Description

Technical Field

[0001] The invention relates to the technical field of milling machines, in particular to a milling machine for machining racks with high precision. Background Art

[0002] Milling machines play an important role in mechanical manufacturing, mold processing, aerospace, automobile manufacturing, and military manufacturing. They are one of the key equipment for achieving high-precision and high-efficiency processing. Milling machines are needed in the rack processing process to cut the workpiece through rotating tools.

[0003] For example, a Chinese patent with a publication number of CN219234716U discloses a milling machine, comprising: a milling machine body, a support column is installed on the outer wall of the milling machine body, a No. 1 plate is arranged at the bottom of the milling machine body, a No. 2 plate is installed on the bottom of the milling machine body, a motor is installed on the inner wall of the mounting frame, a threaded screw is installed on the outer wall of the motor, a slider is installed around the outer wall of the threaded screw, a connecting rod is installed on the outer wall of the slider, and a scraper is installed on the outer wall of the connecting rod.
