently.
2. 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 should be checked and adjusted regularly. At present, the machine tools are mainly castings, and horizontal adjustment is also one of the means to prevent the deformation of the gantry machining center.
3. Machine tool spindle and machining tool: The key to the taper hole of the gantry machining center is the tool. Taper and taper accuracy are key steps to ensure machining accuracy. In addition, the quality of the machining tool of the CNC gantry machining center directly affects the machining accuracy. The service life of the machining tool determines the machining accuracy of the machining center. In addition, many gantry machining center users do not pay much attention to cutting fluid. They feel they just need to cool the tool. However, it is not the cutting fluid that plays the role of lubrication and cooling, which is very important for the machining process of the gantry machining center.
How to Improve Machining Accuracy and Efficiency of Longmen Machining Center ？
What is the machining accuracy of the gantry machining center? To briefly explain this concept, accuracy refers to the difference between the actual measured value and the measured value of the machining center machine tool system. If the difference between the two is extremely small, then the measurement is highly accurate.
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. Skillfully use the internal program, reduce the cumulative error of the CNC system, and use the flexibility of the main program and subroutine. In the process of complex mold processing, multi-piece processing is usually used. If there are several identical shapes, the relationship between the main program and the subroutine should be used, and the subroutine should be used repeatedly in the main program until the processing is completed, so as to ensure the consistency of the processing size and improve the processing efficiency.
The article mainly introduces the factors that affect the machining accuracy of the gantry machining center. After browsing the article, you can understand that the structure of the gantry machining center equipment is more stable. Its gantry-type double-column structure is stronger and more stable than the C-type single-column structure. Rigidity is more guaranteed. The overhang of the processing box of the gantry machining center is shorter than that of the C-shaped steel, which ensures that the original precision of the gantry-type machining center is higher than that of the C-shaped steel, and can be used for a long time.
