A gantry milling machine, referred to as a gantry milling machine, is a milling machine with a portal frame and a long horizontal bed. The gantry milling machine can use multiple milling cutters to machine the surface at the same time, and the machining accuracy and production efficiency are relatively high. It is suitable for machining the flat and inclined surfaces of large workpieces in batch and mass production. CNC gantry milling machines can also process space curved surfaces and some special parts.

American Whitney created a horizontal milling machine in 1818; to mill the spiral groove of a twist drill, American Brown created the first universal milling machine in 1862, which is the prototype of a lifting table milling machine; it appeared around 1884. Gantry milling machine; semi-automatic milling machines appeared in the 1920s, and the worktable can use the stopper to complete the automatic conversion of "feed-fast" or "fast-feed".

How to carry out the accurate inspection of the gantry milling machine?

If the user buys this machine tool, it is mainly used to perform finishing on the workpiece. A wire or half wire or even smaller, the accuracy of the gantry milling machine is the main core issue.

When rough machining is performed on the blank, it should be checked how much the force of the machine tool is, that is, what is the maximum feed amount at one time. Because his machining of the blank is rough, the requirements for accuracy are not too high, but the requirements for efficiency are very high, so he requires this machine tool to be powerful and the amount of cutting tools to be large. Of course, the strength of the gantry milling machine mainly depends on the engine, but there is still an important point that cannot be ignored, that is, the screw. If it is faster and the amount of knife is larger, then the screw is likely to deform or even break. Therefore, in this case, the bearing capacity of the screw should also be considered. Feeling the user's concern should have nothing to do with the parts he is processing. If the user buys this machine tool, the important purpose is to process the blank.

Nowadays, the use of machine tools has become very popular, but for a series of high-precision machine tools such as the newly launched gantry milling machine in recent years, the daily maintenance work has been neglected by people. Some faults of the gantry milling machine can be avoided during maintenance. In the use of gantry milling machines, formulate rules and regulations for the daily maintenance of CNC machine tools. Always check the grid voltage used by the CNC machine. After 5 minutes of booting, check that everything is normal, and then it can be used normally.

Turn on the automatic lubrication system normally. Check the guide rail protection and wipe the oil in time.

Shut down the machine should clean the dirt in time. Rub oil on the guide rails and the workbench in time. Turn off the power in time. The above are some details that should be paid attention to in the daily use process. Only after paying attention to and maintaining the details can the working efficiency and working accuracy of the gantry milling machine be ensured.
