Description

High-precision metal cutting equipment Technical Field The utility model relates to the technical field of automobile skylight guide rails, in particular to high-precision metal cutting equipment. Background When the car skylight guide rail is processed, redundant materials of the car skylight guide rail are needed to be cut off by using a sawing machine, the skylight guide rail is cut into proper lengths, and after the guide rail is completely processed, the guide rails with different lengths are assembled together to form an integral car skylight guide rail, so that the car skylight guide is controlled to move, and the car skylight is conveniently opened and closed. The Chinese patent CN221639671U discloses a cutting device for an automobile skylight guide rail, which relates to the technical field of automobile skylight guide rail processing and comprises a storage rack, wherein the top position of the storage rack is slidably connected with a first sliding rack, the front end position of the top of the first sliding rack is slidably connected with a second sliding rack, the front end position of the second sliding rack is L-shaped, and the middle position above the inside of the second sliding rack is fixedly connected with a reversing rack.
