Vertical milling machines are relatively flexible, and the worktable can be raised and lowered. End mills, machine clamp cutters, drill bits, etc. can be used to mill keyways, flat surfaces, boring holes, etc.
Horizontal milling machines can mainly use hangers to enhance the strength of the tool, and can mill slots, mill planes, cut off, etc.
Gantry milling machine, referred to as gantry milling machine, is a milling machine with a portal frame and a horizontal long bed. The gantry milling machine can use multiple milling cutters to process the surface at the same time. The processing accuracy and production efficiency are relatively high. It is suitable for processing the flat and inclined surfaces of large workpieces in batch and mass production. CNC gantry milling machines can also process spatial curved surfaces and some special parts
