CNC gantry machining center is a high-precision and high-efficiency automatic equipment, which can realize the processing of multiple processes through one clamping of the workpiece, effectively avoid the error of multiple clamping and tool setting, and also improve the processing efficiency. The higher the precision of the CNC gantry machining center, the more strict the requirements for installation environment, temperature, humidity and vibration, which need to be considered. Let's briefly discuss the requirements for the installation foundation of the CNC gantry machining center.
The foundation for installing the gantry must be firm and made according to the specific foundation drawing issued by the manufacturer. For the ground with relatively tight concrete, if it is thick enough, the foundation bolts can be directly installed according to the drawing. For the ground with relatively loose foundation, it must be re excavated according to the foundation drawing. Concrete with sufficient thickness shall be poured to prevent the gantry machining center from sinking in the later stage, and the bed will be deformed after falling, so there will be no accuracy. The size of the foundation shall not be less than the overall size of the support area of the gantry machining center, and the construction thickness of the foundation concrete must be in accordance with the national standard.
Gantry machining centers are prone to vibration when machining large workpieces. The heavier the gantry processing center, the thicker the foundation will be. The low-pressure strength of concrete is 1800 n / m2, the tensile strength is 180 n / m2, and the bearing strength of the ground is more than 5 tons / m2. The finished concrete foundation can't have cracks, and shockproof materials should be added in the foundation workshop.
