Description

Technical Field

[0001] The utility model relates to the technical field of gantry milling machines, in particular to a numerically controlled gantry tent milling machine. Background Art

[0002] A gantry milling machine is a large metal processing machine tool used for milling workpieces. It is named after its structural shape, which is similar to a gantry with beams and columns supporting the worktable. Gantry milling machines are usually used to process large workpieces, such as ship components, wind power equipment, railway vehicle parts, etc.

[0003] Most of the existing gantry milling machines are hard rail gantry milling machines. Long-term use will cause the milling machine processing accuracy to decrease. During milling, the milling cutter will generate a lot of heat during the milling process, so coolant is needed, and it needs to be discharged after cooling. In the milling process, the removed part of the workpiece will become fine metal flakes. Since the metal flakes are thin and the hard rail guide width is limited, it is not easy to clean. If you accidentally touch the metal flakes during cleaning, you will be easily cut. For example, a Chinese patent discloses "A CNC gantry milling machine for a CNC machining center", and its application number is: "CN202110915838.3", which includes: a base and an electric control slide, two of which are fixedly installed on the left and right sides of the top of the base, a processing platform, fixedly installed on the top of the output end of the two electric control slides, and an installation groove. The device is not convenient for the discharge of coolant, and the cut iron chips are not easy to clean, and its applicability is relatively limited. Utility Model Content
