Description

Technical Field

[0001] The present application relates to the field of rotary conversion cutting components, and in particular to a rotary conversion cutting component for a gantry CNC milling machine. Background Art

[0002] CNC gantry milling machine, also known as gantry milling machine, is a milling machine with a gantry frame and a long horizontal bed. Multiple milling cutters can be used to process surfaces at the same time on CNC gantry milling machine, with high processing accuracy and production efficiency, and is suitable for processing planes and inclined surfaces of large workpieces in batch and mass production. CNC gantry milling machine can also process space curved surfaces and some special parts. When processing large workpieces, existing CNC gantry milling machines need to replace different milling cutter groups according to the processing requirements of the workpiece to complete the processing tasks of different parts of the workpiece, but the milling cutter groups of existing CNC gantry milling machines are not easy to replace, which reduces the processing efficiency of the workpiece.
