This invention relates to a sawing and milling processing unit, processing center, and working method suitable for curtain wall profiles. The milling mechanism is used to perform sawing or milling operations. A sawing and milling fixture is used to clamp and fix the profile in both vertical and horizontal directions. The clamping block of the sawing and milling fixture, driven by a cylinder, moves vertically towards a fixed roller to achieve vertical clamping of the profile to be processed. The fixed roller has a semi-circular cross-section, with multiple sets of parallel air holes arranged in the semi-circular area. The line connecting these sets of air holes is located on one side of the fixed roller's axis. The angle α formed by the lines connecting air holes in adjacent sets of fixed rollers in the direction of the fixed roller's cross-section ranges from 100° to 120°. During profile feeding and processing, gas is ejected through the fixed roller, forming an "air cushion" on the bottom surface of the profile. This reduces the pressure of the profile's own weight on the surface of the fixed roller and simultaneously blows away aluminum chips from the bottom surface of the profile, solving the problem of scratches caused by sliding friction between the profile and the fixed roller.
