Abstract

A machining center for reducing workpiece damage comprises a tool body, a tool saddle, a column, a machine head, a worktable, a spindle, a knife magazine moving guide rail, a knife magazine installing plate, a knife, a limiting block, a hydraulic oil buffer and a driving device. The tool saddle and the worktable are installed on the tool body, and the column is installed on the tool saddle. The knife magazine moving guide rail is installed on the tool body, and the knife magazine moving guide rail and the worktable are located on the same side of the tool body. The knife magazine installing plate is installed on the knife magazine moving guide rail, the knife is installed on the knife magazine installing plate, and the limiting block is installed on the side, adjacent to the worktable, of the knife magazine moving guide rail. The hydraulic oil buffer is installed on the limiting block. The driving device drives the knife magazine installing plate to move on the knife magazine moving guide rail. The workpiece damage caused by too large bumping force between the knife magazine installing plate and the worktable in the moving process and too large noise produced during bumping are avoided through the limiting block and the hydraulic oil buffer.
