Longmen milling and Longmen machining center

There are two types of gantry milling machines: ordinary gantry milling machines and CNC gantry milling machines. I won't mention ordinary ones, which usually have poor accuracy and low efficiency. However, with the configuration of side milling heads, for some special purpose workpieces, there can be high processing efficiency! The biggest difference between CNC gantry milling machines and gantry machining centers is that the former does not have a tool magazine, while the latter is equipped with a tool magazine. In this way, the latter can automatically change the tool during processing. In theory, the precision of machining centers should be higher than that of milling machines, but now everyone has blurred this concept. Anyway, ISO230 or VDA standards are used for precision acceptance.
